	CURRENT STUDENTS AND POST-DOCTORAL SCHOLARS
	Sarah Walters (Post doctoral scholar). Sarah is studying the persistence of nucleic acids in natural waters. In particular, she is working with poliovirus and enterococcus. Her poliovirus plaque assay is shown at the right. She is also running the USDA project to look at pathogens and indicators in coastal streams. She pretty much has her hands in everything.
	Emily Viau (Post doctoral scholar) is studying the health risk of exposure to land based runoff from streams in Hawaii. Her work is funded by the NSF Oceans and Human Health program. She is also assisting in the Tanzania project with the microbiology and pathogen testing of water and hand rinse samples. Emily received her PhD from Yale in 2009 studying pathogens in biosolids.
	Tim Julian (PhD student) is interested in microbial exposure and risk assessment. He is especially interested in rotavirus transmission in day care facilities. In the image to the left, he is sitting on the beach at our Huntington Beach field site conducting some serious experiments.
	Nick de Sieyes (MS/PhD student) is a California Sea Grant trainee. He is studying submarine groundwater discharge along wave-dominated California beaches. In the picture at the left, he is installing well points at our field site at Huntington Beach, Ca. (Nick is on the beach, Keeney Willis is on the ladder.)
	Karen Knee is a doctoral student in geology and environmental sciences. She is co-advised by Adina Paytan and Ali Boehm. She is studying submarine groundwater discharge along the Kona coast of Hawaii and south of the Na Pali coast of Kauai (in Hanalei).
	Kevan Yamahara is a doctoral student in CEE. He is studying enterococci and E. coli in beach sand along the California Coast. Kevan used to be a professional fisherman and is an avid surfer.
	Amy Pickering (center of picture to the left) is a doctoral student in the IPER program, so she has numerous advisors of which Prof Boehm is one. Amy is studying the efficacy of alcohol-based hand sanitizer for reducing bacteria and pathogen concentrations on hands, and improving health in the developing world. Amy is also working on a larger project focused in Dar es Salaam, Tanzania that explores the effect of 'software' interventions on health, water quality, hand hygiene, and attitudes and behaviors towards water.
	Lauren Sassoubre is an engineering degree student. She is studying the distribution of Salmonellae in San Pedro Creek and also the persistence of enterococci in sunlight.
	Todd Russell is a MS student. He is studying denitrification in the sands of Stinson Beach, and also studying the transport of E. coli, enterococci, and coliphage through sands from septic leach fields there.
	Francisco Tamayo is a high school student who works in the lab. He worked with Kevan this past summer studying enterococci persistence in sand. He attends Eastside Prep in East Palo Alto where he is a resident at one of the dormatories. He is an amazing artist and musician! His talents never cease to amaze us!
	FORMER STUDENTS
	Nick Handler (MS with thesis, 2006). He studied the effect of land use on coastal water quality in central and northern California. He is currently working in the lab as a researcher. Nick's sampling sites are shown to the right.
	Daniel Keymer (PhD, 2009) studied the ecology of Vibrio cholerae in California coastal waters. Daniel was the recipient of a Stanford Graduate Fellowship. In the photo to the left, Daniel collects data during one of his monthly sampling outings. Daniel is a post doc at University of Illinois at Urbana-Champaign.
	Alyson Santoro (PhD, 2008) studied the microorganisms responsible for nitrogen cycling in coastal aquifers and how sea surface temperature and other ocean physics controls pollutant and phytoplankton levels in the surf zone. In this picture, she is collecting samples from the surf zone at day break during August of 2005. Alyson was the recipient of an NSF Graduate fellowship. A culture of ammonia oxidizing bacteria and archaea she collected and grew from the subsurface at Huntington Beach is shown to the right. Alyson is a post doctoral researcher at Woods Hole Oceanographic Institute. She is the proud owner of a german shepard.
	Deyi Hou received his MS and ENG degrees. His work focused on risk endured from recreational water contact. He is also studyed the ecology of fecal indicator bacteria and Salmonella spp. in seawater. He was the recipient of the Shaw Fellowship from Stanford University.
	Lynette Jackson (High School Teacher.) Lynette worked on microbial pollution and peristence of enterococci in water, as well as antibiotic resistant bacteria in stream water. She is a science teacher at Leigh High School in San Jose, CA. She worked in the lab in the summers of 2007 and 2008.
	Lilian Lam was a high school senior when she started in the lab. She attends Swarthmore College. She has worked with Daniel Keymer and Blythe Layton. During the summer of 2006, she investigated the variability in Vibrio cholerae across a salinity. During the summer of 2007, she worked with Blythe to study the esp gene in enterococci and what species of enterococci can be found in the environment. She is a whiz at molecular methods and might just be the most productive member of the lab. She is now a graduate student here at Stanford in the Microbiology Department!
