Scientific research Throughout his career, Yang has conducted extensive research in the fields of mechanical, aerospace, civil, and structural engineering. He is known for his work on the
finite element method for plates and shells, as well as his contributions to
transonic computational
aeroelasticity, including
aircraft design and
flutter control. His research has also addressed
earthquake engineering, particularly in improving the
seismic design of
power plants. In addition, he has studied structural sensing and control under
seismic and
wind loads, and has contributed to the early investigation of meso-scale plasticity and deformation processes. His book,
Finite Element Analysis, has been widely adopted as an engineering textbook in many American universities and has been translated into Chinese and Japanese.
Purdue University Regarded as an expert in
aerospace structures,
structural dynamics, transonic
aeroelasticity, wind and earthquake
structural engineering, intelligent manufacturing systems, and
finite elements, He first joined the faculty as an assistant professor in 1969, before being elevated to the head of the
Purdue University School of Aeronautics and Astronautics, which he served for five years from 1980 to 1984. Yang was named the dean of the
Purdue University College of Engineering on July 1, 1984, a post he served for 10 years until his departure for UC Santa Barbara in 1994. In addition, he received the university-level Outstanding Undergraduate Teaching Award from Purdue University 12 times.
UC Santa Barbara After a seven-month search of over 150 applicants, Yang was named the fifth chancellor of the
University of California, Santa Barbara (UCSB) in March 1994. He began to serve as the university's chancellor on June 23, 1994. Yang was reported to have personally invited and recruited many researchers he believed possessed long-term scientific potential, promising them sufficient funding, new research facilities, and research teams, to improve UCSB's academic research capabilities and influence. Within the first 12 years of Yang's chancellorship, five UCSB scholars personally invited and recruited by Yang to the university faculty won
Nobel Prizes between 1998 and 2004. In 1997, Yang flew to New Jersey and persuaded
David Gross to join the UCSB faculty, agreeing to meet all four of Gross's conditions for his physics research; Gross later received the 2004 Nobel Prize in Physics. Yang spent five years to recruit the well-known cognitive neuroscientist
Michael Gazzaniga to UCSB, with promises in funding and research facilities. Yang has guided 57 Ph.D. and 23 M.S. recipients. In addition to his role as chancellor, he is also a professor of mechanical engineering at UC Santa Barbara. He continues to teach an undergraduate engineering course each year. He currently supervises three Ph.D. students with support from
National Science Foundation grants. He is also a co-principal investigator for the
Mathematics, Engineering, Science Achievement (MESA) program of the University of California. On August 14, 2024, Yang announced that he would step down as the university's chancellor at the end of the 2024–2025 academic year, while continuing to serve as a professor in the Department of Mechanical Engineering at the
UC Santa Barbara College of Engineering. With more than 31 years in office, Yang is the longest-serving chancellor in the history of the University of California. On June 16, 2025, UC president Michael Drake named David Marshall, the then-provost of UC Santa Barbara, as the interim chancellor, effective July 15. ==Boards and committees==
