Peter H. Aaen (Senior Member, IEEE) received the B.A.Sc. degree in engineering science and the M.A.Sc. degree in electrical engineering from the University of Toronto, Toronto, ON, Canada, in 1995 and 1997, respectively, and the Ph.D. degree in electrical engineering from Arizona State University, Tempe, AZ, USA, in 2005. He was the Manager of the RF Division, RF Modeling and Measurement Technology Team, Freescale Semiconductor, Inc., Tempe, AZ, USA, a company which he joined in 1997, and the Semiconductor Product Sector, Motorola, Inc., Pheonix, AZ, USA. In 2013, he joined the Faculty of Engineering and Physical Sciences, University of Surrey, Guildford, U.K., where he was a Reader of microwave semiconductor device modeling. He was also the Director of the Nonlinear Microwave Measurement and Modeling Laboratory, a joint University of Surrey/National Physical Laboratory, and the Director of the National Physical Laboratory, Teddington, U.K. In 2019, he joined the Colorado School of Mines, Golden, CO, USA, as a Professor and the Head of the Electrical Engineering Department. He has coauthored the book Modeling and Characterization of RF and Microwave Power FETs (Cambridge University Press, 2007). His areas of expertise include calibration techniques for microwave measurements, the development of package modeling techniques, and the development of passive and active compact models for the design of microwave power transistors and integrated circuits (ICs). Dr. Aaen served as an Executive Committee Member and the Vice-President for the Automatic RF Techniques Group and formerly was the Chair of the IEEE Technical Committee (MTT-1) on Computer-Aided Design. He is a member of the Microwave Theory and Techniques and Electron Device Societies.
