He has expertise in the advancement of in situ methods of chemical analysis, particularly: high-resolution magnetic sector, Orbitrap, time-of-flight, and linear ion trap mass spectrometry; laser ablation and desorption sample processing; and, electron probe microanalysis (EPMA) of terrestrial and extraterrestrial materials (including planetary analog samples). His scientific research focuses on establishing comprehensive models of the chemical compositions of planetary interiors, and characterizing the biosignature preservation potential of different mineral phases. He has also served as a member of the SAM Science Team and the Product Development Lead (PDL) for the mass spectrometer subsystem of the MOMA instrument on the ExoMars rover.
