Dimosthenis Peftitsis was born in May 1985 in Kavala, Greece. He obtained the Diploma Degree with honours in Electrical and Computer Engineering from Democritus University of Thrace (Xanthi, Greece) in 2008. In his last year, he spent six months in ABB Corporate Research (Västerås, Sweden) writing his diploma thesis. In 2013, he received the PhD degree from KTH Royal Institute of Technology (Stockholm, Sweden).

Dimosthenis has been a Postdoctoral Researcher involved in the research on SiC converters at the Department of Electrical Energy Conversion, KTH Royal Institute of Technology (2013-2014). He has also worked as a Postdoctoral Fellow at the Lab for High Power Electronics Systems, ETH Zurich, where he was involved in research on dc-breakers for multiterminal HVDC systems (2014-2016).

In 2016, he joined the Norwegian University of Science and Technology in Trondheim, Norway, as an Associate Professor of power electronics at the Department of Electric Power Engineering. In 2022, he became full Professor.

His current research interests are:

WBG (e.g. SiC, GaN) power converters design for high-power and MV applications
