Deniz Ertaş, Ph.D. is a theoretical physicist with deep expertise spanning geophysics, materials science, granular and porous media, drilling mechanics, electrochemistry, and geothermal energy. Born and raised in İzmir, Türkiye, he moved to the U.S. in 1990 to pursue a Ph.D. in Theoretical Condensed Matter Physics at the Massachusetts Institute of Technology (MIT). Since then, he has spent over 25 years leading research and innovation in the energy sector, with a particular focus on technologies related to the exploration and production of oil and natural gas.

Deniz is the author of more than 50 peer-reviewed publications and is the inventor of two dozen patents. His commitment to philanthropy began with a memorial scholarship fund for his high school principal, and has since grown into a long-standing dedication to educational access in Türkiye. A BTF volunteer since 2018, Deniz has been instrumental in raising scholarship funds for students from his alma maters Bornova Anadolu Lisesi and İzmir Fen Lisesi.

As Secretary of BTF’s Board of Directors since July 2025, he continues to channel his passion for science and equity into meaningful impact. Most recently, he helped establish BAL America, a growing alumni network that supports education and opportunity for the next generation.
