Hope  A Michelsen Technical Staff Member Combustion and Atmospheric Chemistry

Hope Michelsen, Technical Staff Member, Combustion and Atmospheric Chemistry


Hope Michelsen has been a technical staff member in the Combustion Research Facility at since 1999.  Her background is in physical, atmospheric, and combustion chemistry, and her current research program focuses on understanding the formation and evolution of combustion-generated particles in combustion systems and the atmosphere and developing laser-based techniques for detecting these particles. She is also studying the impact of short-lived climate forcers, such as black carbon and methane, on regional Arctic and global climate. Her research experience includes gas-surface scattering experiments, atmospheric modeling, soot-formation studies, combustion-diagnostics development, atmospheric black-carbon measurements, climate feedback mechanisms, and greenhouse-gas source attribution.  She received an A.B. in Chemistry from Dartmouth College and a Ph.D. in Chemistry with a minor in Physics from Stanford University.  She completed an NSF postdoctoral fellowship at Harvard University and worked at Atmospheric and Environmental Research, Inc. before joining the technical staff at Sandia.
