Brief Biography

Adekunle joined Durham University as the Principal of Trevelyan College and Professor of Physics in January 2020. He graduated with a First Class Honors Degree in Physics from the University of Ilorin, Nigeria (1990), MPhil (Microelectronic Engineering and semiconductor Physics), and Ph.D. degrees from the University of Cambridge, in 1993 and 1996, respectively. He was elected a Junior Research Fellow at Trinity College, the University of Cambridge in 1996. He then worked as a Senior Research Engineer at the Data Storage Institute, Singapore in 1997, before returning to Cambridge to take up his fellowship at the Nanoscale Science Laboratory. He joined the Department of Electrical & Computer Engineering, National University of Singapore (NUS) as an Assistant Professor in 2000. He was promoted to Associate Professor with tenure in 2006 and Full Professor in July 2012. He was the founding Master of the Ridge View Residential College at NUS.

His research focuses on the fundamental understanding and exploration of nanomagnets in non-volatile memory technologies. He has conducted pioneering research work in the field of nanomagnetism. He has won many awards including being named one of the top 100 young innovators in the world by TR100, an award-winning MIT magazine on technology. In 2013 he was selected Institute of Electrical and Electronic Engineering Magnetics Society Distinguished Lecturer. Adekunle is a Fellow of the American Physical Society, Fellow of the Institute of Physics, Fellow of the Institute of Nanotechnology, and a Royal Society Wolfson Fellow.
