Research & Scholarly Activities
I joined Manhattan College in Fall 2017 after being a member of the faculty of Chemical Engineering at the University of Toledo (UT) for almost three decades. I received an MS from the Indian Institute of Technology, Kanpur, India in 1977 and a PhD from the State University of New York (SUNY) at Buffalo in 1983. At Buffalo, I did my doctoral research in the area of interfacial phenomena under the supervision of Distinguished University Professor Dr. Eli Ruckenstein, who was a recipient of the National Medal of Science from President Bill Clinton. For my doctoral dissertation, I studied electro kinetic transport phenomena in porous media. Soon after receiving Ph.D., I joined the University of Toledo (UT) as an Assistant Professor of Chemical Engineering, and was promoted to the rank of Full Professor in 1993.
While my initial research thrust was in the area of Colloid and Interfacial Science, I diversified into the area of “alternate energy” around 2005 and, in particular, to biomass conversion to fuels and value-added products. Along with my colleagues at UT, I developed a new and cost-effective technology for the fractionation of lignocellulosic biomass using ionic liquids, which has subsequently become the platform technology for the DOE laboratory Joint Bioenergy Institute (JBEI) in Emeryville, CA for biomass deconstruction. I authored, with my colleagues at UT, more than 60 peer-reviewed publications in this area in high-impact ACS and RSC journals and received 20 patents. Majority of our patents have been licensed to start-up companies, and one of them, SuGanit Systems Inc. has a pilot-scale facility for second generation biofuel production operating on the University of Toledo Campus. We have received funding in excess of thirteen million dollars ($13M) in support of our work from federal, state, and private sources, including the National Science Foundation, US Department of Energy, USDA (NIFA), US Air Force Office, Ohio Third Frontier Commission, and SuGanit Systems Inc.. I have supervised over 25 graduate students in the areas of ionic liquid pretreatment of lignocellulose, bio-refining methods based on Furan platform, and fermentation technologies for converting biomass-derived sugars to fuel precursors and organic acids for materials production.
I routinely participate as a panelist and ad-hoc reviewer by federal agencies including National Science Foundation (CBET: Energy for Sustainability division), DOE and ARPA-E to evaluate new technologies related to biomass conversion and for adjudication of NSF–CAREER awards. I am a senior member of the American Institute of Chemical Engineers, American Chemical Society, and Society of Industrial Microbiology and regularly chair sessions at international conferences in the area of biofuels and products. I received Outstanding Researcher Award from the College of Engineering at UT in 1994, and Outstanding Researcher Award from the University of Toledo in 2015. I have taught majority of the required under-graduate courses in the chemical engineering curriculum at UT.
