Dr. Ghalichechian joined the Georgia Institute of Technology as an Assistant Professor in August 2021. Prior to joining Georgia Tech, he was an Assistant Professor at The Ohio State University (OSU), Columbus, from 2017 to 2021. During this period, he established the RF Microsystems Laboratory with research in the area of millimeter-wave antennas and arrays.

Dr. Ghalichechian received his B.S. in Electrical Engineering from Amirkabir University of Technology, Iran in 2001. He received his M.S. and Ph.D. in Electrical Engineering from the University of Maryland-College Park in 2005 and 2007, respectively, with research focused on electrostatic micromotors. From 2007 to 2012, he was with the Research Department of FormFactor, Inc. (Livermore, California) as a Senior Principal Engineer. During this period, he helped design and develop microsprings for advanced probe cards used in testing memory and SoC devices. Dr. Ghalichechian joined the Department of Electrical and Computer Engineering and the ElectroScience Laboratory at OSU as a Research Scientist in 2012. From 2016 to 2017, he held a Research Assistant Professor position at OSU.

Prof. Ghalichechian is currently an Associate Editor of the IEEE Antennas and Wireless Propagation Letters (AWPL). He is a recipient of the 2018 College of Engineering Lumley Research Award at OSU, 2019 NSF CAREER Award, 2019 US Air Force Faculty Summer Fellowship Award, and 2020 ECE Excellence in Teaching Award at OSU.
