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.

Contents

Education

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

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

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]

Popularization of science

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

Personal life

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]

<span class="mw-page-title-main">Geomicrobiology</span> Intersection of microbiology and geology

Geomicrobiology is the scientific field at the intersection of geology and microbiology and is a major subfield of geobiology. It concerns the role of microbes on geological and geochemical processes and effects of minerals and metals to microbial growth, activity and survival. Such interactions occur in the geosphere, the atmosphere and the hydrosphere. Geomicrobiology studies microorganisms that are driving the Earth's biogeochemical cycles, mediating mineral precipitation and dissolution, and sorbing and concentrating metals. The applications include for example bioremediation, mining, climate change mitigation and public drinking water supplies.

The American Society for Microbiology (ASM), originally the Society of American Bacteriologists, is a professional organization for scientists who study viruses, bacteria, fungi, algae, and protozoa as well as other aspects of microbiology. It was founded in 1899. The Society publishes a variety of scientific journals, textbooks, and other educational materials related to microbiology and infectious diseases. ASM organizes annual meetings, as well as workshops and professional development opportunities for its members.

<span class="mw-page-title-main">Geobiology</span> Study of interactions between Earth and the biosphere

Geobiology is a field of scientific research that explores the interactions between the physical Earth and the biosphere. It is a relatively young field, and its borders are fluid. There is considerable overlap with the fields of ecology, evolutionary biology, microbiology, paleontology, and particularly soil science and biogeochemistry. Geobiology applies the principles and methods of biology, geology, and soil science to the study of the ancient history of the co-evolution of life and Earth as well as the role of life in the modern world. Geobiologic studies tend to be focused on microorganisms, and on the role that life plays in altering the chemical and physical environment of the pedosphere, which exists at the intersection of the lithosphere, atmosphere, hydrosphere and/or cryosphere. It differs from biogeochemistry in that the focus is on processes and organisms over space and time rather than on global chemical cycles.
