Professor and Chair, Department of Ecology, Evolution, and Environmental Biology
Ph.D., Zoology, University of California, Berkley, 1989
Naeem studies the ecological and environmental consequences of biodiversity loss and is interested in how changes in the distribution and abundance of plants, animals, and microbes affect ecosystem functioning and services.
This work has demonstrated how the loss of species from ecosystems affect their ability to resist invasion by other species, affect production and nutrient cycling, and affect the reliability and stability of ecosystems. His theoretical work examines how mathematical engineering reliability models can be used to understand the effects of biodiversity loss, global change, management, and environmental degradation on ecosystem reliability.
His current fieldwork is concerned with how extrinsic factors, such as soil fertility and disturbance interact with plant biodiversity to regulate the spread of invasive plant species in old fields at the Cedar Creek Long Term Ecological Research in Minnesota; he plans to expand this work to Black Rock Forest here in New York.
Naeem also coordinates a group effort to predict the local, regional, and global impacts of biodiversity loss across a wide variety of ecosystems, and he is actively involved in bringing the science of biodiversity and ecosystem functioning to conservation, restoration, and policy development.

Associate Director and Director of Research, the Earth Institute Vinton Professor of Earth and Environmental Engineering in the Faculty of Engineering and Applied Science
Professor, Department of Earth and Environmental Sciences
B.S. /M.S., Heidelberg, 1981; Ph.D., 1985.
Schlosser's research focuses on water systems, primarily in oceans and groundwater. His work reflects his concern about problems caused by human impact and needs for solutions based on thorough scientific understanding of natural systems. His water movement studies utilize natural and anthropogenic trace substances such as radiocarbon, oxygen-18, radioactive hydrogen and its decay product He-3, as well as measurement of noble gases in groundwater.
His groundwater flow studies concern shallow and deep aquifers, especially as they relate to environmental risk/impact studies. Results permit reconstruction of continental paleotemperatures records and flow studies. Schlosser's ocean research concerns water circulation in the ocean surface, movement into the deep ocean, and circulation patterns within the deep ocean. This work includes linkages to the climate variability and age dating of the water masses.
Current research also is directed toward an exploration of mixing and gas exchange in river and estuary environments, particularly utilizing SF-6 and He-3 studies. Schlosser's publications include "SF-6 and He-3 tracer release experiment: A new method of determining longitudinal dispersion coefficients in large rivers," Environment, Science and Technology (1996, with J. Clark, M. Stute and H.J. Simpson); "Paleotemperatures in the southwestern United States derived from noble gases in ground water," Science (1992, with M. Stute, J. Clark and W.S. Broecker); and "Reduction of deepwater formation in the Greenland Sea during the 1980s: evidence from tracer data," Science (1991, with G. Boenisch, M. Rhein and R. Bayer).
