Welcome to Chittabrata’s Homepage!

I am a senior doctoral student in the Computer Science Department of the University of Cincinnati (UC), Ohio. My dissertation advisor is Professor Dharma Agrawal. Before joining UC, I was a Senior Research Fellow of Council of Scientific and Industrial Research (CSIR), New Delhi, India for a year. I have completed M.S. in the Electrical and Electronics Communications Engineering Department at the Indian Institute of Technology (I.I.T.), Kharagpur, India.

Currently I am looking for post doctoral fellowship in a dynamic research group of an esteemed university.

I can be reached at ghoshc@email.uc.edu, chitta.ghosh@ieee.org
