BIOGRAPHY

Dr. Laurie Barge is a Research Scientist at the NASA Jet Propulsion Laboratory.
She studies the emergence of life and ways to search for life elsewhere, and is
interested in all worlds where water/rock interactions might have occurred
including early Earth, Mars, and Ocean Worlds (e.g. Europa, Enceladus, Ceres).
Dr. Barge is also the HiRISE Investigation Scientist for NASA's Mars
Reconnaissance Orbiter mission. Dr. Barge co-leads the JPL Origins and
Habitability Laboratory, an astrobiology research team which studies how life
emerges and can be detected on planets. From 2014-2018 she was a member of the
international advisory board of the ELSI Origins Network (EON); and from
2012-2017 she chaired the NASA Astrobiology Institute focus group
"Thermodynamics, Disequilibrium, Evolution" which hosted scientific meetings at
various institutes around the world. Laurie is a steering committee member for
the NASA Astrobiology Program's Network for Ocean Worlds (NOW) and an Action
Group lead for the Network for Life Detection (NFoLD). For her astrobiology
research Dr. Barge has received the NASA Early Career Public Achievement Medal,
the JPL Lew Allen Award, and the Presidential Early Career Award for Scientists
and Engineers. Laurie received her B.S. in Astronomy and Astrophysics from
Villanova University and her Ph.D. in Geological Sciences from the University of
Southern California. After graduate school she was a postdoctoral fellow at
Caltech/JPL and then with the NASA Astrobiology Institute. In her free time she
enjoys running, cycling, and plays the fiddle in a local Irish music group.

COMMUNITY SERVICE

Dr. Barge is Co-PI of the NSF funded project "Pathways in STEM: Cross-Sector
Partnerships, Experiential Learning, and Professional Development", a 5-year
program led by Citrus College which aims to increase the number of diverse
students who are retained and successfully complete STEM degrees at Hispanic
Serving Institute two-year institutions. In the "Pathways in STEM" program
starting in 2020, Citrus College and JPL will join forces with multiple distinct
STEM organizations and institutions to provide experiential learning; mentoring;
education and career advice; development of science communication skills; and
community building for students. The approach for the "Pathways in STEM" program
is built upon lessons learned from a highly successful NSF-funded program that
Dr. Barge was Co-PI of from 2015-2019, "Bridge to the Geosciences (BTTG)" (led
by Citrus College). The overarching goal of the Citrus College BTTG project was
to increase the number of diverse and traditionally underserved community
college students who: (1) were exposed to education and career opportunities in
the geosciences and, through this exposure, (2) opted to transfer to a
baccalaureate degree program in geoscience. The BTTG data showed that the
student participants gained tremendous benefit from exposure to new career
options and being part of a supportive peer community. Dr. Barge is also active
in astrobiology outreach and science communication. She was recently featured on
NASA's "Ask an Astrobiologist" series and NASA's Gravity Assist podcast, and her
research has been featured in various outlets including CBS "Mission
Unstoppable", PBS, NOVA, and Discovery Channel.


RESEARCH INTERESTS

Dr. Barge's main research interests are understanding the origin of life on
early Earth, differentiating abiotic from biological organic chemistry in
geological environments, and exploring hydrothermal vents in the lab and in the
field. She is the Science-PI of the NASA In-Situ Vent Analysis Divebot for
Exobiology Research (InVADER) project, which will send a laser spectroscopy
payload to a hydrothermal vent in the Pacific Ocean. She also leads research
projects relevant to prebiotic chemistry and habitability, including studying
the origin of metabolic reactions in geological settings, and cycling of
phosphorus and nitrogen in redox active mineral systems. Dr. Barge mentors
undergraduate / graduate students and postdocs who are part of her team; see
www.lauriebarge.com for more details about her current research projects.
