About us

“Bridging geophysics and geotechnical engineering for better ground understanding.”

Providing integrated geophysical solutions for geotechnical and engineering challenges—combining scientific rigor, practical experience, and reliable subsurface interpretation.

Our team brings over a decade of intensive field and interpretation experience in GPR, ERT, IP, and MASW, delivering reliable subsurface insights for engineering and resource applications.

The practice is led by a geoscientist with combined experience in academic research, university teaching, and industry consulting, providing a balanced perspective between theory and real-world application.

Professional Journey

The founder began his research career at James Cook University, Australia, developing a strong foundation in geophysics and subsurface analysis. He later continued as a lecturer in geophysics and geostatistics, contributing to applied geoscience education and professional training.

Industry experience with Salva Resources further strengthened practical understanding of geophysical applications in exploration and project environments.

Since 2015, he has been actively engaged in independent consulting, specializing in near-surface geophysical investigation and interpretation for engineering and infrastructure projects.

Expertise and Approach

GeophysicsPro focuses on delivering practical and integrated subsurface solutions, including:

• seismic refraction tomography and MASW Vp,Vs modeling
• electrical resistivity tomography (ERT) and IP
• geophysical data processing and inversion
• integration with borehole and geotechnical data

• ground penetrating radar (GPR)

Processing workflows utilize industry-standard tools such as RES2DINV, Rayfract, Seisimager, Voxler, etc.

The approach emphasizes that geophysical results must be interpreted within geological and geotechnical context to reduce uncertainty and improve engineering reliability. Professional practice aligns with standards recognized by the Society of Exploration Geophysicists.

Vision

To deliver high-quality, internationally competitive geophysical consulting services, supporting engineers and geoscientists in achieving a clearer and more continuous understanding of subsurface conditions.

Collaboration

Services are offered through full investigations, modular consulting, and remote/desktop interpretation, enabling collaboration with clients across different regions and project scales.
