KEITH A. MARUYA – Principal Scientist


EDUCATION:

B.S., Chemical Engineering, University of Southern California, 1983

M.S., Environmental Engineering, University of Southern California, 1986

Ph.D., Environmental Engineering Science, University of California Berkeley, 1995

AREAS OF EXPERTISE:

Dr. Maruya specializes in the analysis, fate and effects of trace contaminants in the aquatic environment. Using mass spectrometry and bioanalytical tools, his work has focused on hydrophobic organic compounds (HOCs) and endocrine disrupting chemicals (EDCs) of anthropogenic and natural origin. Throughout his career, Dr. Maruya has collaborated with the scientific, regulatory, resource management and grassroots environmental communities in characterizing the multi-media fate and effects of HOCs/EDCs. In recent years, Dr. Maruya has led efforts to prioritize contaminants of emerging concern (CECs) for future monitoring in recycled and ambient receiving waters, to develop and adapt in vitro and in vivo screening tools and non-targeted analysis for water quality monitoring and assessment, and to incorporate passive sampling devices (PSDs) for detection of bioavailable contaminants and to better inform management of contamination found in water, sediment and biota. His previous work has addressed bioavailability, biotransformation, remediation, bioaccumulation and trophic transfer of HOCs and CECs in coastal aquatic systems, the use of bivalves and fish as biomonitors, and origins, sources and biological activity of naturally occurring organohalogen compounds.

Prior to joining SCCWRP in 2005, Dr. Maruya was a faculty member at the Skidaway Institute of Oceanography where, in addition to the research described above, he mentored students from the U.S. and abroad, and taught courses in environmental analysis, contaminated sediment geochemistry and coastal oceanography. Currently, Dr. Maruya is directing research to (1) identify and prioritize CECs for water quality monitoring across California, (2) develop bioanalytical and non-targeted methods for monitoring and assessment of CECs in recycled and ambient receiving waters, and (3) develop and field test PSDs to characterize the occurrence, fate and transport of sediment-associated HOCs.
