Background

Research Fellow - Jun 2016 to Mar 2017. Sponsored by Innovate UK, McLaren Automotive, Hofer Powertrains and Yasa Motors. Provided consultancy on the theory and implementation of wide bandgap (WBG) power semiconductor devices and modelled their heating and the heating of advanced electronic packaging materials in a high temperature capable motor controller when subjected to the provided high performance driving cycle data.

Research Fellow - xx to yy. High Temperature Converters Project, sponsored by Innovate UK, GE Aviation, Semelab, Ricardo, GaN Systems Semiconductors and Diamond Hard Surfaces. Worked with the industrial partners to select and evaluate the relative performance of candidate electronic materials for realising high temperature power electronic converter modules. Evaluated dozens of different candidate materials and WBG devices from around the globe using high temperature storage and thermal cycle testing up to 350 degC and analysed their time-dependent fatigue and material propoerty changes using indentation, electron microscopy (FIB/SEM/TEM/EDX,AFM) and laser inferometer, for example. Fabricated samples in semiconductor cleanroom including thin-film metal multilayers, substrate metal plating's and ohmic (metal to semiconductor) contacts.

Research Fellow - xx to yy. Low Carbon Vehicle Technology Project (LCVTP). Sponsored by Advantage West Midlands, Jaguar Land Rover, Tata, Ricardo, Mira, Zytek. Worked as part of a team of 2 researchers to model and experimentally measure the switching efficiency and heating of silicon carbide (SiC) schottky barrier diodes in electric motor controllers.

Research Fellow - xx to yy. Sponsored by Toyota Motor Corporation, Japan. Worked as part of a team of 5 researchers to model the switching efficiency and heating of power semiconductor devices in a converter driven by standard drive cycles and built a test bench capability for the Prius motor controller.
