About me [CV]
I am an Assistant Professor at University
of North Carolina at Chapel Hill in the Department
of Computer Science. I have recently moved from
of Connecticut in the Department of
Computer Science and Engineering. My
research is at the intersection of Cyber-Physical
Systems, Formal Methods, Autonomy, Embedded and
Real-Time Systems, and Control Theory.
I am looking for bright and
motivated graduate and undergraduate students. Send
me an e-mail with your CV if you are interested.
I am currently working on developing
frameworks for integrating safe autonomy into
Cyber-Physical Systems. In my lab, we build, maintain,
and prove the safety of autonomous CPS.
In the recent past, I have contributed to developing scalable techniques for safety verification of linear hybrid systems. This technique (available here) requires a mere n+1 simulations for computing the reachable set of n dimensional linear system. We have also implemented new constraint propagation techniques and dynamic aggregation techniques for verification of linear hybrid systems (available here and here). This work has won the Best Paper Award at ARCH Workshop, 2017.
My PhD thesis was about "Dynamic
Analysis of Cyber-Physical Systems". I have developed
a tool that combines the scalability of simulations
with the correctness guarantees of formal verification
and applied it to analyze ALAS,
an alerting system for a parallel aircraft landing
protocol developed by NASA (details)
and powertrain control systems in automobiles (details).
In the past, I have worked on Probabilistic Systems, Automatic Test Input Generation, and Decision Procedures.
