Rob is currently an Assistant Professor at the Singapore University of Technology and Design (SUTD), where he runs the Advanced Chalcogenides Technologies and Applications Lab (www.ACTALab.com). Rob’s research interests are focussed on designing chalcogenides and applying them to applications in electronics, photonics, and data storage. Prior to joining SUTD Rob received his PhD from from the Optoelectronics Research Centre at the University of Southampton, spent 3.5 years at the Japanese national institute for Applied Industrial Science and technology (AIST) as a JSPS postdoctoral fellow, and one year at the Institut de Ciencies Fotoniques (ICFO), Barcelona. Rob’s research has been awarded a number of prizes including the Westminster medal and the AIST best paper award.
- PhD from the Optoelectronics Research Center, University of Southampter, UK (2003-2007)
- MPhys (Master of Physics) degree from the University of Bath, UK, (1998-2002)
