Dr. Molly Grear is an ocean engineer and marine biologist working in the Coastal Sciences Division at Pacific Northwest National Laboratory. Her work focuses on the environmental impacts of installing new ocean technology, as well as using understanding of biological processes and biomechanics to inspire engineering design. Her recent work has also included coastal development projects, such as modeling and determining the energy needs for kelp cultivation, developing a technical assistance program for communities interested in energy transitions, and understanding community centered design methods for marine energy.  Prior to joining the lab in 2020, Dr. Grear led the National Science Foundation's portfolio in ocean science and technology policy, including advising the White House Subcommittee on Ocean Science and Technology.  

Dr. Grear holds a PhD in Civil and Environmental Engineering from the University of Washington, where she studied the potential injury risk of marine mammals from tidal turbine collision through testing and modeling the structural mechanics of whale skin and blubber.
