Dr. James G. Berryman

 

Dr. Jim Berryman received his Ph.D. in physics from the University of Wisconsin in 1975.  He subsequently worked in the oil industry, at the Courant Institute NYU, and at Bell Labs, before moving to California in 1981.  He was then a Physicist for 25 years at the Lawrence Livermore National Laboratory in Livermore, CA.  He is currently a Geological Senior Scientist in the Earth Sciences Division at the Lawrence Berkeley National Lab in Berkeley, CA.  Jim received the ASCE Maurice Anthony Biot Medal for his work in poroelasticity in 2005.  Besides his work on poroelasticity, he has also worked extensively on effective medium theories of heterogeneous media, inverse problems for imaging of heterogeneous media, and time-reversal acoustics and electromagnetics for applications to imaging, identification, and communications.  He is a member of the American Physical Society, the Society of Exploration Geophysics, and the American Geophysical Union.
