I am a research geophysicist/entrepreneur, specializing in gravity & electromagnetics (EM) applied to exploration & to studying the foundations of gravity physics. I have developed many scientific instruments for applications in physics, geophysics, biophysics, national defense, & exploration & I am responsible for creating many technical firsts. I set the world’s record in 1999 for the highest resolution force measurement ever made by measuring earth's gravity field to 1 part in a billion. That record stood for 18 years. I have worked extensively in industry, government, & academia. I am an inveterate entrepreneur with extensive, well-honed business leadership, finance, sales, marketing, & mentoring experience. I either started or purchased 9 successful companies in my career, including LaCoste & Romberg, the world’s oldest, & foremost leader in gravity instrumentation; Exploration Instruments LLC, the largest & best known geophysical instrument rental company in North America; EDCON, a world-wide geophysical exploration services company; & Ander Laboratory, an R&D lab in petroleum geophysics that I started with a “Game Changer” grant from Royal Dutch Shell. My customers included Shell Oil, EXXON, Saudi Aramco, Arco, Conoco, Chevron, Baker Hughes, Schlumberger, Rio Tinto, BHP, Newmont Mining Co., & many others. In Government, I worked for Los Alamos National Laboratory (LANL) for 15 years on a wide range of geophysical projects with DOE, DOD, AEC, Army, Navy, Air Force, NASA, NOAA, USGS, USAID, World Bank, etc. I organized & led the International Non-Newtonian Gravity Program to search for a Fifth Force. In Academia, worked at UC-LANL Institute of Geophysics & Planetary Physics (IGPP), at Scripps Institution of Oceanography/UCSD, at UC Berkeley, at UT Dallas, at Texas A&M, & at the U of New Mexico. Studied earth's tectonics, particularly rift structures & basin & range, electrical & thermal states of crust & upper mantle, & propagation of EM fields in earth, from toe-kicking death to core. In 1982, I co-founded award-winning "Summer of Applied Geophysical Experience" School for IGPP. Today, SAGE is the most prestigious geophysical field school in the U.S. I am best known for my geophysical research studies & for developing state-of-the-art gravity sensors. I explored for geothermal energy, oil & gas, minerals, ground water, lost airplanes, buried structures/installations, hidden tunnels, caves, buried utilities, waste, unexploded ordnance, archeological sites, etc. I authored over 100 publications & am a Fellow of the Explorers Club.
