James S. Langer

James S. Langer is a Research Professor of Physics at the University of California, Santa Barbara, where he has been affiliated since 1982. Previously, he served on the physics faculty at Carnegie Mellon University and was Director of UCSB's Institute for Theoretical Physics (1989-1995). His research focuses on theoretical condensed matter physics with emphasis on nonequilibrium phenomena.

Education:

• B.S. Physics, Carnegie Institute of Technology (now Carnegie Mellon University), 1955
• Ph.D. Mathematical Physics, University of Birmingham (UK), 1958 (supervised by R.E. Peierls)

Research Focus: Langer's work explores fundamental theories of nonequilibrium systems including kinetics of phase transitions, crystal growth mechanics, earthquake dynamics, deformation/failure in solids, dislocation theory, and glass transition phenomena. His recent publications develop shear-transformation-zone theories to explain plasticity in amorphous materials and polycrystalline solids.

Publication Trends: Recent articles (2011-2017) demonstrate consistent focus on theoretical modeling of material deformation mechanisms, particularly in amorphous and disordered systems. Key themes include dislocation-mediated plasticity, statistical thermodynamics of strain hardening, glass transition dynamics, and nonequilibrium behavior of driven materials.

Awards & Leadership:

• Marshall Scholar (1955)
• Oliver Buckley Condensed Matter Physics Prize (1997)
• President, American Physical Society (2000)
• Vice President, National Academy of Sciences (2001-2005)
• Inaugural Editor, Annual Review of Condensed Matter Physics (2008-2015)

Academic Contributions: Langer maintains active research collaborations evidenced through co-authored publications. While specific student advisees aren't listed, his career includes significant mentorship through leadership at the Institute for Theoretical Physics and ongoing research partnerships.
