I am a Professor in the School of Computing and Information (SCI created in 2017) in the University of Pittsburgh. I did my MS in Computer Science and PhD in Computer Engineering degrees from Purdue University in 1998 and 2003, respectively. Before coming to the USA for the graduate studies, I was a Lecturer of Computer Science and Engineering in the department of CSE at Kathmandu University. I finished my BE in CSE degree from Motilal Nehru National Institute of Technology, India in 1993 under the Colombo Plan scholarship. I am from Kathmandu, NEPAL.
