About Me
I am currently an assistant professor in the Department of
Applied Mathematics and Statistics. I am also affiliated with Department of
Computer Science department. I received my Ph.D. degree in Computer Science
at the California Institute of Technology,
where I worked with Prof. Adam
Wierman and Prof.
Steven Low.
My research aims to develop analytical models, theoretical
results, and deployable algorithms to manage complex distributed systems with
limited information and network constraints. Three thrusts form the
theoretical foundations, namely, online optimization, distributed control,
and mechanism design. Moving from theory to practice, I have worked actively
with industrial partners to implement some of my results to make real
impacts.
Please see my research interests
and publications below for more information. Feel free to email me if you
want to learn more about my research and are interested in joining my group.

Project: Sustainable Data Center
-
Impacts: I helped HP design and implement the industrial
first Net-Zero Energy Data Center, which has been widely reported in
media and news, e.g. the Wall Street Journal, Com- puterworld, Wired, ZDNet,
The Register, and was named a 2013 Computerworld Honors Laureate.
Additionally, the results of my research provided insight and guidance into
the design and management of HP EcoPOD data center, which has been used by
many major IT companies, e.g., Facebook, eBay, Apple, and research institute,
e.g., National Renewable Energy Laboratory, and won the 2013 InfoWorld Green
IT Award.
