Biography

Professor Dan Sievenpiper joined the UCSD faculty in 2010. He received his BS in 1994 and his PhD in 1999 from UCLA, where he studied photonic crystals and periodic structures, and invented the high impedance electromagnetic surface. After graduation, Dan joined HRL (the former Hughes Research Laboratories) in Malibu, CA. During the following 11 years, he developed new electromagnetic structures, with an emphasis on small, conformal, tunable, and steerable antennas. Dan held a variety of technical positions at HRL, including serving as the director of the Applied Electromagnetics Laboratory. At UCSD, his research is focused on artificial media, and the integration of active electronics with electromagnetic structures and antennas to enable new capabilities. In 2008, Dan was awarded the URSI Issac Koga Gold Medal. In 2009, he was named as a Fellow of the IEEE. Since 2010, he has served as an associate editor of IEEE Antennas and Wireless Propagation Letters. He is also currently the chair of the IEEE Antennas and Propagation Society Administrative Committee on New Technology Directions. Dan has more than 70 issued patents and more than 60 technical publications.
