M. Darby Dyar
Darby Dyar's research seeks to understand the distribution of hydrogen and oxygen throughout our solar system, using Mössbauer, reflectance, Raman, synchrotron, and LIBS spectroscopies as well as advanced machine learning technique for data processing and interpretation.She has published more than 260 papers in scientific journals and has been supported by grants from NASA and NSF totaling more than $10 million in the past decade alone. She served as a Participating Scientist on the Mars Science Laboratory mission.
Kate Lepore spends most of her time in the Mineral Spectroscopy Laboratory where she uses laser-induced breakdown spectroscopy (LIBS) to study the elemental composition of geological materials.One of the biggest projects in the lab is the compilation of a nearly 3000-sample LIBS dataset that can be used to improve calibrations for a variety of LIBS systems, including ChemCam on the Mars Science Laboratory rover Curiosity.Kate is also available to assist students with other projects within the department.
Elizabeth Sklute uses a combination of spectroscopy (VNIR, MIR, Raman, and Mössbauer) along with microscopy to investigate hyperthermophilic iron reduction of synthetic, nanophase, iron oxides in order to determine if biosignature could be detected on Mars.These synthetic samples are also used to investigate spectral variation with grain size, shape, and composition in the nanophase size regime.Elizabeth also uses Hapke radiative transfer modelling to calculate optical constants for common planetary materials while investigating the limitations of that technique.
