Research Opportunities for Undergraduates: Training in Environmental Health Sciences (ROUTES) is focused on increasing the participation of underrepresented minority (URM) undergraduate students in Environmental Health (EH) research. ROUTES will recruit talented URM undergraduates and provide interdisciplinary training, with the long term goal of directing them toward graduate studies and lifelong EH research careers. Specifically, ROUTES will create opportunities for underrepresented students to participate in paid hands-on research experiences, mentoring, and complementary activities. Given that minority populations are disproportionately burdened by exposures to environmental contamination, ROUTES addresses an urgent need to increase awareness and participation of underrepresented groups in EH research.
