Summary
👤
Senior🎓
Top SchoolBenjamin Murphy is a Physical Scientist with 12 years of experience studying atmospheric gas and particulate pollution, specializing in the formation, evolution, and removal of organic aerosols. He combines rigorous laboratory box-model experiments, continental-scale air quality modeling (including contributions to the EPA's widely used CMAQ), and high-resolution convective simulations enhanced with custom chemistry to bridge microphysical processes and large-scale air quality impacts. At the EPA he advances both science—focusing on aerosol thermodynamics and kinetics—and code practices to speed and improve model development. His background spans a PhD in Chemical Engineering to postdoctoral work on tropical convection over the Amazon, giving him rare expertise at the intersection of fundamental thermodynamics, atmospheric chemistry, and applied regulatory modeling. Colleagues rely on him for translating complex experimental findings into practical model improvements that inform policy-relevant air quality assessments.
