Biography

Lei Zhou is a Ph.D. candidate in the ELCA research group at Delft University of Technology since January 2022. 

She received her BSc degree in Electrical and Electronic Engineering from Huazhong University of Science and

Technology, Hubei, China, in 2013 and M.Sc. degree in Microelectronics from Delft University of Technology,

Delft, the Netherlands, in 2016. Before embarking on her PhD study journey, she worked as an RFPA application

engineer in Ampleon, the Netherlands. Her research activity primarily focuses on efficient and broadband transmitters

for 5G base station applications.
