Dr. Fujita has over 27 years of experience in managing and conducting air quality studies. He is the principal author of the field study plans for the 2000 Central California Ozone Study and 1997 Southern California Ozone Study (SCOS97-NARSTO). His research interests include chemical characterization of emission sources, reconciliation of emission inventory estimates for VOC and PM with ambient measurements, and measurement and characterization of exposure to toxic air contaminants. Dr. Fujita performed source apportionment analysis of fine particles in Colorado’s Northern Front Range, California’s South Coast Air Basin and San Francisco Bay Area, Phoenix, and Bangkok Thailand. Current research includes quantifying the relative contribution of gasoline and diesel exhaust to ambient PM and measuring air toxic exposures from mobile sources. Dr. Fujita also performed volatile organic compound source apportionment studies for the 1987 Southern California Air Quality Study (SCAQS), 1990 San Joaquin Valley Air Quality Study (SJVAQS), 1993 Coastal Oxidant Assessment for Southeast Texas (COAST), 1995 Boston and Los Angeles Study, 1996 Phoenix Ozone Study, NARSTO-Northeast 1995 Summer Ozone Study, 1995/96 Washington Ozone Transport Study, 1996 El Paso/Juarez Ozone Study, and 1998 Central Texas On-Road Hydrocarbon Study. He has conducting similar studies in Houston and Mexicali, Mexico. Dr. Fujita also coordinated laboratory comparisons of VOC measurements during the SCOS97-NARTSO, COAST and NARSTO-Northeast ozone studies
