Subash Khanal

Subash was born in Kavrepalanchok, Nepal, in 1985. He received his M.Sc. (Tech) degree (2012) and D.Sc. (Tech) degree (2017) in the field of Radio Science and Engineering from Aalto University, Finland. During his Ph. D, he was involved in several projects with European Space Agency (ESA) where he studied characterization methods for Schottky diodes and dielectric materials for millimeter wave and terahertz applications. He joined Submillimeter Wave Advanced Technology (SWAT) group since August 2019 as a NASA Postdoctoral Fellow and is currently working with Dr. Goutam Chattopadhyay on design, fabrication and testing of submillimeter wave instruments and antennas for planetary and cometary applications.
