Upon completion of her PhD at the University of Washington, she was a postdoctoral scholar at Woods Hole Oceanographic Institution. She has been a member of the Duke faculty since 1992. Professor Lozier was the recipient of an NSF Early Career Award in 1996, was awarded a Bass Chair for Excellence in Research and Teaching in 2000, received a Duke University Award for Excellence in Mentoring in 2007, was named an American Meteorological Society Fellow in 2008, a Distinguished Professor in 2012, a Fellow of the American Geophysical Union in 2014 where she has been elected as president elect. She begins her two-year term as president-elect on Jan. 1, 2019, and then will serve a two-year term as AGU president beginning in 2021. She was named a Fellow of the American Association for the Advancement of Science in 2015. She currently serves as the past-president of The Oceanography Society and is the international lead for the OSNAP (Overturning in the Subpolar North Atlantic Program) observing system.
