PNNL

Lenaïg Hemery joined Pacific Northwest National Laboratory (PNNL) in 2019 and is an Earth scientist in the Coastal Sciences Division of the Marine and Coastal Research Laboratory at PNNL-Sequim.

As a marine energy specialist (benthic ecologist) at PNNL, she studies the potential effects of marine energy, offshore wind, and marine carbon dioxide removal on the marine environment, especially benthic habitats. Hemery’s research uses an integrative approach that combines fieldwork, laboratory experiments, and numerical modeling to characterize and understand the patterns and processes of marine benthic biodiversity, particularly in relation to human activities at sea. Her interdisciplinary experience in marine biology spans from population genetics to habitat modeling to community ecology, which allows her to bridge biology, ecology, and oceanography topics and investigate research questions related to marine biodiversity macroevolution and conservation, global environmental changes, and sustainable use of marine environments around the world. Hemery is also a member of the research dive team and enjoys deploying and servicing instruments and collecting samples underwater.

Prior to PNNL, Hemery achieved her PhD from Museum national d’Histoire naturelle in France, where she remains an honorary attachée. She then completed a postdoctoral position at Hatfield Marine Science Center in Newport, Oregon.
