The people behind PFI
Geoscientists, engineers, and mathematicians who develop and deliver Permeable Fracture Imaging.
Jeffrey EppinkFounder
Jeff Eppink leads NLES. He is President and Founder of Enegis, LLC, where PFI was developed, and has more than 40 years of experience in oil and gas, carbon storage, geothermal, and energy policy.
Peter Malin, PhDChief Scientist
Peter Malin is Chief Scientist at NLES and leads the science behind PFI. A seismologist with nearly 40 years of experience, he has led seismic work on geothermal projects in Switzerland, Finland, Iceland, Hawaii, and California.
Peter Geiser, PhDStructural Geologist
Peter Geiser is a structural geologist and one of the principal developers of the fracture-imaging approach behind PFI, which he has applied in oil, gas, and geothermal reservoirs for more than 20 years.
James Geiser, PhDMathematician
Jim Geiser is a mathematician who works on the mathematical methods behind PFI processing. He holds a PhD from MIT.
Anastasia Stroujkova, PhDGeophysicist
Anastasia Stroujkova is a geophysicist who works on PFI survey design and analysis. She specializes in seismic network design, borehole instrumentation, and wave-propagation modeling.
Sergio ValenzuelaElectrical Engineer
Sergio Valenzuela is an electrical engineer who handles field engineering for PFI surveys. He has more than 15 years of experience in seismic monitoring, instrumentation, and RF communication.
Austin MathewsGeologist
Austin Mathews is a geologist and GIS specialist who supports PFI projects with geologic mapping, geospatial analysis, and survey planning.
Hector Ontiveros RosalesStaff Researcher
Hector Ontiveros Rosales supports PFI surveys through field acquisition, seismic network deployment, and data quality control. He holds a B.S. in Earth and Climate Science from Duke University.
Frank Horowitz, PhDGeophysicist
Frank Horowitz is a geophysicist who applies mathematical geophysics to geothermal problems. His career includes CSIRO, the University of Western Australia, and Cornell University.
