A/Prof PS Lee obtained his BEng (1st Class Honors) and MEng from the Department of Mechanical Engineering at the National University of Singapore and was a Senior Tutor with the same department from 1999 to 2001. He then proceeded to obtain his PhD degree from the School of Mechanical Engineering, Purdue University, West Lafayette, USA in 2007. His current research interests include microfluidics and microscale heat transfer, high performance thermal management techniques (in particular microchannel single- and two-phase cooling) and hybrid solar energy harvesting systems. His work were published in top international journals and widely cited. One of his papers won the International Journal of Heat and Mass Transfer Most Cited Papers Award for 2005-2008. In addition, he developed various novel and effective passive techniques for enhancing the heat transfer performance of microchannel heat sinks and mitigating the critical issues of hotspots and large temperature gradients in electronics devices and holds 2 US patents related to these efforts. He is also the recipient of various awards including the 2009 Tan Kah Kee Young Inventors Award, 2011 Asia Pacific Clean Energy Summit Top 10 Defense Energy Technology Solutions Award and the 2011 Institution of Engineers Singapore (IES) Prestigious Engineering Achievement Award.
