  • Prof. Ashis Kumar Sen received his B-Tech in Mechanical Engineering from NIT Rourkela, M-Tech in Mechanical Engineering from the IISc Bangalore, and PhD from the USC – Columbia, USA. Following his M-Tech, he worked as a Thermal Engineer at Aavid Thermalloy. After his PhD, he served as a Senior Microfluidics Engineer at Epigem Ltd., UK, where he gained valuable industry experience in microfluidic device development. He then worked as a Research Associate and R&D Engineer at the University of Southampton, UK. Since 2010, he has been a faculty member at IIT Madras. His core research focuses on Microfluidics and Miniaturization Technologies, with applications in Bioengineering and Soft Matter. He has extensive experience in developing microfluidic systems and translating them for real-world applications.
