Bildsten was then a research fellow at Caltech for three years, after which he accepted a faculty appointment at the University of California, Berkeley. Rising from assistant to associate professor, in both the physics and astronomy departments, he moved to UCSB in 1999.[3] In 2010, he was awarded the Wayne Rosing, Simon and Diana Raab chair in theoretical astrophysics. He was named director of the Kavli Institute, succeeding David Gross, in 2012.[4]
In addition to his university teaching and research, Bildsten has devoted significant effort to strengthening science and engineering education in grades 7–12. A member of the board of directors of Santa Barbara's Dos Pueblos Engineering Academy Foundation, he worked to raise $3 million in funding for a dedicated facility and to support math tutors.[5]
