Biography

Kuang Xu was born in Suzhou, China. He received the B.S. degree in Electrical Engineering (2009) from the University of Illinois at Urbana-Champaign, Urbana, Illinois, USA, and the Ph.D. degree in Electrical Engineering and Computer Science (2014) from the Massachusetts Institute of Technology, Cambridge, Massachusetts, USA. He was a postdoctoral fellow at the Microsoft Research-Inria Joint Center in Paris, France (2014-2015), hosted by Laurent Massoulié.

His research interests lie in the fields of applied probability theory, optimization, and operations research, seeking to understand fundamental properties and design principles of large-scale stochastic systems, with applications in queueing networks, healthcare, privacy and statistical learning theory. He has received several awards including a First Place in INFORMS George E. Nicholson Student Paper Competition, a Best Paper Award, as well as a Kenneth C. Sevcik Outstanding Student Paper Award from ACM SIGMETRICS.


Activities

During the 2012 - 2013 academic year, Kuang Xu was a graduate representative on the MIT Council on Educational Technology (MITCET), and the Institute-Wide Task Force on the Future of MIT Education. Earlier, he served as co-Chair of the 2010 MIT Graduate Orientation during 2010 - 2011, a legislative advocate in the MIT Graduate Student Legislative Action Subcommittee during 2010 - 2011, and a graduate representative on the MIT Corporation Joint Advisory Committee on Institute-Wide Affairs (CJAC) during 2011 - 2012.

Hobbies: classical piano, rock climbing, competitive ballroom dancing (International Latin style), Brazilian jiu-jitsu.
