I am a postdoctoral researcher at the
Department of Electrical & Systems Engineering, University of Pennsylvania, hosted by Profs. George J. Pappas and Alejandro Ribeiro. I am affiliated with GRASP, Alelab, and PRECISE.
Prior to that, I was a postdoctoral research associate at the
Department of Operations Research & Financial Engineering (ORFE), Princeton University, hosted by Prof. Warren B. Powell, and affiliated with CASTLE Labs. I received the PhD degree in Electrical & Computer Engineering from Rutgers University, under the guidance of Prof. Athina P. Petropulu.
My research is in the areas of
machine learning, reinforcement learning, optimization, signal processing, sequential decision making, and risk, and their applications in autonomous networked systems, wireless communications, security and privacy, and system trustworthiness.
I also share common interest with my partner, Ioanna, in the area of urban information systems. To learn more about Ioanna’s research, click
I am joining ! MSU ECE
I am excited to announce that I will be joining the
