Short bio
I joined the University of Washington as an Assistant Professor in September
2006. I received a PhD in Industrial and Operations Engineering from the
University of Michigan in 2006, and an MS in Management Science and Engineering from
Stanford in 2003. Before that, I completed my undergraduate education in
Chemical Engineering at the Indian Institute of Technology, Bombay, in 2001.
My field of study is Operations Research. You can
find more about this area at the Institute for Operations Research and the
Management Sciences (INFORMS) website here. More specifically, my work focuses
on stochastic and dynamic optimization problems. I often use dynamic
programming, optimal control, mathematical programming, applied probability,
statistics, and game theory to model and solve these problems.
I am a recipient of the NSF CAREER award and of the
award for Excellence in Teaching Operations Research from the Institute of
Industrial Engineers. My doctoral students have won the Dantzig
dissertation prize and the Bonder scholarship from INFORMS, and other competitive
awards/fellowships from the University of Washington. Upon graduation, my
doctoral students become faculty or work as ÒquantsÓ in finance or service
operations companies.
