Research Interests | |||||

Broadly, I am interested in theoretical problems related to the theme `Optimization Under Uncertainty'. More particularly, I am currently working on combinatorial optimization problems and my uncertainty models are inspired from areas such as Online & Approximation Algorithms, Stopping Theory, Learning Theory, Stochastic Modeling, and Algorithmic Game Theory. | |||||

Biography | |||||

I am a PhD student in the School of Computer Science at Carnegie Mellon University. I am fortunate to have Prof Manuel Blum and Prof Anupam Gupta as my advisors.
Before coming to CMU, I finished my masters under the supervision of Prof S. Keshav at the Cheriton School of Computer Science, University of Waterloo.
I obtained my undergraduate degree in computer science from the Indian Institute of Technology, Delhi.
I am supported by a CMU Presidential Fellowship.I am looking for a Postdoc starting August, 2018.
