Keith A. Maruya specializes in the analysis, fate and effects of trace contaminants in coastal aquatic systems. He received his degrees in chemical and environmental engineering from the University of Southern California (B.S. 1983; M.S. 1986) and the University of California, Berkeley (Ph.D. 1995). His research focuses on relevant, cost-effective measurements of toxic contaminants in natural waters and sediments, their occurrence and distribution in coastal watersheds and aquatic food webs, and the analysis of emerging contaminants of concern.
