Lenaïg Hemery is an Earth scientist in the Coastal Sciences Division at the Marine and Coastal Research Laboratory at Pacific Northwest National Laboratory (PNNL) Sequim. She earned her bachelor’s degree in Organisms and Population Biology from the University of Western Brittany (France); her master’s degree in Systematics and Evolution from the University of Pierre and Marie Curie (France); and her PhD in Ecology and Evolution from the National Museum of Natural History of Paris (France), where she remains an Honorary Attachée. She then completed a postdoctoral position at Hatfield Marine Science Center, in Newport, Oregon. Lenaïg is now a marine energy specialist (benthic ecologist) at PNNL, where she studies the potential effects of marine energy, offshore wind, and marine carbon dioxide removal on the marine environment, especially benthic habitats.
Lenaïg’s research uses an integrative approach that combines fieldwork, lab 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 uses of marine environments around the world.
Lenaïg is also a member of the research dive team and enjoys deploying and servicing instruments and collecting samples underwater.
