Bio
Howdy! I'm Dennis, and I build radios for a living. I am currently employed as a Signal Analysis Engineer at the Jet Propulsion Laboratory.
Prior to that, I worked as a Telecom Software Engineer at Lynk and also 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 making our 5G and beyond-5G networks more flexible and secure. 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 lie 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.
In a life before graduate school & research, I studied electrical engineering and played Power Forward 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, or watching—and occasionally engaging in—sports somewhere with sufficiently fresh air and good vibes.
