I am currently working as a Postdoctoral Research Associate under the supervision of Prof. Matthew McKay and Prof. Ross Murch. I obtained my Ph.D. in ECE (with Scientific Computing Concentration) from HKUST in 2022, and B.Tech. in Electrical Engineering (with specialization in Communication System and Networking) from IIT Delhi in 2018. The title of my Ph.D. thesis was “Signal Processing for 6G: From Classical to Quantum Communications“. My Ph.D. research was focused on signal processing for reconfigurable intelligent surfaces (RIS) assisted wireless communications and MIMO terahertz quantum key distribution for 6G wireless networks. My current research interests lies in the intersection of classical and quantum communication technologies for 6G wireless networks including signal processing for RIS, MIMO, QKD and Quantum Information Processing.

Skills: Quantum Information Processing, Machine Learning, Deep Learning, Convex Optimization, Signal Processing, Wireless Communications.
