Hi! I'm Dennis, I'm a communications engineer by training, a software engineer by passion, and I currently work on providing connectivity to the entire planet Earth at Lynk in the Washington, D.C. Metro area.

Prior to my current position in industry, I was 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 under the supervision of David J. Love and Chih-Chun Wang.

My academic research broadly revolved around the field of wireless communications. In terms of research areas, I am generally interested in signal processing for wireless communications, multiple-input multiple-output (MIMO) communications, information theory, and related topics. I have a passion for implementation and experimentation with software-defined radios (SDRs): I was active in various SDR competitions throughout the years and I fundamentally believe that autonomous intelligent radio networks—a fusion between the advanced "traditional" networks we have today (think LTE, 5G NR, or IEEE 802.11) and the impressive inference & reasoning capabilities of modern artificial intelligence systems–are the next step in the evolution of wireless connectivity on this (and other) planet(s).

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 where there is fresh air.
