My main research interest is on optimization for NP-Hard problems, with a focus on problems relevant to VLSI CAD. I am also actively working on cryptography and biology-related topics.

I'm currently the Past Chair of the ACM Special Interest Group Governing Board, and was a member of the ACM Executive Committee and ACM Council. I'm also a past chair of ACM/SIGDA. Over the years, I've been on the technical program committees, steering committees, and organizing committees of DAC, ICCAD, ASPDAC, DATE, ISPD, and GLSVLSI, as well as an associate editor for IEEE Transactions on Computer Aided Design (TCAD) and ACM Transactions on Design Automation for Electronic Systems (TODAES). I've been a member of ACM since 1986.  In 2015, I received the SUNY Chancellor's Award for Excellence in Professional Service.

I'm the faculty advisor for the ACM Student Chapter at Binghamton; our team went to the ICPC finals a few years ago (woot!), just like I did when I was an undergrad (woot woot!).

In my spare time, I hack on iOS apps. Some of them are music related.

VLSI CAD Software

Most of my early research has focused on integrated circuit design. The feng shui placement tool, the vaastu placer, and the chi router have been put on the back burner.

But if you need a sequence pair floorplanner that runs on an iPhone, there's an app for that. I spent a sabbatical year in Japan, working in a research group with Profs. Kajitani, Nakatake, and Murata, the sequence pair pioneers!

Medical Software
In collaboration with Dr. Joshua Steinberg (a practicing physician), a number of medical reference apps were developed as part of CS441/580. These are intended for physicians, but you can check them out if you like. Kudos to the students who did the hackery! And while it's not medical related, an app from a prior offering of CS441 is available in iTunes; check out Blooper, from Aris Agdere.

Algorithms and Optimization
Check out the Computational Complexity app in the iTunes store; it's a quick introduction to Big-O complexity, and implements a variety of sorting algorithms to drive home the run time impact of using different methods. The app can generate random data for sorting, or data that is either sorted in order, or in reverse order.

Next Generation Cinema
I've collaborated with Prof. Monte McCollum from the Binghamton Cinema Department, to create a hybrid cinema experience. The experimental film "In A Free Sound Field" is meant to be played on a main projection screen, while audience iPhones are synchronized to play video and sound. Want to try it out? The film is available for the Apple TV, and the audience portion is in the iTunes Store. You can also catch the film at a number of film festivals where it is being exhibited.
