Undergraduate Research Profiles

Sharon Makava started at Brown as an engineer with health-related interests. Her initial interests led her to biomedical engineering, but she is now pursuing Chemical and Biochemical Engineering degree. Her interactions with her former concentration advisor, Professor Tripathi, led her to her current work in his lab. She is working on K103N mutation in the HIV virus with graduate student Kenny Morabito. They are working to isolate and amplify the mutation at low sample concentrations. The end goal is to develop a test diagnostic which will allow doctors to look for a drug resistance amongst their patients. Her current research will give her a strong foundation to pursue industry or academic directions in the future, but for now she says “she can’t imagine being anywhere else.”
Eli Fine understands the importance of being aware of your intentions when you speak. He gained this appreciation through a linguistics class he took as part of Brown's open curriculum elective options. He has not only gained a greater appreciation for the scientific world, but also anthropology, philosophy, psychology, and linguistics. His collaborative spirit fits well with the interdisciplinary group of mathematicians, engineers and biologists he researches with in his multiple research projects at Brown.
Carmichael Ong is an intricate mix of biologist, biochemist, and bioengineer. He has the network to prove it. Carmichael has worked on two large interdisciplinary research projects at Brown in his undergraduate career. He believes that the intimate atmosphere within Brown Engineering and the approachable faculty are major benefits to his future. He plans to continue as a researcher in his future career either in industry or academia. Regardless of which direction he chooses, he will understand how to network with top rate researchers in an interdisciplinary setting because of his experience at Brown.
Ben Howard understands what it would take to be a Mythbuster on the Discovery Channel. He understands engineering and science principles and appreciates photography and video production. As a cinematographer for BTV (Brown’s Television Station) he produces his own tv show. Beyond just being inspired to record the world around him in unique ways, Ben is a design-oriented engineer. He found his way to Professor Breuer’s lab after having him for Thermodynamics class. His summer work extended into a larger research project to create a prototype that can create liquid droplets out of oil – a humidifier of sorts for oil. In Breuer’s lab, they have learned to use photography to study the aerodynamics of bat flight. They can record two flash photographs and record the velocity based on the distance the droplets have traveled around the bat’s wings. Most of the science is stumped on how bats accomplish their flight patterns. The Mythbusters wouldn’t even be able to figure it out, but Ben and other Brown engineers will eventually.
Juri Minxha works at the interface between engineering and neuroscience. He came to Brown uncertain of what he hoped to accomplish during his four years here. He found that the introductory engineering courses gave him a chance to test drive all of the related engineering fields. He also used the open curriculum to his advantage and took neuroscience courses. This background led him to Professor Palmore’s lab where he works at the interface of electrical engineering and neuroscience. He understands the importance of this research and hopes to continue his scholarship in a graduate program.

Many of our students are awarded annually with Halpin awards for their interdisciplinary research. To read more about the Halpin awards and the students profiled, click here.

Presented by the Superfund Research Program - www.brown.edu/sbrp

Childhood asthma is at near epidemic proportions in parts of New York City, affecting as many as one quarter of all elementary aged children in certain under-served minority neighborhoods of the city. There is also an increasing body of evidence indicating that living near to traffic is associated with increased respiratory problems in children. Exposure to fine particles from diesel vehicles is suspected as a likely causal agent in these associations between traffic and asthma, but there is only limited information relating personal exposures to diesel particles and health for individual children. This seminar introduces both the asthma problem in New York City and the recent evidence regarding asthma and diesel air pollution, and then presents recent in-press results of a study conducted by NYU in the South Bronx that has directly tested the relationship between childhood asthma symptoms and personal exposures to diesel particles. Options available to control diesel emissions in New York City and elsewhere are also discussed.

Professor Allan Bower publishes new book, Applied Mechanics of Solids

Professor Allan Bowers new book, Applied Mechanics of Solids, comes out today, October 1, 2009.

Applied Mechanics of Solids summarizes the physical laws, mathematical methods, and computer algorithms that are used to predict the response of materials and structures to mechanical or thermal loading.

