Dr. Nawaf Nasser is a postdoctoral research in the Department of Earth Science at Carleton University. He received a B.Sc. degree in Geology from Kuwait University (minor: marine science), and M.Sc. and Ph.D. degrees in Earth Sciences from Carleton University. Dr. Nasser specializes in environmental biomonitoring with emphasis on using Arcellinida, a group of shelled benthic lake protists, for tracking modern and past environmental change in the quality of terrestrial aquatic sedimentary systems (i.e., lakes) in response to natural (e.g., climate change) and anthropogenic influences (e.g., land-use changes and industrial activities). His current postdoctoral research is focused on the developing a protocol for using End Member Mixing Analysis (EMMA) of lacustrine sedimentary particle size distributions to reconstruct paleoenvironmental and paleoclimatic conditions in lakes.
