Curriculum Vitae

Research Motto: In theory, there is no difference between theory and practice. But, in practice, there is.

I am a second year PhD student under Prof. Abhishek Chandra in the Computer Science Department at the University of Minnesota-Twin Cities. I also collaborate with Prof. Ramesh Sitaraman at University of Massachusetts, Amherst. Broadly, I am interested in Distributed Systems and its application in Data Analytics and Machine Learning. Currently, I am working on problems related to Geo-distributed Streaming Analytics and also looking to apply machine learning based techniques in systems.

I graduated in 2014 with a Bachelors in Computer Science from BITS-Pilani, India. At BITS-Pilani, I was a part of Advanced Data Analytics and Parallel Technologies Lab, where I worked on parallel and distributed algorithms for data mining.
