Georges Pavlidis (Assoc)

Dr. Georges Pavlidis is a guest researcher associate in the Physical Measurement Laboratory. In 2022, he joined the Department of Mechanical Engineering at the University of Connecticut as an Assistant Professor. Prior to that, he was an NRC Postdoctoral Researcher in the Nanoscale Spectroscopy Group. He earned his M.Eng in Mechanical Engineering from Imperial College London in 2013 and his M.S., Ph.D. degree in Mechanical Engineering from the Georgia Institute of Technology in 2018. 

Dr. Pavlidis’ research focuses on developing new technology for solving today’s big data, energy, medical, space and quantum engineering challenges. His plan is to develop novel methods which will reveal complex processes that occur on the nanoscale. Examples of his research range from studying how heat is transferred in wireless devices to understanding the failure mechanisms in neuromorphic devices. By doing so, Dr. Pavlidis aims to improve the efficiency and performance of the next generation radio frequency (6G+) and power electronics (electric vehicles). His future research interests include monitoring the degradation in high performance systems as well as understanding the thermal properties of 2-D materials with outlook to quantum technologies.
