Dr. Branwen Williams’s research develops the techniques that we use to generate records of our past ocean and climate variability, and uses these records to understand mechanisms driving environmental changes.  She got her B.Sc. in Marine and Freshwater Biology at the University of Guelph.  She then got her M.Sc. in Biology at GEOTOP with the Université du Québec à Montréal.  She then went to complete at her Ph.D. in Geological Science in the School of Earth Sciences at the Ohio State University.  From there, she did a postdoctoral research fellowship in the Department of Chemical & Physical Sciences at the University of Toronto Mississauga.  She is now an Associate Professor of Environmental Sciences in the W.M. Keck Science Department , a science department that is shared among three colleges of the Claremont Colleges: Claremont McKenna College, Pitzer College, and Scripps College.

Dr. Franck Fu is the 2019 Envirolab Asia postdoctoral fellow at Claremont McKenna College, coming to us with a PhD in Atmospheric Chemistry from the University of Paris Diderot. His research explores aerosol chemistry associated with aquatic and terrestrial landscapes. With Envirolab Asia, he will measure air pollution associated with agriculture in South Korea.

Dr. Kathryn Hargan ( was the EnviroLab Asia postdoctoral fellow at Claremont McKenna College. She is an environmental scientist that uses a wide range of ecological, paleolimnological and biogeochemical techniques to study long-term environmental change in lake and coastal ecosystems in response to anthropogenic stressors. Her current project is exploring nutrient connectivity between aquaculture and coastal ecosystems in southeast Asia. Current position: Assistant Professor at Memorial University in Canada.

Dr. Eleni Anagnostou, postdoctoral fellow with the Williams Lab, was housed at the Department of Marine and Environmental Sciences at Northeastern University.  Her research developed a calibration of the boron isotope-pH proxy in cultured high-latitude coralline algae, and interpreting resulting algal-derived pH records from extremely long-lived wild specimens. She presented the research at the 2017 Goldschmidt conference.   Current position: staff scientist at GEOMAR Helmholtz Centre for Ocean Research Kiel.

Dr. Kelton McMahon, postdoctoral fellow with the Williams Lab, was housed at the Ocean Sciences Department, Institute of Marine Sciences at the University of California – Santa Cruz. His research quantified the amino acid composition of different tissue types of proteinaceous corals.  Current position: Assistant professor at University of Rhode Island Graduate School of Oceanography (

Jessica Ng was a senior thesis student and a post-bachelor researcher in the Williams Lab. Her senior thesis research built the first proxy system model of the oxygen isotope composition of coralline algae. Current position: Ph.D. candidate at Scripps Institute of Oceanography.

Tricia Light was a senior thesis student and a post-bachelor researcher in the Williams Lab.  Tricia’s senior thesis research validated the use of LA-ICP-OES in measuring Mg/Ca in calcite, and identified significant contemporaneous variability in the geochemical composition of coralline algae skeletons.  Current position: Fulbright Scholar in Spain.
