Personal profile

Research Interests

Power semiconductor devices and power electronics

Efficient and reliable power and energy conversion

Batteries for automotive applications

Vision Statement

My research includes addressing issues associated with the functionality, efficient performance and reliability of power and photovoltaic semiconductor devices by means of modelling, simulation, design, fabrication and evaluation of novel concepts both in Silicon and wide bandgap materials such as Silicon Carbide and Gallium Nitride.

Biography

Neophytos received the Bachelor of Arts with Honours (BA Hons) in Electrical and Information Science (2008), the Master of Engineering (MEng) in Electrical and Electronic Engineering (2009) and the PhD in Power (2014) from the University of Cambridge, Cambridge, UK.

Currently he is a Lecturer in Electrical Engineering at the School of Computing, Electronics and Mathematics, Coventry University. He is also an associate member of the Faculty Research Centre for Mobility and Transport, Coventry University, and an Academic Collaborator at the High Voltage Microelectronics and Sensors Group, University of Cambridge.
