Hello, I am an assistant professor in Department of Computer Science at Indiana University Bloomington.
Previously, I earned my Ph.D. from Purdue University in December 2023, where I was co-advised by Prof. Dongyan Xu, Prof. Antonio Bianchi, and Prof. Z. Berkay Celik.
Before joining the Ph.D. program I was a researcher at Agency for Defense Development.
I am a system security researcher. I develop program analysis and formal method techniques to tackle security threats in systems.
My research is best represented by my extensive work on robotic vehicles (RVs).
I was working on automatically finding logic bugs, patching them, and verifying the patches in RV control software.
Currently, my efforts are dedicated to uncovering the root causes and formulating countermeasures against physical sensor attacks that target RVs.
I’m looking for highly motivated and ambitious students. If you are interested in working with me, please fill out this form.
