Jochen Marschall
Senior Research Scientist
Molecular Physics Laboratory

Jochen Marschall joined the Molecular Physics Laboratory in 2000. His areas of expertise include thermal protection systems and re-entry heating, experimental measurement of surface, thermal and physical properties, laser-induced fluorescence for species detection and flow characterization, inverse methods and parameter estimation, and modeling of energy and mass transport.

At SRI, Dr. Marschall has participated in or led research in a variety of areas sponsored by NSF, AFOSR, and NASA, including

• Oxidation of Si, SiC, Si₃N₄, HfB₂ and ZrB₂ composites in dissociated oxygen

• Catalytic recombination of CO, O, and N atoms on thermal protection materials

• O-atom degradation of waterproofing agents in low earth orbit

• Impact resistance and microhardness of HfB₂/SiC and ZrB₂/SiC composites

• Gas permeability and thermal conductivity of porous insulations

• Characterization of ceramic heat flux gauges using periodic laser heating

• Collisional energy transfer on vibrationally-excited OH and CO₂

• O-atom interactions with ice surfaces

Dr. Marschall holds a B.S. (1984), an M.S. (1987), and a Ph.D. (1991), in mechanical engineering from the University of California , Santa Barbara . His studies included a two-year National Research Council fellowship at NASA Ames Research Center. Prior to joining SRI, he spent five years in the Thermal Protection Materials Branch at NASA Ames, as a senior research scientist with ELORET. He is a member of the American Institute of Aeronautics and Astronautics, the American Society of Mechanical Engineers, the Materials Research Society, the American Ceramic Society and the American Geophysical Union.

Dr. Marschall is the author of more than 30 publications on surface catalysis, mass and energy transport, thermal property parameter estimation, theoretical large strain elasticity, and materials testing.
