- Research Staff
I am a Research Associate in the Department of Computer Science and Technology, University of Cambridge. I completed my PhD from Indraprastha Institute of Information Technology, Delhi. During my PhD, I also worked as a visiting scholar at George Mason University, USA. I hold a M.Tech (2017) in Computer Science and Engineering from National Institute of Technology, Durgapur working with Mobile Computing and Networking Research Group and a B.Tech (2013) in Computer Science and Engineering from the Institute of Science and Technology, Guwahati. I have been a Student Researcher at ForkIT for the project Post Disaster Situation Analysis and Resource Management using Delay-Tolerant Peer-to-Peer Wireless Networks (DISARM) during the year 2016-17 . Between 2014 and 2015, I have worked as Assistant Project Engineer at IIT Guwahati for the project "Development of Text to Speech System in Assamese and Manipuri Languages" under the guidance of Prof. S.R.M.Prasanna.
