Ivria Doloboff

Research background in developing instrumentation for planetary exploration and advancing state of knowledge in detection and definition of biosignatures. Ivria's works focuses on testing and developing methods for detection of life and biosignatures on other planets. This includes developing structured methodologies and techniques for using deep UV laser-based spectroscopic instruments to perform fine-scale detection of minerals and organic molecules. Laboratory research includes simulating far-from-equilibrium chemical/geochemical systems relevant to the emergence of life on wet rocky worlds. These efforts involve work in various analytical techniques, including characterization of geochemistry and geomorphology of terrestrial, Lunar, comet, and Mars simulants using Environmental Scanning Electron microscopy (ESEM) and Energy Dispersive X-Ray spectroscopy (EDS).