Topics include: the mathematical descriptions of deformation and forces in solids; constitutive laws; analytical techniques and solutions to linear elastic and elastic-plastic boundary value problems; the use and theory of finite element analysis; fracture mechanics; and the theory of deformable rods, plates and shells.

Over 400 practice problems are provided on a companion web site, as well as demonstration finite element codes in MAPLE and MATLAB. The text is intended for advanced undergraduate or graduate students, as well as practicing engineers and scientists. It will be particularly useful to readers who wish to learn enough about solid mechanics to impress their teachers, colleagues, research advisors, or managers, but who would prefer not to study the subject in depth.

An electronic version of the text can be accessed at http://solidmechanics.org and its also available from Amazon.

Audio Insights: Nanovis developing nanosurface technology

Listen to audio excerpts from a recent highlight interview with Professor Thomas Webster talking about his start-up company Nanovis.

Nanovis' leaders say, depending on the type of conventional implant, up to five percent can become problematic because the body rejects it, recognizing it as a foreign object because its smooth surface doesn't match the rough surface features of human tissue. However, the nanosurfaced implants Nanovis is developing feature a "roughness" that mimics human tissue, allowing the body to "accept" them. Webster says the nanosurfaced implants decrease infection, reduce the growth of scar tissue and promote the growth of healthy tissue. Listen

Using the same core idea of mimicking the natural roughness of human tissue, Nanovis is developing nanosurface technology for orthopedic, spinal, dental, cardiovascular and soft tissue implants. Listen

"It's a pretty exciting time for me as a researcher and a pretty exciting time for this mysterious sounding field of nanotechnology. There's actually real world application for this field—not just the nano iPod!" laughs Webster. "There are actual medical devices and real clinical treatments that can benefit from nanotechnology."

Testing nanomaterials for safety

"Scientists are preemptively testing the potentially ill effects of the tiny molecules and even atoms engineered at the scale of one billionth of a meter or smaller."

Carbon nanoparticles appear to be benign when fed to fruit fly larvae, but adults exposed to the nanoparticles in powdery form are not as lucky. Research led by David Rand and Robert Hurt show two varieties of carbon nanoparticles stuck to the flies, impeded them from climbing and ultimately caused them to die.

Tissue engineering research at Brown

Codirector of Brown University’s Center for Biomedical Engineering, Jeff Morgan leads a team of scientists who have developed novel ways of forming individual cells into living tissue. Some day, their techniques, in combination with stem-cell technology, could cure or lessen the suffering of diabetes and other debilitating diseases.

Strictly speaking, Morgan is a tissue engineer –– one of a substantial number of scientists around the world who are learning how to create groupings of cells that mimic the function of tissues or organs. Formed in the laboratory, these tissues can be transplanted into living creatures. Research is still largely confined to experimental animals –– but success so far in mice and rats holds great promise for humans.

Morgan’s advance is his unique method of growing and assembling individual cells into larger clusters –– what he calls the potential “building blocks” of tissues and organs that could be produced on demand.

Alumni develop sleep analyzer

In 2003, three Brown University undergraduates, Eric Shashoua, Ben Rubin and Jason Donahue, sat in a school cafeteria and mused about their grogginess after an all-night study session. They knew that the stress of exams played a role, but they started wondering about the science of their exhaustion.

Little did they imagine that their discussion would eventually lead to the founding of Zeo, maker of the first direct-to-consumer sleep device that analyzes nighttime sleep patterns. Zeo's product, the Personal Sleep Coach, uses a soft headband loaded with sensors to monitor brain waves. The data are sent wirelessly to a small device on a nightstand; from there they can be uploaded to the MyZeo.com Web site. MyZeo.com then analyzes the data and e-mails back a strategy and suggestions for improving the next night's sleep.

However, once these three would-be entrepreneurs decided to create a science-based aid for the estimated 70 million Americans suffering from chronic sleep disorders, they realized they were lacking a key ingredient: an investor--or several--to fund their research and development.

