Biography

Morteza S. Alavi was born in Tehran, Iran. He received the B.Sc. and M.Sc. degree in electrical engineering from the Iran University of Science and Technology and University of Tehran, in 2003 and 2006, respectively, and his Ph.D. degree in electrical engineering from the Delft University of Technology (TU-Delft), Delft, The Netherlands in 2014. His main areas of research interest are designing RFIC for wireless and cellular communication systems as well as in the field of CMOS wireline transceivers. He has co-authored Radio-Frequency Digital-to-Analog Converter (Elsevier, 2016).

Mr. Alavi was the co-founder and CEO of DitIQ B.V., a local company which is developing energy-efficient, wideband wireless transmitters for the next generation of the cellular network. Since September 2016, he is an assistant professor in ELCA group at Delft University of Technology. Mr. Alavi serves as a reviewer for the Transaction on Microwave Theory and Techniques (MTT) and the Journal of Solid-State Circuits (JSSC). He was the recipient of the Best Paper Award of the 2011 IEEE International Symposium on Radio-Frequency Integrated Technology (RFIT). He was also the recipient of the Best Student Paper Award (2nd Place) of the 2013 Radio-Frequency Integrated Circuits (RFIC) Symposium. Very recently, his Ph.D. student won the Best Student Paper Award (1st Place) of 2017 RFIC Symposium held in Honolulu, Hawaii, USA.
