Laura E. Rodriguez

Lead

Staff Scientist
Lunar and Planetary Institute

Universities Space Research Association

Dr. Laura Rodriguez is an organic geochemist and data scientist aiming to understand how geologic activity and the physio-chemical properties of oceans drive habitability and facilitates origins of life events on ocean worlds, including early Earth. Specifically, she studies the chemical evolution of CHONPS as it relates to the formation of genetic precursors using laboratory experiments and real-world hydrothermal vent samples. In parallel, she is developing data science methodologies to characterize the organic-geochemistry of such samples using mission-ready techniques. Dr. Rodriguez received her B.S. in Geochemistry (Rice University, 2013) and a dual-title Ph.D. in Geosciences and Astrobiology (Penn State, 2019).

Alta Howells

Co-Lead

NASA Postdoctoral Program Fellow at NASA Ames Research Center

Dr. Howells is a NASA Postdoctoral Program Fellow at NASA Ames. Her primary goal is to aid life detection efforts by developing models that can estimate biological distribution, activity, and biomass production in water-rock hosted ecosystems on Earth and other ocean worlds. To better approximate estimations of biological activity and biomass production elsewhere, she is characterizing growth parameters of Earth methanogens under conditions that reflect other ocean worlds, such as Europa and Enceladus.

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.

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.

IMG_20210809_175553923_PORTRAIT_smaller file size - kirt robinson

Kirtland J Robinson

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.

Natalie Wolfenbarger

Stanford University

Natalie Wolfenbarger received her PhD in geophysics at the University of Texas at Austin in 2022. Her research has evolved from characterizing spacecraft performance as an Aerospace Engineer to examining how data acquired by spacecraft can be used to better understand Earth and other ocean worlds—particularly Jupiter’s ice-covered moon, Europa. Natalie is currently an affiliate member of the Europa Clipper science team supporting verification and validation of the REASON instrument, an ice-penetrating radar designed to peer through Europa’s enigmatic ice shell. Her research aims to understand how we can use radar studies of Earth ice to help interpret future data collected by REASON to investigate Europa’s habitability. Her studies of analog environments for Europa has led her to both the Arctic and Antarctica, where she worked with a team of researchers to conduct aerogeophysical surveys of sites including Devon Ice Cap and Thwaites Glacier.

The Woods Hole Oceanographic Institution is dedicated to advancing knowledge of the ocean and its connection with the Earth system through a sustained commitment to excellence in science, engineering, and education, and to the application of this knowledge to problems facing society. Learn more »
