Spartak Gevorgian received the M.S. degree in radioelectronics from the Yerevan Polytechnic Institute, Yerevan, Armenia, in 1972, and the Ph.D. and Dr.Sci. degrees from the Electrotechnical University, St. Petersburg, Russia, in 1977 and 1991, respectively. From 1972 to 1993, he held different research and teaching positions with the Yerevan Polytechnic Institute and the Electrotechnical University. From 1993 to 1998, he held research positions with Chalmers University of Technology, Göteborg, Sweden. Since 1998, he has been a Professor with Chalmers University of Technology. Since 1996, he has also worked part time with Ericsson Microwave Systems AB (currently Ericsson AB), Mölndal, Sweden. He has authored or coauthored over 300 papers and conference presentations. He holds over 30 patents/patent applications. His research interests are physics, design, and experimental investigation of microwave devices and components based on ferroelectrics, silicon RF integrated circuits (RFICs) and monolithic microwave integrated circuits (MMICs), microwave photonic devices (optically controlled components), and modeling of passive coplanar components based on conformal mapping.
