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.

News

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.

Research

My chief research interest is in trustworthy computing, i.e., making sure that our computing systems behave reliably, securely, and according to specification. My work brings in techniques from synthesis, architecture, system design, security, prototyping, and verification. In most recent work, I have been focusing on techniques for security architecture, synthesis, and validation; hardware/firmware/software codesign; design-for-resilience techniques for hardware/software systems; and post-silicon readiness and validation streamlining for System-on-Chip designs. I have also been looking at future computing systems, e.g., wearables, and Internet-of-Things, and trying to understand how the security, resilience, and validation problems change in that regime.

In my past life, I worked on formal verification. I focused on developing scalable domain-specific strategies for verifying 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. Much of this work married mechanical theorem proving with automated decision procedures. My research at UT Austin was sponsored by NSF, DARPA, and SRC, and found application in the verification tool-flow of a number of companies including AMD, Freescale, Galois, IBM, Intel, and Rockwell-Collins.

After moving to Intel, while I still sometimes use formal methods (e.g. with SAT and SMT solvers, Intel's Forte system, and theorem proving), I have developed a deep appreciation for semiformal methods and dynamic techniques. I have also learned to see verification as one component in the scheme of a larger collection of methods to ensure correctness and resiliency. My current work therefore focuses on marrying verification and validation techniques with resiliency infrastructures based on architecture and synthesis. Such combination can be incredibly powerful, and provide promising approaches to develop trustworthy designs for complex functional, security, and power-performance requirements. I believe they will be even more important in developing trustworthy and secure computing systems in the future, with wearables, fashionable implants, and IoTs.

My other technical interests include Distributed Systems, Algorithm Analysis, Complexity Theory, Logic, and Foundations of Mathematics.

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

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


Teaching

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.

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


Personal

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.
