While at MIT, he established joint programs with the National University of Singapore which would ultimately become a part of the Singapore-MIT Alliance for Research and Technology (SMART) Centre.
His research on fermentation, monitoring and control of bioprocesses, renewable resource utilization, enzyme technology, product recovery and purification, protein aggregation and refolding, and mammalian cell cultures made him a pioneer in biochemical and biological engineering.
