About me [CV]

I am an Assistant Professor at University of Connecticut in the Department of Computer Science and Engineering.  My research is about developing scalable approximation and abstraction techniques for verifiying high dimensional CPS with complex software.


I am looking for bright and motivated graduate and undergraduate students. Send me an e-mail with your CV if you are interested.


My PhD thesis was about "Dynamic Analysis of Cyber-Physical Systems". I have developed C2E2, 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.


News:


  • Chuchu Fan presented our paper "Automatic Reachability Analysis for Nonlinear Hybrid Models with C2E2" at CAV 2016. Feel free to try our tool C2E2 for verifying nonlinear hybrid systems such as lane changing systems and C-Elegans biological systems.
  • Presented a paper titled "Parsimonious, Simulation Based Verification Of Linear Systems" at CAV 2016. Check out the new algorithm which verifies an n-dimensional linear system using a mere n+1 simulations here.
  • Presented a paper titled "Analyzing Real-Time Linear Control Systems Using Software Verification" at RTSS 2015. Find out about our new technique to verify linear control systems in presence of real time scheduler here.
  • I have moved to UConn CSE Department.
  • Join work with Chuchu Fan, Sayan Mitra, and Mahesh Viswanathan received the Most Promising Benchmark Result sponsored by Robert Bosch at ARCH Workshop, conducted as part of CPS Week 2015.



Previously:


I was at University of Illinois at Urbana Champaign for my graduate studies. My PhD thesis was supervised by Prof. Mahesh Viswanathan and Prof. Sayan Mitra. I obtained my B.Tech from Indian Institute of Technology Guwahati. I was an intern at SRI International in the Computer Science Laboratory in Summer 2012 and at NEC Labs America in the System Analysis and Verification Group in Summer 2011, and at Verimag in the Timed and Hybrid Systems Group under the supervision of Dr. Oded Maler in Summer 2008.
