About Me

I am an Assistant Professor in the Department of Computer Science and Engineering at Pennsylvania State University. Prior to joining Penn State in fall 2020, I worked as a postdoc at Purdue University from where I received my Ph.D. in fall 2018. I received the NSF CAREER Award from the National Science Foundation (NSF) and the DARPA Young Faculty Award (YFA) from the Defense Advanced Research Projects Agency (DARPA) in 2022.

My research interest broadly lies in the areas of network and systems security. I lead the Systems and Network Security (SyNSec) research group and I am incredibly grateful to work with the students who are smarter than me. Our group focuses on improving the security and privacy of the design and software implementations of emerging networks and complex systems. We take a holistic approach to fundamentally enhance the security investigation of a system from the ground up, i.e., starting from analyzing designs, evaluating implementations, monitoring the runtime, and building verified/high-assurance defenses. As part of this process, we combine theory and practice by drawing inspiration from formal methods, program analysis, software testing, signal processing, and cryptography.

Our research results have led to a number of changes in the design of 4G and 5G cellular standards. In addition, our work has been discussed by the Federal Communication Council (FCC)  as well as covered by more than 100+ media outlets worldwide, including the New York Times, Forbes, The Washington Post, ACM Technews, and MIT Technology Review. The software artifacts from my research group have also been made open-source.
