About

Dr. Samaresh Das is Associate Professor at the Centre for Applied Research in Electronics(CARE), IIT Delhi, India. He received the M. Sc. and PhD degree from Indian Institute of Technology Kharagpur, India, in 2005 and 2011, respectively. At Indian Institute of Technology, his research involved on Ge quantum dot based floating gates, light emitters and photo-detectors on silicon substrate. He then worked as a researcher in the Ultimate Silicon Device Group led by Prof. Jean-Pierre Colinge at Tyndall National Institute, Ireland. There he worked on the fabrication and characterization of Junctionless Nanowire Trigate MOSFET. He worked as a Research Scientist at Hitachi Cambridge Lab-Cavendish Lab, University of Cambridge on Quantum Information Project for the development of scalable silicon charge qubit. In September 2014, he joined Centre for Applied Research in Electronics, Indian Institute of Technology Delhi as an Assistant Professor. His research group IIT Delhi is working on the development of efficient infrared photodetectors, THz electronic devices, quantum information technology and on electronic bio-sensors.He is a recipient of Faculty Research Award (2019, IIT Delhi), Institute for Smart Structures and Systems (ISSS) Young Scientist Award-2019, Indian National Academy of Engineering (INAE) Young Engineer Award-2017, and MeitY Visvesvaraya Young Faculty Research Fellowship Award.
