Hello! I’m a PhD student studying electrical engineering at the University of Colorado Boulder. My general interests lie in applied electromagnetics, particularly in antennas, phased arrrays, and lenses.

I’m currently with the Antenna Research Group at CU, where I’m working on the design of unusual dielectric lenses for phased array applications. I previously worked on electrically small antennas for compact phased arrays, as well as work in the High Speed Digital Engineering Group at CU on high bandwidth conductive ink structures.

In my free time, I enjoy taking walks in the woods.

A copy of my resume is available here. I can be reached at edward@wawrzynek.com.
