Senad Bulja (M’07–SM’12) received the B.Eng. (Hons.) and Ph.D. degrees from the University of Essex, Colchester, U.K., in 2002 and 2007, respectively. From 2007 to 2010, he was a Senior Research Officer with the School of Computer Science and Electronic Engineering, University of Essex, where he led the characterization effort of liquid crystals at microwave and millimeter-wave frequencies, and the development of liquid-crystal-based millimeter-wave devices. At present, he is Principal Scientist at Tyndall National Institute, in charge of creating a Radio Frequency (RF) Hardware research team. Previously, from 2010 until 2020, he was with Nokia Bell Labs, where he was Senior Research Scientist. There, he led the effort in the research and development of low-profile resonators and filters and the discovery of dielectric tunability of inorganic electro-chromic materials and RF switching capability of transition metal oxides. He is also CTO and founder of a Nokia spin-out, ArqKos, which focuses on high RF performance filters. He has authored/co-authored over 70 papers in international journals and conference proceedings and holds over 70 patents in the area of electromagnetics and wireless telecommunications. He is a recipient of many awards, such as the award for being Nokia’s top inventor and Best Innovation Prize from the European Space Agency. His current research interests encompass new tunable RF dielectric and optical media, RF filters, RF amplifiers, specialized antennas, complete RF transceivers and a plethora of RF passive and active devices (attenuators, couplers and phase shifters) up to 300 GHz. Dr. Bulja is a Fellow of IET and a Senior Member of the IEEE, https://drbulja.com/.
