The people behind ReMi®.

Bill Honjas

Bill Honjas is Co-Founder and Chief Executive Officer of Terēan®, bringing decades of leadership at the intersection of geophysics, seismic risk, and advanced imaging technologies. Prior to Terēan, Bill founded and served as President of Optim Earth (acquired by Orix Capital Partners, NYSE: IX), where he led the development of pioneering software platforms, SeisOpt® and ReMi®, that have since become global standards in geotechnical analysis. Under his leadership, Optim delivered breakthrough technologies that advanced public safety, transformed large-scale seismic risk assessment, and significantly accelerated geothermal energy exploration.

Bill’s career in seismology began through a long-standing collaboration with the Nevada Seismological Laboratory, ultimately spanning public-sector, scientific, and international work. He served as Managing Scientist for on-site operations under the NRDC Nuclear Weapons Test Ban Verification Project, working in secure test and research locations across the United States and the former Soviet Union. He later became Director of the Global Seismic Network at the Scripps Institution of Oceanography’s Institute for Geophysics and Planetary Physics, where he led global expansion of the network into the South Atlantic and Middle East. Bill also served as Director of Geophysics and Senior Geophysicist at William Lettis & Associates, where he drove the firm’s growth into international markets.

Bill currently serves on the College of Science Advisory Board and Strategic Planning Committee at the University of Nevada, Reno, where he was honored as Alumnus of the Year.

Alison Starr

Alison Starr is Co-Owner and Chief Operating Officer of Terēan®, where she leads company operations and helps guide the growth and application of its seismic imaging technologies.

Alison began her career in geophysics at the University of Nevada, Reno, working on seismic acquisition and processing for projects ranging from geothermal exploration to basin-scale fault mapping. She later earned an MS in Geophysics from the University of Utah, with an emphasis in Structural Engineering, before joining Chevron, where she spent five years working on seismic imaging and modeling for domestic and international exploration projects.

Alison returned to Reno and joined Terēan in 2023. Today, she combines her technical background with operational leadership to advance ReMi® technology and expand its practical applications across engineering, mining, energy, and geologic investigations.

Prof. John N. Louie

John N. Louie is Co-Founder and Chief Technology Officer of Terēan® and Professor of Geophysics, Emeritus at the University of Nevada, Reno. He has more than 40 years of teaching and research experience in geophysics and seismology, with a focus on seismic imaging, earthquake hazards, and subsurface characterization.

Prof. Louie pioneered the Refraction Microtremor method, which became the foundation for ReMi® technology. His research has also advanced seismic imaging of faults, geothermal exploration, 3D earthquake ground-motion modeling, and community resilience to natural hazards.

In 2023, Prof. Louie co-founded Terēan, where his decades of research continue to inform the advancement of ReMi® technology and its expanding applications across engineering, mining, energy, and geologic investigations.

Dusty Barnes

After receiving his BS in Computer Science Engineering from the University of Nevada, Reno (UNR) in 2018, Dusty Barnes continued at UNR for his MS, collaborating with Prof. Louie and Bill Honjas to improve plot generation methods and apply machine learning to geophysics.

After graduate school, Dusty worked in industry on a variety of projects including developing bespoke AI customer workflows, advancing infrastructure for training and deploying models, as well as integrating hardware (sensors, cameras, etc.) with software systems. Dusty is also a veteran of the NV Army National Guard, serving from 2016–2024.

In 2023, Dusty co-founded Terēan, leveraging his technical expertise to bring geophysical innovations to the community.

Aasha Pancha, PhD

Aasha Pancha holds BS and MS degrees in Geophysics from Victoria University of Wellington, New Zealand, and a PhD in Geophysics from the University of Nevada, Reno, Seismological Laboratory. Her PhD work contributed to improving seismic hazard models for the U.S.A. National Seismic Hazard Map and her career has spanned academic research to the engineering industry.

Aasha’s research has been instrumental in the development of the refraction microtremor method for engineering and seismic applications — from imaging very shallow subsurface material structures, to characterizing basin geometries. Aasha worked for Optim SDS Inc from 2007 to 2014, building a strong foundation in ReMi™ software and played a significant role in the hazard mapping of Las Vegas using refraction microtremor technology.

Her focus is the characterization of near-surface materials for earthquake shaking assessment and engineering application, as well as the imaging of buried faults under urban areas. This work contributes toward the reduction of earthquake losses in high-risk urban areas and demonstrates how using geophysical methods minimizes geotechnical risks by enhancing the ability to obtain a more thorough geological understanding of subsurface conditions.

Andrew Rosenberg-Main

Andrew Rosenberg-Main earned his BS in Geophysics from the University of Nevada, Reno. During his undergraduate studies, Andrew conducted fieldwork and data acquisition for geothermal projects in Central Nevada with the Nevada Seismological Lab and performed electrical and EM surveys for geophysical exploration with Zonge International.

After graduating, Andrew worked for Optim, building a strong foundation in ReMi® and seismic refraction acquisition and processing. He currently works for the Nevada Seismological Lab acquiring seismic data, and he joined Terēan in Summer 2024.

Dylan Scofield

Dylan Scofield obtained his BS in Engineering with a focus on Sustainable Design from James Madison University, where engineers are cultivated to drive positive change through innovation to benefit both industry and society.

With a passion for sales and a proven track record of collaborating with inventors to shepherd patented products to market, Dylan brings a unique blend of technical knowledge and business acumen to his role. He joined Terēan in 2024 with the goal of expanding the company’s global reach and advancing its mission to save customers time and money while making the world a safer place.
