About me

Welcome to my home on the web! My name is Frank, I am currently a Software Engineer (SDE-II) at Amazon AWS.

Before joining Amazon, I was an ECE Ph.D. student from the University of Illinois Urbana-Champaign (UIUC) under Prof. David M. Nicol. My research combined network security, graph theory, probability theory, and quantitative risk to answer a fundamental question "how to accurately and efficiently estimate the risk of cyber-attacks against networks?" The answer to the question helps network defenders make timely, optimal, and risk-informed defense decisions proactively and reactively--i.e., prior to and during a network breach.

Prior to Illinois, I worked for four years as a full-time Software Engineer at the Advanced Digital Sciences Center (ADSC), a Singapore-based research center established and led by UIUC and funded by Singapore's Agency for Science, Technology, and Research (A*STAR). I worked with Prof. Ravishankar Iyer, Prof. Zbigniew Kalbarczyk, Prof. David Yau, Prof. Rui Tan, Prof. Binbin Chen, and Dr. Daekwoo Jung on smart grid security, demand response, building energy efficency, and wireless sensor networks.

I got my bachelor degree in Computer Engineering from the School of Computing, National University of Singapore (NUS) in 2011. In my undergrad thesis, I designed a control scheme to save mobile device's battery power by adapting the LCD screen brightness level to the ambient light and the running applications.
