Brief Narrative

Rui Huang received a B.S. degree in Theoretical and Applied Mechanics from the University of Science and Technology of China in 1994 and a PhD degree in Civil and Environmental Engineering, with specialty in Mechanics, Materials, and Structures, from Princeton University in 2001. He joined the University of Texas at Austin as an Assistant Professor in September 2002 and was promoted to Associate Professor with tenure in 2008.

Dr. Huang's research interests are in the area of engineering mechanics with a particular emphasis on integrated materials and structures of small dimensions (from micro to nano scales). His research is motivated by practical applications in microelectronics, photonics, micro-electromechanical systems (MEMS), and emerging nano/bio-technologies. The objective of his research is to provide fundamental understandings of the mechanics in integrated material systems and to establish a scientific base for design, fabrication, and testing of such systems.
