Performance Modeling, Analysis, and Design (using Economics, Game Theory, Algorithms, and Mathematical Optimization) of Cyber-Security, Privacy, and Communication Networks
I am a Research Scientist at USC's Viterbi School of Engineering. I am associated with the school's Electrical Engineering and Computer Science departments. I graduated with a Ph.D from the Department of Computer Science at USC in Fall 2014. My thesis advisors were Professors Leana Golubchik and Konstantinos Psounis. For my PhD, I also collaborated with Professor Pan Hui of the Hong Kong University of Science and Technology. My major research interest lies in the area of cyber-security, privacy, and communication networks - especially performance modeling aspects of these using economics, game theory, algorithms, and mathematical optimization, with the end goal of making cyber-security and privacy as robust as possible, and improving/optimizing network performance. I also have a minor research interest in applied machine learning. During my PhD, I was a recipient of the prestigious Provost Fellowship at USC. As a PhD student at USC, I have held visiting research positions at Princeton University and Deutsch Telekom Research Laboratories, Germany. In the past, as an undergraduate and as a masters student, I have held research positions at Massachusetts Institute of Technology, National University of Singapore, University of California, Indian Institute of Technology, Kharagpur, India, Indian Institute of Management, Calcutta, India, and Center for TeleInfrastruktur, Aalborg University, Denmark. My Erdos number is 4. In my spare time (not that much nowadays :)) I do international travel, listen to music, watch movies, swim, and play/watch cricket and soccer. I also have a deep interest in Indian philosophy.
My Current Research - Problem Types, Goal, and Tools
I am an applied theory guy currently interested in the performance modeling/analysis of (i) security and privacy in networked and distributed systems (e.g., Internet, social networks, IoT and cyber-physical systems), and (ii) resource management in multi-tenant cloud and ad-driven video streaming systems. My primary research goal is two fold: (a) revealing fundamental insights into the efficient and/or secure design of communication systems by holistically integrating the economics, technical, game theoretic, optimization, learning, and psychological aspects of a research problem, and (b) realizing in practice, the efficient design of communication systems, using computationally efficient tools and tools from both, theoretical as well as experimental economics. More specifically, I do inter-disciplinary research (both fundamental and applied) that lies at the boundary of information security, applied and experimental economics, game theory, algorithms, stochastic processes, network science and graph theory, systems optimization, and applied machine learning. An example of such research is my Ph.D problem, where I investigated the important role of cyber-insurance markets in achieving a robust level of cyber-security, which is currently not present in the Internet due to several techno-social-economic constraints. In this regard, I hypothesized the use cyber-insurance as being an efficient tool that can alleviate these constraints and jointly satisfy the major parties affecting the level of cyber-security today, consequently leading to improved cyber-security. To prove my hypothesis, I had to solve hard problems that required the use of interdisciplinary tools from economics, game theory, network science, and mathematical optimization. Though this proved to be a great challenge for me, at the same time it gave me lot of fun. [My PhD Thesis, My PhD Defense Talk]

I love to travel. Life is boring without it!!!. I consider myself immensely lucky to have travelled to various parts of the world for both, academic as well as for holidaying purposes, at a young age. I generally make short yearly trips with friends, and really enjoy and relish the culture, food, nature, and monumental architecture in all the countries I visit. Listed below are the countries I have visited (airports not included :) ).
Asia: Singapore, Japan, Hong Kong, Thailand, Malaysia
North America: USA, Canada
Europe: Germany, Austria, Czech Republic, France, Russia, Switzerland, Italy, Vatican City, Holland, Belgium, Denmark, England, Sweden, Finland, Norway, Spain, and Portugal
