Biography

Hjalti H. Sigmarsson received the B.S.E.C.E. and M.S.E.C.E., degrees in 2003 and 2005 from University of Iceland, Reykjavik and Purdue University, West Lafayette, IN, respectively. He completed the Ph.D. degree in Electrical and Computer Engineering from Purdue University, West Lafayette, IN, in May 2010. He was a postdoctoral research associate in the IDEAS (Integrated Design of Electromagnetically-Applied Systems) Laboratory at Purdue University from 2010 to 2011. His primary focus was on advancing the state-of-the-art tunable filter technology for ultra-sensitive receivers. In January 2012, he joined the faculty at the School of Electrical and Computer Engineering at the University of Oklahoma. His current research interests include: Reconfigurable RF and microwave hardware for agile communications, measurement, and radar systems, spectral management schemes for cognitive radio architectures, and advanced packaging utilizing heterogeneous integration techniques.

Dr. Sigmarsson is a senior member of the IEEE and an active member of the Microwave Theory and Techniques Society (MTT-S) and the International Microelectronics and Packaging Society (IMAPS). He is a member of the IEEE MTT-S Technical Committee 5: Filters. He was an associate editor for the IEEE Transactions on Microwave Theory and Techniques 2022-2025, an associate editor of the IEEE Microwave and Wireless Components Letters 2018-2022, and the Editor-in-Chief for the IEEE MTT-S electronic newsletter 2022-2025. In 2019, he was the General Chair of the IEEE Wireless and Microwave Technology Conference (WAMICON). He has served as a reviewer for numerous journals and conferences, including Transactions on Microwave Theory and Techniques, Microwave and Wireless Components/Technology Letters, Microwave Magazine, Journal of Microwaves, Transactions on Antennas and Propagation, Antennas and Wireless Propagation Letters, Open Journal of Antennas and Propagations, Transactions on Circuits and Systems, Journal of Microelectronics and Electronic Packaging, Journal of Electromagnetic Waves and Applications, IEEE International Microwave Symposium, IEEE WAMICON, IEEE Research and Applications of Photonics in Defense, IEEE Radio Wireless Week, EuMA European Microwave Conference, and the IEEE Vehicular Technology Conference.

Dr. Sigmarsson was a member of a team that received recognition for outstanding technical contribution to Phase I of the DARPA Analog Spectral Processors (ASP) program in 2008. He was awarded the best paper of the IMAPS 2008 41st International Symposium on Microelectronics and the outstanding student paper of the IMAPS 2009 42nd International Symposium on Microelectronics. He was also awarded the best paper of the Microwave and RF Applications session at the both the 2008 and the 2009 IMAPS International Symposium on Microelectronics. In 2015, Dr. Sigmarsson was awarded the Air Force Office of Scientific Research (AFOSR) Young Investigator Research Program (YIP) to pursue his research on reconfigurable RF electronics using phase-change materials. In 2018, Dr. Sigmarsson was named the recipient of the Gerald Tuma Presidential Professorship. He was awarded the 2021 OU Graduate College Graddy award for his outstanding support of graduate education. In 2026, he was appointed the Director of Research for the Advanced Radar Research Center.
