The Northern California Center for Occupational and Environmental Health (COEH) is a permanent addition to the School of Public Health and is based in the EHS Division. It provides leadership and an institutional infrastructure to supplement the EHS Division in coordinating many diverse environmental health activities. Established in 1980 by the University of California in response to California legislative mandate, it coordinates environmental health activities of 60 faculty on three UC Campuses. EHS faculty member Robert C. Spear was the founding director and continues to direct the Berkeley components of this interdisciplinary center. Newly appointed SPH faculty member John Balmes, whose primary appointment is with the School of Medicine at UCSF, is the director and facilitates collaboration with UCSF faculty. With funding for only 1.5 faculty FTE at Berkeley, COEH resources have been leveraged so that, currently, fifteen Berkeley faculty are affiliated with COEH (predominantly from the School of Public Health, but also in the Department of Psychology and the College of Engineering). COEH links the EHS program to labor, community, professional groups, and to clinically oriented academic programs at UC Davis and UCSF.
