Who am I? Wer bin ich? Moi, c'est qui?

Starting July 2012, I am joining the faculty of Dhirubhai Ambani Institute of Information and Communication Technology (DA-IICT), India as assistant professor. My new webpage is http://intranet.daiict.ac.in/~ajit_r.

I defended my PhD thesis in October 2010 in the Department of Computer and Information Science and Engineering at the University of Florida, Gainesville. My advisors are Anand Rangarajan and Arunava Banerjee. I have a bachelor's degree in computer engineering from the University of Pune, India, and a master's degree in computer science from McGill University, Montreal, Canada. I worked as a postdoctoral researcher at Duke University, Durham, North Carolina, from Jan 2011 to June 2012.
