I graduated from UC Santa Barbara with a PhD in Computer Science in March 2020. These days I work for Meta.

At UCSB, I was fortunate to work with Prof. Subhash Suri on some shortest path problems involving graphs and geometry. Please see the list of papers below for more details on my research. Prior to joining UCSB, I spent two amazing years at School of Computer Science, University of Waterloo (Link to Master's thesis) In past (2010-13), I have worked as a software Engineer at Emulation Division of Mentor Graphics. In distant past (2010), I had recieved my bachelors degree in Computer Science from IIT(BHU), Varanasi.
