About me

I serve as Deputy Division Leader for Science & Technology within the Atmospheric, Earth, and Energy Division at LLNL. In this role, I focus on strategic planning and oversight of the Division's scientific capabilities and research portfolio. I also support the Division Leader in managing approximately 150 scientific and technical staff.

I am also an active research scientist, focusing mainly on greenhouse gas mitigation technologies such as geologic carbon storage and underground hydrogen storage. My work integrates numerical method development, high performance computing, and field monitoring techniques to improve the performance of these complex systems.  Please see the publications link for a representative snapshot of my work.
