The Southwest Environmental Health Sciences Center (SWEHSC) announces the following funding opportunity through its Pilot Project Program funded by the National Institute for Environmental Health Sciences (NIEHS). The goal of the SWEHSC is to facilitate and implement innovative research aimed at understanding the mechanisms underlying the modulation of human disease risks due to environmental exposures among populations living in arid environments. Pilot Project funds are awarded to provide short-term support for innovative projects aimed at exploring new areas of environmental health research and acquiring preliminary data necessary to pursue long-term extramural funding and to support the Career Development of new investigators and highly successful senior investigators who wish to redirect their research to include environmental health.
