My research focus is on Hardware and AI-enabled Cyber Security in computer systems, specifically the Internet of Things (IoT). The primary focus of my doctoral studies was on intelligent circuits and architectures utilizing emerging nanoscale electronic devices. In particular, I investigated the utilization of spintronic devices for improving IoT edge devices’ and memory systems’ performance and reliability. These include circuit and algorithmic innovations spanning from initial analog to digital signal conversion up through heterogeneous technology reconfigurable computing fabrics to achieve highly scalable and energy-efficient computing chips. My primary research interests are:

  • Hardware and AI-enabled Security in IoT
  • Neuromorphic and Biologically-Inspired AI Hardware
  • Energy-Efficient and Intelligent Signal Conversion and Processing in IoT
  • Reconfigurable and Adaptive Computer Architectures
  • Low-Power and Reliability-Aware VLSI circuits
  • Emerging Spin-Based Devices
