Biography:
Gregory Botsaris accomplished his undergraduate studies at the National University of Athens, Greece. He received three graduate degrees from M.I.T. including a Ph.D. in chemical engineering in 1965. The same year he became an Assistant Professor in the Department of Chemical Engineering at Tufts University. He was promoted to Associate Professor in 1969 and to Professor in 1975. Since 2004 he has continued his service at Tufts as Professor Emeritus and Research Professor. Between 1983 and 1993 he served as the department chair.
Throughout his career at Tufts, Professor Botsaris worked tirelessly to enhance the department of Chemical Engineering. During his chairmanship the department moved to its present home in the Science and Technology Center, and its number of faculty and graduate students increased appreciably. He also created the first Biotechnology Engineering Center, ushering bioengineering activities in the School of Engineering.
His research work has centered around two fields: crystallization and stability of colloidal dispersions. His research in dispersions involved the stabilization of coal-water slurries and their use as alternative fuels in the power industry. In 1981 he was a member of a DOE-led delegation that visited China, at the invitation of the Chinese government, for exchanging technical information on coal utilization in the form of slurries in water. A book on “Interfacial Phenomena in Coal Technology” was edited by Professor Botsaris in 1989.
The heart of his crystallization work involves the investigation of secondary nucleation and the effect of additives on crystal growth. His first Ph.D. student used chiral crystals in 1970 as a probe of the mechanism of secondary nucleation. This work was revisited and refined in the last seven years and led to a novel model for secondary nucleation. This model has important implications for the separation of chiral drugs by crystallization in the pharmaceutical industry.
In the 1990s Professor Botsaris also studied certain environmental applications of crystallization: namely, the freeze concentration of the bleaching effluents of the paper pulp plants and the production of the new road deicer, calcium magnesium acetate, by a process involving crystallization.
