Dr. Ashis Kumar Sen received his B.E. from NIT Rourkela, M.E. from IISc, Bangalore and Ph.D. from the USC – Columbia, USA. After his M.E., he worked as a Thermal Engineer at Applied Thermal Technologies, Pune. After his Ph.D., he worked as a Senior Microfluidics Engineer at Epigem Ltd, UK and subsequently as a Research Associate and R&D Engineer at the University of Southampton jointly with the Sensors group at the National Oceanography Centre, UK. He has been a faculty at IIT Madras since 2010.

His research interests are mainly in the areas of Micro/nanoscale Interfacial Phenomena and Lab on Chip technology.
