NeuroComputing and Hardware Security (NeuroCHaSe) Group
Department of Electrical Engineering,
Indian Institute of Technology, Kanpur
Welcome to the homepage of Dr. Shubham Sahay
The general focus of my NeuroComputing and Hardware Security (NeuroCHaSe) research group is on the development of (a) novel hardware platforms to perform energy-efficient computation and (b) novel hardware security primitives to protect the cyber-physical systems against security vulnerabilities and adversary attacks.
Our research thrust is highly inter-disciplinary in nature and exploits principles and knowledge accumulated from semiconductor device physics, VLSI circuit design, computational neuroscience, Machine learning, etc., involving both experimental characterization and theoretical work.
