Profile

I started as an undergraduate at the Department of Electronic and Electrical Engineering (EEE) at The University of Sheffield in September 1996. I was awarded a 1st class BEng in Electronic Engineering - Communications, and was fortunate to be given a full scholarship to pursue a PhD degree at EEE.

The PhD in Electronic Engineering significantly broadened my knowledge in Engineering and stimulated my desire to learn and research. In particular, I gained deep understanding of how optical and electronic device properties can be modified by carefully optimised semiconductor crystals. The ability to select different atoms to be combined in new semiconductor materials has led to many breakthroughs in transistors, lasers, solar cell and detectors.

EEE has provided a wonderful environment for me to explore fundamental engineering questions, advance research to generate lasting impacts and to share my experience with students and researchers. I have always felt at home because of the strong support from academics, when I was a student, and from colleagues across the department since I became an academic in 2003.

My career has progressed with great support from many great colleagues and students, whom I considered my “extended family”. The welcoming environment and strong research and teaching culture in EEE have helped to enrich my experience in work and in life. In February 2019 I was appointed Head of Department for EEE, a position of responsibility which I am very proud to take up.
