### Biography

Ioan E. Lager was born in Brasşov, Romania, on September 26, 1962. He received the M.Sc. degree in electrical engineering from the Transilvania University, Brasşov, Romania, in 1987, the Ph.D. degree in electrical engineering from the Delft University of Technology, Delft, the Netherlands, in 1996, and a second Ph.D. degree in electrical engineering from the Transilvania University in 1998.

He successively occupied research and academic positions with the Transilvania University and the Delft University of Technology, where he is currently Associate Professor. In 1997, he was Visiting Scientist with Schlumberger-Doll Research, Ridgefield, CT, USA. He has a special interest in bridging the gap between electromagnetic-field theory and the design, implementation, and physical measurements of wireless systems. His research interests cover computational electromagnetics and antenna engineering, with an emphasis on pulsed-field electromagnetic propagation and nonperiodic (interleaved) array antenna architectures.

Dr. Lager is active in several antenna engineering European networks, primarily in the “VISTA” COST Action.
