FORMER STUDENTS AND POST DOCS

Todd
Todd Russell (PhD, 2014). He studied the transport of E. coli, enterococci, and coliphage through sands as well as within the surfzone. He led the microbial source tracking project at Cowell Beach, Santa Cruz, CA as part of the State of California Source Identification project.
Simon
Simon Wong (PhD 2014) studied at the intersection of fluid mechanics with water quality science. He studied the effect of internal tides on shoreline water quality at Huntington Beach, CA. He also studied the fate of small plumes in the coastal ocean. Simon currently lives in his home country of Hong Kong. Simon1
Amy
Amy Pickering (PhD, 2011) was a doctoral student in the IPER program where she studied the efficacy of alcohol-based hand sanitizer for reducing bacteria and pathogen concentrations on hands, and improving health in the developing world. Amy is now a post doc at Stanford and works on projects in Kenya, Mali, Bangladesh, and Tanzania.

Nick de Sieyes (PhD 2011) was a California Sea Grant trainee. He studyed 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.) Nick currently works at UC Davis.

Blythe
Blythe Layton (PhD, 2011) studied enterococci in the environment and the relation between climate and health. She is a recipient of the National Science Foundation Graduate Fellowship. She recently began working at Southern California Coastal Water Research Project (SCCWRP) as a post doctoral scholar.
picture of Sarah
Sarah Walters (Post doctoral scholar). Sarah studyed the persistence of nucleic acids in natural waters. In particular, she was working with poliovirus and enterococci. Her poliovirus plaque assay is shown at the right. She also ran the USDA project to look at pathogens and indicators in coastal streams.



Emily Viau (Post doctoral scholar) studied the health risk of exposure to land based runoff from streams in Hawaii. Her work was funded by the NSF Oceans and Human Health program. She also assisted 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, 2010). His thesis is entitled Fomites in Infectious Disease Transmission: A modeling, laboratory, and field study on microbial transfer between skin and surfaces. He was a post doc in Kellog Schwab's group at Johns Hopkins School of Public Health in Baltimore and is now a professor at EAWAG in Zurich, Switzerland.

Karen
Karen Knee (PhD, 2010) Karen was a doctoral student in geology and environmental sciences. She was co-advised by Adina Paytan and Ali Boehm. She studied submarine groundwater discharge along the Kona coast of Hawaii and the North shore of Kauai (in Hanalei). She was a Fulbright Scholar working in Ecuador and is now a professor at American University in Washington DC.

picture of Maggie
Maggie Montgomery (Post doctoral scholar 2009-2010) worked on the Tanzania project to understand how providing personalized information on water quality and hand contamination influences people's behaviors and attitudes about water, as well as their health and stored water quality, and hand contamination. She is currently working on international water and health issues at the WHO in Geneva.


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 was a post doc at University of Illinois at Urbana-Champaign as well as University of Georgia. He is now a professor at University of Wisconsin Stevens Point.

picture of Alyson
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 a professor at Horn Point Marine Lab in Maryland in 2011. She is the proud owner of a german shepard.


Nick in the
							  field
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. Nick now lives in Uganda where he works for One Acre Fund.




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.

Francisco
Francisco Tamayo was a high school student who worked in the lab. He worked with Kevan Yamahara studying enterococci persistence in sand. He attended Eastside Prep in East Palo Alto where he was a resident at one of the dormatories. He is an amazing artist and musician! His talents never cease to amaze us! He is now an undergraduate student at Yale. Go Francisco!


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!
