Research Interests

I am an energy systems analyst with a passion for understanding the interactions between technology, policy and the natural environment. My research has focused on diverse topics including the Energy-Water Nexus, carbon capture and storage, fusion energy, nuclear fuel reprocessing, soldier-portable power and hydrogen. I am the principal investigator for Lawrence Livermore’s Energy Flow Charts (
