Resume & Bio
Detailed work history and resume
Professional Statement:
Licensed Geoscientist with a proven track record of delivering value by expert interpretation of well and seismic data. Possessing a deep understanding of subsurface investigation, I excel in delivering solutions from concept to execution.
With a strong emphasis on asset acquisition and prospect generation, I've successfully contributed to both onshore and offshore projects. My ability to seamlessly integrate diverse geological datasets and my passion for problem-solving enable me to deliver exceptional results. Additionally, I am actively involved in exploring the potential of carbon capture and storage (CCS) and other emerging energy sectors.