Initial fundraising began in the cafeterias at Brown. "We literally went table-to-table to talk about our innovation and get people interested in contributing," Shashoua recalls. Those discussions led to introductions to wealthy Brown alumni, experts in sleep research and so-called "angel investors."

Indo-US Science and Technology Forum collaborates with Brown

Created in March 2000, the Indo-US Science and Technology Forum (IUSSTF), established under an agreement between the Governments of India and the United States of America functions to synthesize collaborative research and promote substantive interaction among government, academia and industry. The overall goal of IUSSTF is “to provide opportunities, to exchange ideas, information, skills and technologies, and to collaborate on scientific and technological endeavours of mutual interest that can translate the power of science for the benefit of mankind at large.” (http://indousstf.org/) 

This Forum has a specific biomaterials area in which Brown University and Indian Institute Technology (ITT) Kanpur (along with other affiliated schools and companies) had a competitive proposal accepted in November 2008.  Co-Coordinator Bikramjit Basu of ITT Kanpur most recent visit in Phase I of this project was to fellow coordinator Thomas Webster at Brown University.  This July 2009 visit included many collaborative meetings and a talk on the biomaterials research in Dr. Basu’s lab.  The goals of these types of visits are to facilitate collaboration and increase their outreach potential.  A core deliverable of the project is to “train the next generation of scientists in the international interdisciplinary arena.” (http://www.iitk.ac.in/indo_us_biomaterials/)  

Dr. Basu explains, “This collaboration depends on the two way visits between researchers in the US and India.”  It is clear that these visits help researchers develop concrete projects. The dialogue between the different institutions and researchers allows for sharing of research results and a better understanding of the challenges faced by each group.  The biomaterials area specifically faces the unique challenge of bridging the gap between traditional biology and materials engineering.  The next steps for this project include working to integrate more industrial partners and medical professionals into the research collaborations.

Breuer collaborates on bat research

An excerpt from a recent Forbes article:
Researchers at Brown University are three years into another Air Force grant, this a five-year, $6 million grant shared among five other universities, to understand perhaps the most impressive fliers of all--bats.

Unlike insects and birds, bats have long thin fingers that reach through their wings, and their wings are made out of an extraordinarily stretchy membrane. This allows them to twist and shape their wings in ways that other creatures can't, and so maneuver quickly and accurately through tight spaces like caves. They can take off almost vertically from the ground and they can take off hanging upside down.

"Nature does many, many things we don't know how to do in engineering," laments Kenneth Breuer, an engineering professor at Brown and the principal investigator on the Air Force grant.

Breuer and his Brown colleague Sharon Swartz, an evolutionary biologist, put bats in wind tunnels and study how they move their wings during takeoff, flight and landing. Using lasers that illuminate tiny particles in the air flow created by the bats' wings, the researchers study the turbulence created.

Bat research highlighted in Forbes on June 26, 2009.

Nanoparticles eliminate bacterial infection on prosthetic

Infected implants now have a foe. Brown University researchers have created a nanoparticle that can penetrate a bacterial-produced film on prosthetics and kill the bacteria. The finding, published in the International Journal of Nanomedicine, is the first time that iron-oxide nanoparticles have been shown to eliminate a bacterial infection on an implanted prosthetic device.

Hydrodynamics of Microorganisms

Professor Powers' article, Hydrodynamics of Swimming Mircoorganisms, was accepted this week in Reports on Progress in Physics.
Preview the article here: http://dl.getdropbox.com/u/652169/reviseLaugaPowersv3.pdf
Abstract.
Cell motility in viscous fluids is ubiquitous and affects many biological processes, including reproduction, infection, and the marine life ecosystem. Here we review the biophysical and mechanical principles of locomotion at the small scales relevant to cell swimming, tens of microns and below. At this scale, inertia is unimportant and the Reynolds number is small. Our emphasis is on the simple physical picture and fundamental flow physics phenomena in this regime. We first give a brief overview of the mechanisms for swimming motility, and of the basic properties of flows at low Reynolds number, paying special attention to aspects most relevant for swimming, such as resistance matrices for solid bodies, flow singularities, and kinematic requirements for net translation. Then we review classical theoretical work on cell motility, in particular early calculations of swimming kinematics with prescribed stroke and the application of resistive-force theory and slender-body theory to flagellar locomotion. After examining the physical means by which flagella are actuated, we outline areas of active research, including hydrodynamic interactions, biological locomotion in complex fluids, the design of small-scale artificial swimmers, and the optimization of locomotion strategies.

