Dr. Vishal Jagtap

Head of Group


Vishal S. Jagtap received the Bachelor of Technology (B.Tech) degree in Engineering Physics from Indian Institute of Technology, Bombay, India, the M.Sc. degree in photonics and optoelectronic devices jointly from the University of St. Andrews, St. Andrews, Scotland, and Heriot-Watt University, Edinburgh, Scotland, and the Ph.D. degree worked on the development of instrumentation for thermal imaging arrays based on superconducting and semiconducting YBaCuO compound bolometers from the University Pierre et Marie Curie (UPMC), Paris, France, in 2009.

From 2006 to 2009, he was a Marie Curie Fellow at the Paris Electrical Engineering Laboratory (LGEP-Supélec), Gif-sur-Yvette, France. From 2009 to 2012, he was with the Laboratory of Photonics and Nanostructures (LPN-CNRS), Marcoussis, France. In 2012, he joined the Laboratory of Quantum materials and Phenomena (LMPQ), Paris, France. From 2016 to 2017, he was with the Rheinisch-Westfaelische Technische Hochschule (RWTH), Aachen, Germany. From 2018 to 2023, he was with the Institute for High-Frequency and Communication Technology, University of Wuppertal, Wuppertal, Germany. His research interests include silicon-integrated THz optoelectronic transceivers for sensing, imaging, spectroscopy, and communications applications.
