# Mimi R. Koehl

Mimi A. R. Koehl is an American marine biologist, biomechanist, and professor in the Department of Integrative Biology at University of California, Berkeley, and head of the Koehl Lab. She is a MacArthur Fellow from the class of 1990

## Early life and education

Koehl grew up in Silver Spring, Maryland. Her father was a physics professor, from whom she learned math, and her mother was an artist who sold portrait paintings. Koehl has an older brother. As a child, she helped her father in his workshop, where she learned how to use tools.
M. A. R. Koehl enrolled at Gettysburg College as an art major, and switched to biology after taking a biology class as part of her degree requirements. She graduated from Gettysburg College magna cum laude, with a B.A. in biology. After graduation she work at Woods Hole Oceanographic Institution as a lab technician for a summer. She began her studies at Duke University in the fall of 1970, where she studied under Stephen A. Wainwright and graduated with a Ph.D. in zoology. She was a Postdoctoral Fellow (1976-1977) at Friday Harbor Laboratories, University of Washington, where she studied with Richard R. Strathmann, and at University of York, where she studied with John Currey.
She was diagnosed with dyslexia in her mid-forties, and has talked about how it shaped the way she sees the world, and how it influenced her love for fluid mechanics and biology.

## Research

Koehl broadly studies how body structure and physical environment affect an organism's mechanical function in nature, looking across many levels of biological organization. Scientific techniques utilized in Koehl's laboratory range from fluid and solid mechanics to ecological quadrat sampling.
She has studied how marine larvae swim and feed in turbulent flows, and how organisms like kelp, seagrass and coral use currents and waves. Additionally, she has studied the role of hair-bearing appendages in swimming organisms, to both understand their role in propulsion and sensing.
