Dr. Michael Commer is an affiliate scientist (retiree) at Lawrence Berkeley National Laboratory, Energy Geosciences Division. His interests include large-scale, multi-dimensional, inverse and forward modeling problems arising in exploration and environmental geophysics, numerical methods on distributed computing platforms, accelerated hardware computing, and electromagnetic geophysics. He has over 10 years of experience in numerical programming, geophysical (joint) imaging and modeling methods. Dr. Commer started his career at LBNL in 2004 as a postdoctoral scientist, supported through a Feodor-Lynen fellowship by the German Alexander-von-Humboldt foundation. He graduated in 2003 at the University of Cologne (Germany). His Ph.D. focused on three-dimensional time-domain electromagnetic imaging methods, and included application of inverse methods to electromagnetic data from Merapi volcano (Indonesia).
