Meet the team

Founder and 

Chief Technical Officer

Dr. Malin has nearly 40 years of experience in crustal seismology and geophysical research – in both academic and industry settings. He holds a Bachelor's and a Master's degree in Geophysics from Stanford University, as well as a PhD from Princeton University. Known for his work in fault-zone and energy reservoir seismology, borehole seismology, instrument design and installation, seismic monitoring, and fracture research, he has worked extensively on several continental plate-boundary transform faults and non-conventional energy reservoirs. He has been responsible for the design, installation, and monitoring of non-conventional energy reservoirs around the globe. In Basel, Switzerland, he and his team installed borehole microearthquake sensors to monitor a geothermal energy project’s seismic impacts. Based on the lessons learned at Basel, Malin’s team successfully guided a similar EGS project in Espoo, Finland, to completion without exceeding regulation seismicity. Number of refereed publications in major journals: 112, extended meeting abstracts: 54, books: 1 in progress.

Chief Engineer

Sergio G. Valenzuela is a seasoned Electrical Engineer specializing in RF communication and seismic monitoring. He earned his M.Sc. in Electrical Engineering from North Carolina State University and a B.Sc. in Electrical Engineering from The University of Arizona. With a solid background in both in-house and remote-site technical project management, Sergio has successfully led and implemented strategies for field operations, focusing on seismic monitoring stations, telemetry systems, and data integrity. His professional experience includes working with seismic networks, from station installation to data processing, and developing automation scripts to convert seismic data into various formats. Sergio has also designed and built RF systems, including radio transmitters, and has hands-on experience with advanced engineering tools.

Operations and Technology Staff 

Hector Ontiveros Rosales is an earth science and computer science graduate from Duke University, currently working with Seisfocus, LLC on applied geothermal and subsurface characterization projects. At Seisfocus, he supports field-based geophysical operations and well characterization, including drilling support, lithologic logging, near-surface geophysical surveys, and deployment of downhole monitoring systems for Aquifer Thermal Energy Storage (ATES) and related subsurface studies. His work bridges field acquisition and data interpretation, contributing to integrated models of subsurface structure and flow. His background includes research and field experience with Enegis, LLC, where he contributed to ambient seismic imaging workflows, seismic network deployment, and data quality control for geothermal exploration. Earlier, his undergraduate research at Duke focused on building data pipelines for environmental systems and participating in NSF-supported freshwater and subsurface projects.
