ABOUT ME

Dr Jennings obtained his PhD in Physical Chemistry from the University of Bath, United Kingdom in 2009. From 2009 to 2014 he worked as Research Fellow and then Senior Research Fellow in the Department of Materials Science and Engineering at the National University of Singapore. His research to date has included characterization and modelling of mesoscopic solar cells, redox flow Li-ion batteries, and electrochromic devices. In mid-2014 he was appointed as Lecturer in Applied Physics at Universiti Brunei Darussalam. Dr Jennings obtained his PhD in Physical Chemistry from the University of Bath, United Kingdom in 2009.
