	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.
	Daniel Keymer (PhD Student) studies Vibrio cholerae he has isolated from California waters. Daniel is the recipient of a Stanford Graduate Fellowship. A phage that infects one of his isolates was isolated from California coastal waters in the Schoolnik lab and is shown at the right. In the photo to the left, Daniel collects data during one of his monthly sampling outings.
	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.)
	Blythe Layton (MS/PhD student) studies oceans and human health. She is particularly interested in enterococci and their ecology. She grew up on a farm.
	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.
	Lesley Silverthorn is an undergraduate at Stanford. She is working with Alyson to examine the influence of temperature on water quality in the surf zone. In this picture, Lesley is holding Beaujolais next to Alyson at the storm drain at the beach adjacent to the Caltech Marine Lab where she worked during the summer of 2005. The picture at the right is Lesley acid washing.
	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.
	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.
	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.
	Alyson Santoro (PhD, 2008). Alyson's 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 will be starting a post doctoral researcher fellowship at Woods Hole Oceanographic Institute in December 2009.
	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.
