About me
I am currently working as a Research Scientist at GE Global Research, Bangalore, India. I completed my Ph.D. from the Department of Computer and Information Science and Engineering, at the University of Florida. My advisors were Arunava Banerjee and Anand Rangarajan. I hold a baccalaureate degree in computer engineering from the University of Madras, India and a master's degree in mathematics and in computer science from the University of Florida.