In addition, some of his recent work was highlighted on the NSF news page:
Scientists studying how marine bacteria move have discovered that a sharp variation in water current segregates right-handed bacteria from their left-handed brethren, impelling the microbes in opposite directions. This finding and the possibility of quickly and cheaply implementing the segregation of two-handed objects in the laboratory could have a big impact on industries like the pharmaceutical industry, for which the separation of right-handed from left-handed molecules can be crucial to drug safety.

Biosensor to Measure Vitamin D Levels

A team from Professor Palmore's lab consisting of two grad students (Steve Rhieu and Vince Siu) and one undergraduate (Daniel Ludwig, '09) is in the Finalist round of the BMEIdea 2009 competition on June 9th – June 11th, in New York City, New York. This work was made possible by an OVPR seed grant and has a preliminary patent application submitted.

Here is the brief project summary:

We propose a new methodology to measure vitamin D levels in serum using electrochemical detection. Vitamin D is a prohormone that is hydroxylated in the liver to become 25(OH)D, which is further hydroxylated in the kidney by the enzyme CYP27B1 to become the biologically active form. The electrochemical approach is based on the hypothesis that the hydroxylation of 25(OH)D can be measured via the catalytic reaction of CYP27B1 immobilized on an electrode. The reaction requires a supply of electrons, generating a detectable current that is proportional to the concentration of 25(OH)D. Similar to a commercial glucose meter, our proposed vitamin D biosensor will use a disposable testing strip that is inserted in the portable device along with a sub-microliter sample. The sample is analyzed and the result is displayed both qualitatively and quantitatively on a liquid crystal display. Specific recognition of 25(OH)D by a CYP27B1-based electrode system eliminates the need for extensive extraction and/or purification of the sample allowing for inexpensive, accurate, and rapid measurements.

Gao receives award

Huajian Gao has been selected to receive the 2009 Robert Henry Thurston Lecture Award from the American Society of Mechanical Engineers “for groundbreaking research on mechanical properties of both engineering and biological systems across multiple length scales”. Formal presentation of the award is scheduled to take place at the Robert Henry Thurston Lecture, during the ASME International Mechanical Engineering Congress & Exposition, November 13-19, 2009.

About the Robert Henry Thurston Lecture Award:

The Robert Henry Thurston Lecture was established in 1925 in honor of Robert Henry Thurston (Brown, B.S., Civil Engineering, 1859), the first president of ASME and a farseeing leader in science and engineering. The Robert Henry Thurston Lecture, presented annually at the International Mechanical Engineering Congress, provides an outstanding leader in pure or applied science or engineering with the honor of presenting to the Society a lecture that encourages stimulating thinking on a subject of broad technical interest to engineers. The Robert Henry Thurston Lecture was elevated to a Society award in 2000.

Robert Henry Thurston (1839-1903) was born in Providence, Rhode Island. His father, Robert Lawton Thurston, manufactured steam engines in Providence. The young Robert Henry Thurston went to Brown University, where he graduated as a civil engineer in 1859. He was the first professor of mechanical engineering at Stevens Institute of Technology (in 1871). There he established Stevens’ mechanical engineering curriculum. Historians credit Thurston with establishing the first US mechanical engineering laboratory for conducting funded research at an academic institution for higher learning. He was the first president (1880-82) of the American Society of Mechanical Engineers.

Webster discusses intricacies of nanomaterials

Excerpts from Globe and Mail article:
Thomas Webster, an associate professor of engineering at Brown University in Providence, R.I., says that to peer at the intricacies of various tissues, such as bone or skin, through a super-powered microscope is to enter the nano world at a glance.

