"I'd like to congratulate Professor Calo on this spectacular achievement,” said Dean Larry Larson. “Becoming a Fellow of the ACS is a recognition of a lifetime of technical contributions and service to the American Chemical Society. Professor Calo's contributions to Brown and to Chemical Engineering have been and continue to be extraordinary."
The fellows program began in 2009 as a way to recognize and honor ACS members for outstanding achievements in and contributions to science, the profession, and ACS.
