I work for a major "Aerospace company" in Los Angeles, California doing RF systems engineering. Before that I was doing work on digital processors, which are pretty darn cool.
Before this I worked for a German company called EPCOS AG, based out of Munich, Germany. The company makes all types of passive E_lectricl P_arts and CO_mponent_S. Hence the highly ingenious name EPCOS. I was there for almost two years, designing dual band RF Surface Accoustic Wave (SAW) filters for American and European cordless phone systems.
Otherwise, prior to starting my first real full time job, I was going to graduate school at the University of Michigan. I did the Masters thing, TAed a course, and did a little research stuff on the side. The manuscript of the little paper that I wrote can be found below.

If you don't want to read the entire thing, don't worry, here is just the abstract. The conference was Computers in Cardiology. It was in Boston that year, and I was there. OOHHH yeah, baby.
Through grad school, there was also a little project Barun, Steve, and I did for our robotics class. I figured that I might as well toss it up here as well. It's a pretty good read (NOT). Check it out.

I also did a little work for Dr. Mike Lehmann at the university hospital on T wave amplitude and slope differences in men and women. Wrote a niffty little program in Matlab, which processes the heart beat data of a large group of subjects and offers an easy, transparent analysis this data.
Otherwise, I did a little project for my Time-Frequency/Wavelets class, where I tried to determine gender based on the wavelet decomposition of the ECG T-wave.

Lastly, I was a lab TA and also assistant head TA for EECS 270: Digital Design Class. Not only that, but I also maintained the web page. That's right everyone, Gregor does it ALL.
Just to throw the cherry on top of the ice cream, let me guide you to a last little paper that I was involved in during my undergraduate days. It was done at Georgia Tech at the Future Computing Environments Laboratory. Rob Orr wanted to try to identify people based on the Ground Reaction Force of their footstep. I helped him out in the early stages of the project, getting the literature researched and setting the initial experiment up.
