Advisory Committee
Dr. David Alumbaugh
Staff Scientist, Lawrence Berkeley National Lab
David Alumbaugh earned his B.S. in Geological Sciences from San Diego State University, followed by M.S. and Ph.D. degrees in electromagnetic (EM) geophysics from the University of California, Berkeley. He began his career at Sandia National Laboratories, co-developing one of the first 3D EM forward-modeling and inversion algorithms for massively parallel computing platforms. He then served as a professor in the Geological Engineering Program at the University of Wisconsin before joining Schlumberger's EMI Technology Center, where he focused on commercializing cross-well EM imaging technology and advancing marine controlled-source electromagnetic (CSEM) methods. Currently, David is a Staff Scientist in the Energy Geosciences Division at Lawrence Berkeley National Laboratory, where his research centers on EM geophysical methodologies for subsurface characterization and monitoring across various applications, including geothermal energy and carbon storage.
Dr. Steven Constable
Professor of Geophysics, Scripps Institution of Oceanography, University of California, San Diego
Steven Constable is a Distinguished Professor of Geophysics at the Cecil H. and Ida M. Green Institute of Geophysics and Planetary Physics, part of the Scripps Institution of Oceanography at the University of California, San Diego. He earned his B.S. with first-class honors in geology from the University of Western Australia in 1979 and completed his Ph.D. in geophysics at the Australian National University in 1983. That same year, he joined Scripps as a postdoctoral scholar and has since held various positions there. Over the past two decades, Constable has led the development and application of advanced electromagnetic sensors for offshore exploration, with his broadband EM instruments deployed on the seafloor over 2,000 times to map subsurface structures using both natural and controlled-source electromagnetic fields.

Lawrence Berkeley National Laboratory affiliate & Geophysical Consultant at Pinecrest Geophysical
Mike Hoversten is a recognized expert in electromagnetic geophysics, with over four decades of experience in advanced methods for subsurface exploration. He has held prominent positions in industry and academia, including roles at Chevron Energy Technology Company, BP, and Lawrence Berkeley National Laboratory, where he currently serves as a research affiliate. His extensive work in controlled-source electromagnetics (CSEM), magnetotellurics, and borehole electromagnetics has significantly contributed to exploration, surveillance, subsurface integrity, environmental remediation, and COâ‚‚ sequestration monitoring.
Dr. Mark Person
Professor of Earth & Environmental Science, New Mexico Tech
Mark Person is a Professor in the Hydrology Program at New Mexico Tech. His research focuses on modeling fluid flow and transport processes in evolving sedimentary basins and continental shelf environments on geologic timescales. He leads the hydrology group for the 2025 NSF-IODP3 501 continental drilling project, focused on offshore brackish water exploration. Previously, Dr. Person held endowed chairs at the University of Minnesota (1993–2001) and Indiana University (2001–2009). He received his B.A. in Geology from Franklin and Marshall College and a Ph.D. from Johns Hopkins University. He is the recipient of the 2021 O.E. Meinzer Award from the Geological Society of America (Hydrogeology Division).
