either Department of Applied Math & Statistics [link]
or Computer Science [link].
If
you are already at Stony Brook University as a PhD, master, or undergraduate
student and interested in my research and joining my group, feel free to send
me an email. [About Me] [Publications] [Awards] [Teaching] [Projects] 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 and Smart Energy Technology Cluster. I received my Ph.D.
degree in Computer Science at the California
Institute of Technology, where I was co-advised by Prof. Adam Wierman and Prof. Steven Low. Before
Caltech, I received my M.S. degree of Computer
Science & Technology in 2009 and B.E. degree of Measurement
& control in 2006, both from Tsinghua
University with honor. I also received a dual degree of Economics from Peking University in 2009. Here is my Curriculum Vitae. My current research interests include cloud computing,
online convex optimization, energy-efficient computing, machine learning,
internet of things, market design, distributed control. My research
combines rigorous analysis and system design, and goes from theory, to
prototype, and eventually to industry to make real impacts. Selected

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. -
