[New] I will be joining the department of Computer Science and Engineering at IIT Kanpur as an Assistant Professor in the fall of 2015. This webpage will be discontinued shortly after I join. Please visit my other [homepage] for continued updates on my research.

I am a postdoctoral Research Fellow working with the Machine Learning and Optimization group. Previously I was a doctoral student at the Indian Institute of Technology Kanpur where I was fortunate to have been jointly advised by Prof. Harish Karnick and Prof. Manindra Agrawal. I did my bachelor studies from the same institution as well.

I am interested in theoretical and applied aspects in machine learning - presently I am interested in topics such as online learning, multi-armed bandits and kernel learning techniques. I also maintain an avid interest in learning theory, data streaming algorithms, geometry and cognitive science.

I maintain a separate homepage containing details about my research and contact information at the following URL (note that this link resides in a different domain): [my homepage].

Details of some of my recent publications can be found below.
