Research interests

Simon is interested in development and implementation of materials and technologies for carbon dioxide removal, the interface between carbon capture technologies with carbon conversion to develop a circular carbon economy, and systems analysis for carbon removal and energy technologies. He leads DOE-funded projects spanning topics from fundamental investigations of direct air capture materials degradation mechanisms to development of hybrid reactive capture processes that integrate carbon capture and conversion. He leads the Direct Air Capture pillar of the LLNL Carbon Initiative.

Current position(s)

• Associate Group Leader, Materials for Energy and Climate Security
• Direct Air Capture Lead, LLNL’s Engineering the Carbon Economy Initiative

Subject matter expertise

• Direct air capture of carbon dioxide
• Carbon capture and catalytic conversion
• Functional porous materials and polymers
