Desmond Loke received BA in Electrical Engineering from National University of Singapore in 2008. He pursued his PhD at the Department of Electrical and Computer Engineering in NUS, and Department of Chemistry in University of Cambridge, where he worked on the topic of computer simulation and experimental study of the fast transformation for phase-change materials and devices between 2008 and 2012. At NUS and Cambridge, he has pioneered the control of crystallization kinetics of a phase-change material by pre-organizing atoms using a weak electric field, which has allowed the phase-change memory to achieve sub-nanosecond write speeds. In 2013, Desmond was awarded a postdoctoral fellowship from Singapore University of Technology and Design and Massachusetts Institute of Technology to start his independent research. Loke attended the Harvard University as a researcher in 2014. Desmond joined the SUTD faculty in 2015 as assistant professor in the Department of Science, Mathematics and Technology. His research is aimed at understanding the origin of behaviors of novel materials, and by using these effects, design and enable new memory and bioelectronic devices for next generation artificial intelligence (AI), fifth-generation wireless (5G) and medical technologies (MedTech).
