Patrick Gasda is an Adjunct Professor in the Department of Earth and Planetary Sciences at the University of New Mexico, while serving as a Research Scientist at Los Alamos National Laboratory (LANL). His research focuses on Martian geochemistry, astrobiology, and laser-based spectroscopy methods, particularly using data from the NASA Curiosity rover and ChemCam instrument. He investigates boron's role in prebiotic chemistry on Mars and aqueous alteration processes in Gale Crater's sediments.
Gasda's work integrates field observations with laboratory analyses to understand Martian diagenetic histories, climate evolution, and potential habitable environments. His studies emphasize the layered sulfate-bearing units and Marker Band formations in Gale Crater, linking geochemical signatures to past water-rock interactions.
Key areas of research include: (1) trace element geochemistry (e.g., lithium, boron) as tracers of aqueous processes; (2) sedimentary structures (wave ripples, concretions) as paleoenvironmental indicators; and (3) instrument calibration/optimization for planetary rovers. His contributions have advanced understanding of Mars' carbon cycle and potential for prebiotic molecule formation.
Publications emphasize Gale and Jezero Crater geology, with recent work focusing on sulfate unit stratigraphy, manganese enrichment mechanisms, and the implications of rock coatings for late-stage surface alteration. No formal advisees are listed, though his collaborative projects likely involve graduate students at partner institutions.
Gasda's affiliations bridge academia and applied research, combining UNM's Earth sciences training with LANL's planetary exploration expertise. His research has direct relevance to NASA's Mars Sample Return mission priorities and future astrobiology investigations.
