Career path

I have worked toward developing materials for climate change mitigation since 2010.  Early work was focused on using advances in manufacturing to realize improved mass transport in carbon capture and conversion materials.  Recently, my research has broadened in scope and includes systems level analysis to identify opportunities for carbon removal, as well as developing scientific capabilities to de-risk scaleup for promising climate change mitigation technologies. I currently enjoy a fulfilling mix of management/mentorship, program development and scientific /individual contributor roles at LLNL.



I am the lead author of Getting to Neutral: Options for Negative Carbon Emissions in California, the first comprehensive analysis of carbon dioxide removal pathways, impacts and opportunities in California. The report won the DOE Secretary’s Achievement Award in 2021.
