I am a PhD candidate in Computer Science at Caltech, and a member of Netlab and the Rigorous Systems Research Group (RSRG), working with Professor Adam Wierman and Professor Steven Low. My research interests lie in online algorithms, optimization and mechanism design and their applications to the future energy systems. My CV is available here.