“Toxicity is incredibly important for us to understand when we're making these materials or when we're using them,” said Dr. Webster, whose own research includes designing nanomaterials for such orthopedic applications as joint replacements and limb prosthetics.

Renaissance Engineer Series

Focus on: Leadership - Brown ENGINEERING PROFILES
How our Engineering Alumni are creating change through innovative leadership

Excerpt from Dean's Message:
"I want to use this issue to begin engaging our graduates and students in changing the perception of the roles that engineers can play in our society - and need to play if we are to address effectively the complex issues that we face in energy, environment, clean water, health care, climate change, and even the world economy. Engineers today need to be understood, not as merely workers with valuable technical training, but as highly-capable, broadly-prepared people who bring a deep understanding of science, math, and engineering know-how to the solution of problems that challenge our society....Preparing engineers for truly difference-making careers is Brown’s challenge - and its responsibility in view of the high potential of students who choose to study here."

eMotive: Out of Gas

RISD design students and engineering majors from Brown University combined their problem-solving resources in fall 2008 to tackle a growing global problem: the need for affordable, flexible transportation powered by renewable fuel sources. An outgrowth of the eMotive project – an ongoing collaboration between Industrial Design faculty Khipra Nichols BID ’78 and Michael Lye ’96 ID and Brown Engineering faculty Chris Bull – the Out of Gas! studio focused on the needs of urban commuters, using Providence as a test case.

Lye and Bull team-taught the studio, which brought together roughly 12 students from RISD and 12 from Brown to explore “where and how industrial design and engineering intersect” in the context of a real-world problem, Bull explains. In addition to reaping the benefits of complementary expertise, the students took full advantage of both institutions’ specialized facilities: the metal, wood and model shops at RISD, and the Prince Engineering Lab at Brown, which offers access to CNC and rapid prototyping technology.

Canadian Press article featuring nanoscience

Tiny particles lead medicine from science fiction to nanorobots fighting cancer
Jan 7, 2009

Article Excerpt:
Thomas Webster, an associate professor of engineering at Brown University in Providence, R.I., says that to peer at the intricacies of various tissues, such as bone or skin, through a super-powered microscope is to enter the nano world at a glance.

"What we're finding out is that nanomaterials make up our tissues," says Webster, editor-in-chief of the International Journal of Nanomedicine, who points as an example to enzymes and proteins that power the functions that give us life.

"So we are walking nano things. We are assembled from nanomaterials."

Webster Named as Co-director

Webster Named as Co-director of New Indo-U.S. Center for Biomaterials for Health Care

Nanosatellite Launch Vehicle Conference

In the over 25 years since small, low cost space began its transition from curiosity to the integral element of world-wide civil and military space it is today, transportation to orbit has remained a critical constraint. Despite worldwide government and private investment exceeding $500M, there exists no dedicated micro / nano satellite launcher compatible with the low cost, rapid development schedule and reliability of their small satellite payloads.

On November 7, 2008, Brown University, in conjunction with NASA Ames Research Center, and NASA Rhode Island Space Grant will host a one day conference and workshop bringing together the government, commercial and academic teams planning these new vehicles, with some of their potential suppliers, end users and sponsors.

We had about 45 people attending, including students from Brown, USC, Stanford, University of Michigan. RI Space Grant provided student travel. We had speakers from several small entrepreneurial launch companies, NASA Ames Research Center, US Army Redstone Arsenal, Cornell, Brown Stanford and the Naval Postgraduate School.

New Book from Webster on Nanoparticle Safety

Thomas J. Webster Publishes New Book on “Safety of Nanoparticles: From Manufacturing to Medical Applications”

Thomas J. Webster (Associate Professor, Division of Engineering and Department of Orthopedics, Brown University) has just published a new book on the “Safety of Nanoparticles: From Manufacturing to Medical Applications” by Springer. In spite of the potential use of nanomaterials as tissue engineering devices, implants, biosensors, drug delivery devices, etc., there has yet to be a compilation of the risks associated with the in vivo use of nanomaterials. There are numerous and well-known risks because of the size of nanoparticles. For example, nanoparticles can cross cell membranes and enter the cytoplasm undetected. The aim of this book is to provide one of the first detailed overviews of how cells and tissues in the body deal with nanoparticles. This is important not only for implantable devices, but also for the manufacturing of nanophase materials when particles can be inhaled or enter the body through the skin. This new book compiles research at the intersection of nanoparticles and biological processes to determine if nanophase materials are safe to be manufactured, handled, and/or implanted for various medical applications.

