Elizabeth Spiers

Lead

Georgia Institute of Technology

Elizabeth Spiers is a PhD Candidate at Georgia Tech studying thermal and geochemical coupling and fluxes within the interior of Europa throughout its evolution. By understanding how thermal and chemical processes work together as a system within the interior, the potential for life and habitability at Europa can be better quantified. She has additional experience in mission design work having been a part of Georgia Tech’s (Vertical Entry Robot for Navigating Europa) VERNE concept vehicle team and the Principal Investigator for a JPL Planetary Science Summer School feasibility study for a New Frontiers mission to Enceladus, called Tiger.

Kirtland J Robinson

Co-Lead

Woods Hole Oceanographic Institution

I am developing a framework whereby organic reaction species can be used as geochemical tracers for subsurface aqueous environments. Organic reaction species can be mobilized from environments that are difficult to directly access and brought to more accessible sampling locations, bearing signatures of their source conditions. Constraining subsurface aqueous conditions within icy ocean worlds will improve assessments of whether these environments can support life.

I conduct my work using hydrothermal experiments, thermodynamic and kinetic reaction modeling, as well as collecting and analyzing environmental samples to ground truth those models.

My other research interests include prebiotic chemistry and biosignature detection.

Lily Clough Branstetter

The University of Tulsa

I am currently pursuing my Masters at the University of Tulsa in Geosciences with a focus on Computer Science. I recently completed an internship with NASA Goddard Space Flight Center, with my research focusing on machine learning for ocean world laboratory analog seawater volatiles. We hope to predict subsurface or oceanic conditions given plume or exosphere mass spectrometry data. I am also researching the phylogenetics of astrobiologically significant extremophiles and their biogeochemistry. By studying this, I hope to make inferences about the possible nature and environments of early life on Earth and that of postulated astrobiological life.

Patrick C Gray

Duke University Marine Lab

I'm currently a PhD candidate with Dave Johnston in the Marine Robotics and Remote Sensing Group at the Duke University Marine Laboratory and a Future Investigator in NASA Earth and Space Science and Technology (FINESST).

My doctoral research uses satellites, drones, and in-situ optical techniques to understand the interplay of physics and ecology in the ocean. Combining remote sensing, data science, and biological oceanography I lean on machine learning for parsing large amounts remote and in-situ data. I'm very interested in tools and research that’ll be relevant for both Earth science and exploring other oceans within our solar system.

Rachel Harris

Harvard University

I am a postdoctoral fellow in the Girguis Deep Sea Microbiology Lab. My research explores the biogeochemistry and ecophysiology of SLiMEs – Subsurface Lithoautotrophic Microbial Ecosystems – as a proxy for investigating the astrobiological potential of other worlds. My work often combines multiple tools, including tracer experiments, imaging, 'omics, and metabolic modeling, to explore the habitable limits of life and the metabolic strategies it employs to survive the biotic fringe. When I'm not working with SLiMEs, methanogenic archaea (methane-producing microbes) are my favorite model organisms for astrobiology-related research.

Kristin Johnson-Finn

Earth-Life Science Institute; Tokyo Institute of Technology

I am currently a research scientist at the Earth-Life Science Institute in Tokyo, Japan. My research focuses on the interactions of organic compounds with different minerals to form additional reaction pathways, mostly at hydrothermal conditions. I pursue these questions with an expanding array of experimental (hydrothermal, electrochemical, VSM, etc.) and thermodynamic techniques. I am interested in abiotic and potentially prebiotic reactions available through organic / mineral interactions in the icy moon environments of Europa and Enceladus. I want to unravel the abiotic signals from the biotic signals in these environments in the search for life on ocean worlds.
