Dr. Raymond Najjar is a Professor of Oceanography with the Departments of Meteorology and Geosciences at The Pennsylvania State University. Dr. Najjar was a member of the multi-disciplinary research team that recently undertook a Pennsylvania climate impacts assessment under the auspices of the state, and earlier served in a similar capacity with the Mid-Atlantic Regional Assessment (MARA) and the Consortium for Atlantic Regional Assessment (CARA)—EPA-funded projects that provided climate information to stakeholders in the Mid- and Upper-Atlantic Regions of the United States. Dr. Najjar’s current climate assessment activity is with the Partnership for the Delaware Estuary. He served on the National Academy of Sciences Climate Research Committee and currently serves as one of two Pennsylvania-appointed members of the Science and Technical Advisory Committee of the Chesapeake Bay Program. Dr. Najjar’s research ranges from the role of the ocean in global biogeochemical cycles and climate to the physical and biogeochemical dynamics of Mid-Atlantic estuaries and their watersheds; the effect of anthropogenic activity on these systems is a theme that runs through this work. He has authored or coauthored over 40 journal articles.