Nanotech to regrow cartilage

Excerpt from full article available here: http://www.sciam.com/article.cfm?id=nanotech-cartilage
Thomas Webster, an associate engineering professor at Brown University, and Brown researcher Dongwoo Khang, along with Grace Park, a research scientist (and one of Webster's former PhD students) at Becton, Dickinson and Company, a Franklin Lakes, N.J.–medical technology firm, say they grew cartilage cells by placing chondrocytes (cartilage-forming cells) and carbon nanotubes together on a polycarbonate urethane surface. As expected, cartilage cells grew around the nanotubes, which are so strong that scientists now use them to reinforce plastic. Researchers say they hastened new cell production by sending electrical surges through the nanotubes, which are also excellent conductors of electricity

Engineering course develops toys for rehabilitation

"Crisco was teaching an engineering course that combined industrial science students from Rhode Island School of Design (RISD) and engineering studies students at Brown University. The pair believed this was a perfect forum to bring creative minds together to create some prototypes for new therapeutic toys. Thus, Toys and Technology for Rehabilitation was formed."

Major NIH Grant awarded

Associate Professor Diane Hoffman-Kim and Professor Tayhas Palmore earned a major NIH grant together.

Project Title: Quantifying Axon Growth in Complex Environments

Nerves fail to regenerate after injury and current medical practice is unable to manipulate effectively the process of nerve regeneration. The proposed research seeks to solve this problem by quantifying how guidance cues, both individually and in combination, promote axon growth in an inhibitory environment such as a nerve injury site.

Sirinrath Sirivisoot Highlighted

Sirinrath Sirivisoot highlighted for talk at the Materials Research Society International Materials Research Conference in Chongqing, China

Engineering graduate student: Sirinrath Sirivisoot (advisor: Thomas J. Webster) was highlighted for her talk “Controlled Release of Antibiotics from Conductive Polymers for Improving Bone Implants” at the Materials Research Society International Materials Research Conference in Chongqing, China, Wednesday, June 11, 2008. Sirinrath gave a talk concerning the development of intelligent in situ orthopedic implant sensors that can sense the type of new tissue that is growing and respond accordingly. For example, if new bone growth is not occurring, this sensor can release bone growth factors to increase bone growth. As another example, if infection is sitting in, the sensor can release antibiotics.

Freewheeling transport nations on the move

Chris Bull and an early version of the prototype

Excerpt of article:
In the summer of 2004, the two RISD professors teamed up with Chris Bull at Brown। Bull, whose paper- and book-laden office is in Brown's Prince Laboratory, said he had been working on transportation projects, in particular human powered and bio-diesel powered. For the past year, the team has been joined by Matt Forkin, a senior at Brown who is concentrating in engineering and visual technology.

While RISD has a workshop, Nichols said working with Bull at Brown's Prince Lab has allowed the group to "test ideas right away" on full-size prototypes. "We're used to sketching our ideas and working with small hand-held models," he said. The current vehicle is the third version the group has produced -- Prototypes 1 and 2 have since been disassembled with some parts incorporated into Number 3. "They're getting more sophisticated," said Bull. "The power train is pretty well developed." The motorcycle bench gives the vehicle the look of a snowmobile on wheels. Being electric, the engine was silent as the four sat in a row grinning and took a spin around the lab with Lye at the controls. They said they have taken it out on the streets around Brown, attracting bemused attention as they zip silently along. The vehicle is battery powered and can reach 40 miles per hour with a range of 40 miles on one charge. Bull said the batteries need to charge overnight if the onboard charger is used, but can be charged in four hours with a higher-capacity charger. The battery is lead-acid rather than lithium ion. "The price is right," said Bull.
