Ellen is a geomicrobiologist with a Bachelor's in Microbiology & Immunology from the University of Texas at San Antonio. She is interested in mineral composition and its impacts on lipid preservation in extreme environments, more specifically, the influence of iron-bearing minerals on lipid deposition in the rock record. She works with Shawn McGlynn, Mary Beth Wilhelm (NASA Ames), and Scott Perl (UCLA-EPSS) to characterize the lipid biomarker profiles and preservation mechanisms of two Mars analog sites: the Okuoku Hachikurou (OHK) hot spring in Akita prefecture, Japan. She is utilizing the OHK Fe-rich hot spring and hypersaline springs as temporal proxies for the evolution of fossilized lipids to develop an analytical framework for comparing preservation potential across varying geochemical datasets. The primary goal of her work is to inform our interpretation of lipid preservation throughout Mars' transitory climate history.

Jose holds a B.A. in Biology and is starting his future doctorate in Microbiology. Jose's main goal is to investigate and understand specific extreme microorganisms ("extremophiles") that inhabit planetary analogue environments such as saline lakes, hot springs, and hydrothermal vents. Jose uses these studies to bridge gaps between observational biosignatures and microbiological exchanges in the environment within the many biomes the world possesses. Recently, Jose has become interested in the metabolisms of the microorganisms that are residing in these extreme environments.
