Welcome to my home page. I am currently working as a full Professor effective from 1 January 2023 in the Center for Security, Theory and Algorithmic Research (Department of Computer Science and Engineering) of the International Institute of Information Technology (IIIT), Hyderabad, India. I am also currently working as a Distinguished Adjunct Professor, with the Department of Computer Science and Engineering, College of Informatics, Korea University, Seoul, South Korea. I worked as a Visiting Research Professor in 2024, and also as a Visiting Faculty in 2022, at the Old Dominion University (ODU), Virginia, USA, with the Virginia Modeling, Analysis, and Simulation Center (VMASC).

"Successful people are not gifted; they just work hard, then succeed on purpose." -- G. K. Nielson
"If we knew what it was we were doing, it would not be called research, would it?" -- Albert Einstein
"If I had an hour to solve a problem, I'd spend 55 minutes thinking about the problem and 5 minutes thinking about solutions." -- Albert Einstein
"The three great essentials to achieve anything worthwhile are, first, hard work; second, stick-to-itiveness; third, common sense." -- Thomas A. Edison
“Life is like riding a bicycle. To keep your balance, you must keep moving.” -- Albert Einstein
"It's simply a matter of doing what you do best and not worrying about what the other fellow is going to do." -- John R. Amos
For prospective students:
I mainly work with full-time PhD students.
I am not currently working with part-time PhD students.
While working with me, I expect that research should be a student's primary intellectual activity.
