Welcome to my home on the Web! I try to keep this page updated with professional and academic information as well as some personal content.

I currently work on flight telecom systems at NASA's Jet Propulsion Laboratory. Prior to that, I worked as a telecom software engineer at Lynk and spent some time as a postdoc in the Bradley Department of Electrical and Computer Engineering at Virginia Tech, where I worked with Jerry Park on next-generation WiFi and 5G security topics. Before that, I completed my Ph.D. at the School of Electrical and Computer Engineering at Purdue University working with David J. Love and Chih-Chun Wang.

My research interests are somewhere at the intersection of communication theory, signal processing, and computer engineering. I have a passion for implementation and experimentation with software-defined radios: I was active in various SDR competitions throughout the years, I get to play with them at my day job, and I sometimes even find enough time for some freelance hacking at night.

For my undergraduate degree, I studied electrical engineering while playing the power forward position at Tennessee Tech University. Prior to that, I played both forward positions in Nürnberg as well as in Munich, my beautiful home town. In the rare case where I am not fighting with some tricky code in Emacs, you can usually find me out camping, hiking, snowboarding, or at the gym.
