Welcome to my electronic den. As you have no doubt guessed, the person staring at you from the picture above is me. This very basic Web page is intended to keep track of my current activities.


I am a CAD Research Scientist at Strategic CAD Labs, Intel Corporation. Prior to this, I was a Research Scientist at the Center for Information Assurance and Security, Department of Computer Science, University of Texas at Austin. I graduated with a Ph.D from the same department in December 2005.

This page is divided into the following sections.

I do not provide any guarantee regarding the accuracy of anything in this Web page; however, if you find any errors or have any other comment or criticism (or, for that matter, appreciation), I will appreciate if you let me know.


My chief research interest is in the formal verification, i.e., the use of formal mathematical analysis to ensure the correctness and security of of computing systems. My current focus is on developing scalable techniques for post-silicon verification of industrial designs. In the past, I have worked on developing formal analysis techniques for a slew of applications, including software correctness, concurrent protocol verification, formalization and verification of information flow properties, certification of behavioral synthesis transformations, and verification of analog and mixed signal designs. My work encompasses both mechanical theorem proving techniques and algorithmic decision procedures. While at UT Austin, I was a member of the UT Austin Automatic Theorem Proving Research Group. My Ph.D advisor was J Strother Moore, and a large chunk of my research, both during my Ph.D. and afterwards, has revolved around the ACL2 theorem prover that he has co-authored with Matt Kaufmann. I have also dabbled a bit into two other theorem provers, Coq and Isabelle. After moving to Intel, I have started focusing more on automated verification approaches based on SAT and SMT techniques and using Intel's Forte system. My other research interests include Model Checking, Distributed Systems, Algorithm Analysis, Complexity Theory, Logic, and Foundations of Mathematics.

The following project pages provide a flavor of some of the research areas that I have worked on. The projects are listed in no particular order. Note that the list of projects is not exhaustive: for a more comprehensive overview of my research activities, see my publications.

[Note: The project pages below are no longer maintained since I left UT Austin. I leave them here as a record of a snapshot of my activities circa 2011. But they have not been updated (beyond cosmetic changes) since.]

My research at UT Austin was funded in part by grants from the following projects. I gratefully acknowledge the support. The project pages above credit the individual fundings associated with each project.

Additional details about my research and professional colleagues are available from the following pages.

Many of the publications above have to do with ACL2. Such papers are also linked from the Web page “Books and Papers About ACL2 and Its Application” maintained by Matt Kaufmann and J Strother Moore. That Web page contains a comprehensive listing of (and links to) a number of books and papers written by several ACL2 users. If you are interested in the ACL2 and its applications, I strongly recommend that you visit the page.

I have compiled a list of interesting papers about verification of microprocessors and digital hardware designs here. If you are doing research in this area, I hope you find the list useful.

As a researcher, I find Dijkstra's three golden rules for successful scientific research very illuminating.


I co-taught the following classes at UT Austin. My teaching style has been significantly inspired by the Ten Commandments of Yale Patt.

Professional Services

The following list tracks my editorial and conference committee activities.

Jason Baumgartner, Ganesh Gopalakrishnan, Warren A. Hunt, Jr., and I maintain the FMCAD Mailing List. This list is intended to provide an open mechanism for researchers to communicate on topics related to the use of formal methods in computer-aided design. If you are interested in this area, I urge you to join the mailing list.

Warren A. Hunt, Jr. and I maintain the FMCAD Organization Home Page. FMCAD is a major conference, providing a forum for researchers to present cutting-edge research related to the use of formal methods in computer-aided design. FMCAD 2012 will be held in Cambridge, United Kingdom.

I am a Senior Member of IEEE, Professional Member of ACM, and Full Member of the Sigma Xi Scientific Research Society.


As you can see, I am thoroughly overworked (tongue in cheek) and have little time to indulge in other activities. When I do have time, I like to do the following. Note especially the third item. At some point in my past life, I used to love writing (non-technical) essays and poetry. I do not find time for that any more, mostly because I am lazy and that kind of work requires more mental exertion than I am prepared to execute. Well, that should tell you what I like most in my day-to-day life, namely “lolling in the sofa” doing nothing.
