Earth science PhD candidate Catherine Fontana will pursue cyanobacterial biofilm research at the Lawrence Livermore National Laboratory

Catherine Fontana, a geobiology PhD candidate in the �Ͼ�Ʒ�� Department of Earth Science and the Interdisciplinary Quantitative Biology Program, was recently selected for the for her research on cyanobacterial biofilms.��

The highly competitive program offers PhD candidates in various STEM fields the opportunity to advance their thesis research at one of DOE research facilities alongside a DOE national laboratory scientist. Additionally, awardees are eligible to receive a stipend for general living expenses and inbound and outbound transportation.

“The DOE SCGSR program allows me to study microbial processes using cutting-edge analytical techniques and world-class facilities that are a hallmark of the Department of Energy national laboratories,” Fontana says.

In the Department of Earth Science, Fontana is co-advised by stable isotope geochemist Boswell Wing and microbial physiologist Sebastian Kopf. Her�� seeks to understand the connections between microbial physiology, mineral precipitation and stromatolite (a layered, rock-like formation built by microbial communities) formation using stable isotope geochemistry and experimental evolution.

From October 2026 to April 2027, Fontana SCGSR award will support her study at Lawrence Livermore National Laboratory in California, where she will work closely with Rhona Stuart, who leads the DOE MicroBiospheres Scientific Focus Area. The DOE laboratory offers Fontana the opportunity to leverage a stable isotope technique called NanoSIMS to track variation in stable isotope composition at the micron-scale level.

The project, “Tracking Carbon Flow in Cyanobacteria Biofilms and Their Mineral Byproduct,” explores “how carbon moves through cyanobacterial biofilms and the extent to which this carbon contributes to minerals they make, like carbonate, that eventually turns them into rocks, like stromatolites,” she explains, adding that her work is especially meaningful in the context of developing next-generation biotechnologies in which cyanobacteria and their biofilms may be an innovative foundation for bioeconomy products.

Charting the future of NASA astrobiology

Additionally, after a highly competitive open-call application, Fontana was selected as one of nine early-career scientists to serve on the 49-member NASA-DARES Task Force 2.��Composed of members of the astrobiology community, NASA-DARES, or NASA, will serve as a roadmap for the organization future astrobiology research, which aims to

Since January, NASA-DARES Task Force 2 has been building on—which include comparative planetology to understand habitability and astrobiology in society, among others—identified by Task Force 1 by gathering community input through virtual webinars and public discussions. Task Force 2 is currently synthesizing community perspectives into a document outlining contemporary astrobiological interests, available opportunities and the diverse scientific approaches and disciplines in motion across NASA Science.

As the executive secretary of Focus Area 8, Early Career and Workforce Development, Fontana has worked with her team to solicit and synthesize community input regarding how NASA can best support early-career astrobiologists and develop the field over the next decade.

“As an early career researcher passionate about the future of astrobiology, I am profoundly honored to be part of NASA-DARES,” says Fontana. “As the only early-career member of the ‘Early Career and Workforce Development’ focus area, I feel a strong responsibility to represent early-career voices and perspectives.��This role provides me with a unique opportunity to help shape the chapter findings and contribute to pivotal conversations about the future of astrobiology.”

NASA-DARES is still soliciting feedback: The for NASA-DARES is open this month and close July 2. The final NASA-DARES document will be shared at the American Geophysical Union (AGU) meeting in December.
