Professor Stephen U. S. Choi passed away on Friday, January 18, 2013, after battling cancer. He was kind and generous colleague, and a gifted scientist. He will be sorely missed.
Dr. Choi joined the Department of Mechanical and Industrial Engineering at UIC in August of 2006 as a Research Professor. Dr. Choi received his Ph.D. in Mechanical Engineering from the UC, Berkeley, and was recently named a Fellow of the American Society of Mechanical Engineers (ASME). Prior to coming to UIC, Dr. Choi was at the Energy and Environment Division, at Argonne National Laboratory conducting research, primarily in advanced fluids. He was also Staff Scientist at Lawrence Berkeley Laboratory and a Nuclear Staff at Bechtel Power Corporation in San Francisco.
Dr. Choi’s work on advanced fluids culminated in the invention of nanofluids. He proposed the concept of nanofluids in 1993 and led the nanofluids team to develop stable nanofluids that showed high thermal conductivities. His team reported making the first nanotube-based nanofluids in 2001. He was the lead author of the first review article on nanofluids in the Encyclopedia of Nanoscience and Nanotechnology. His pioneering work created a new, active area of interdisciplinary research in the field of nanoscience and nanotechnology. The potential of nanofluids to revolutionize cooling technology generated great interest worldwide. The nanofluid work was recognized as one of the top research accomplishments by DOE’s Office of Basic Energy Sciences in 2002 and 2003.
Dr. Choi received the University of Chicago Distinguished Performance Award, the highest honor the University bestows on research scientists at ANL, for pioneering scientific achievements and outstanding leadership in nanofluids research. He is author or co-author of more than 100 technical publications in the areas of nanofluids, heat transfer, fluid mechanics, non-Newtonian fluid flow and heat transfer, thermal hydraulics, energy conservation and rheology.
