Victoria J. Orphan is a geobiologist at the California Institute of Technology who studies the interactions between marine microorganisms and their environment.[1][2] As of 2020, she is the Chair for the Center of Environmental Microbial Interactions.

Early life and education

[edit]

Victoria Orphan received her B.A. in Aquatic Biology (1994) and Ph.D. in Ecology, Evolution and Marine Biology (2001) from the University of California, Santa Barbara.[3] She served as a National Research Council fellow at the NASA Ames Research Center (2002–2004) before joining the Geobiology faculty at California Institute of Technology.[4]

Career

[edit]

Orphan is the James Irvine Professor of Environmental Science and Geobiology at the California Institute of Technology.[5] She has also been an adjunct scientist at Monterey Bay Aquarium Research Institute (MBARI) since 2009[6] and Senior Scientist of the Center for Dark Energy Biosphere Investigations, a Science and Technology Center funded by the National Science Foundation and headquartered at the University of Southern California.[7] As of 2020, she is the Alan V.C. Davis and Lenabelle Davis Leadership Chair for the Center of Environmental Microbial Interactions.[8][9] In 2023 she was named LGBTQ+ Scientist of the Year by Out to Innovate, a global organization of LGBTQ+ students and professionals in STEM.[10] She is the director of Caltech's Kerckhoff Marine Laboratory as well as the Center for Environmental Microbial Interactions (CEMI).[11]

Research

[edit]

Orphan's research integrates molecular, microscopy, and geochemical techniques to improve understanding of various processes, including those that serve as the primary sink for the greenhouse gas methane in the ocean.[12] She focuses on microbially-mediated anaerobic oxidation of methane (AOM) in deep sea sediment.[13] Specifically, she looks at the relationships between two groups of marine microbes: archaea and bacteria. Orphan uses tools such as nanoSIMS to visualize these organisms at the microscale and track how and when they exchange energy.[14] Through her research, Orphan has helped develop novel stable isotope applications that provide insight into the relationship between microbes and large-scale geochemical processes.[15]

Orphan appeared in the 2018 Netflix documentary The Most Unknown[16] on scientific research directed by Ian Cheney.

Personal life

[edit]

Orphan is in a relationship with fellow scientist Shana K. Goffredi, who teaches biology at Occidental College and also studies deep-sea ecosystems.[17] [18]
