Biography
Choi received his B.S. and M.S. in Mechanical Engineering from Seoul National University in Korea, and his Ph.D. in Mechanical Engineering from the University of California, Berkeley. He was a Senior Scientist and lecturer in the Department of Mechanical and Process Engineering at ETH Zurich before joining UNT in 2006. Choi also has served as a committee member on ASME K-15 committee and chaired/organized numerous workshops and conferences.
Research
Taeyul Theo Choi's research interests include thermal and fluid science in terms of micro and nanoscale. His recent research also includes acoustic wave propagation through functional nanomaterials. He has published more than 40 referred journal papers and his research is funded by a variety of funding agencies, including the National Science Foundation, industry and international funds.
Choi’s research group focuses on micro/nanoscale thermal transport phenomena. In specific, he is interested in thermal conductivity in 1-D (such as carbon nanotubes), 2-D (e.g., graphene), and 3-D material systems including biological cells. The cellular level temperature characterization revealed temperature rise during laser irradiation on a retinal pigment epithelium cells and through the thermal conductivity at cellular level, he discovered that the thermal conductivity of cancer cells is lower than that of normal cells. Here are a few topics of his research.

Cellular level thermal conductivity for early cancer detection
Nanoscale thermal characterization
Interfacial thermal resistance
Nanocomposite membrane for dehumidification application
Femtosecond laser material processing
