Julien Foriel
julien_foriel@fas.harvard.eduResearch Scientist
He/Him/His I am an isotope geochemist, and like all isotope geochemists, I like to build and tinker with instruments, develop new analytical methods and new isotopic tools to understand elemental cycles on Earth. I am particularly interested in the...
Maddie Goldberg
madisongoldberg@college.harvard.eduUndergraduate Research Assistant
I’m a junior studying Earth and Planetary Sciences with a secondary in Educational Studies. I joined the Johnston group in the spring of 2019 as an undergraduate research assistant and am now beginning my senior thesis with the lab, conducting isotope...
Maya Gomes
mayagomes@fas.harvard.eduFormer Post-doctoral Fellow
Now on faculty at Johns Hopkins UniversityMaya is interested in how the cycling of elements through the ocean and atmosphere regulates climate and habitability. Specifically, she focuses on how the sulfur cycle interacts with the carbon, oxygen, and...
Ana Gonzalez Valdes
gonzalezvaldes@g.harvard.edu5th Year Ph.D Student
Ana Gonzalez Valdes received her B.A. in Earth Sciences from Columbia University in 2016. At Columbia and Caltech she worked to understand how microbes in unique environments cycle nutrients like phosphorus and sulfur. At Harvard Ana will be spanning the...

Karina was an undergraduate joint concentrator in Earth and Planetary Science and Environmental Engineering who has been working with the Johnston Group since her sophomore year. Her interests in biogeochemistry carries across sulfur, oxygen, and nitrogen...
Jordan Hemingway
jordon.hemingway@erdw.ethz.chAssistant Professor/ETH Zurich
He/Him/His I'm interested in connections between the geologic and biospheric carbon cycles. Specifically, my work aims to understand how processes occurring in river basins transfer carbon between these two cycles in order to regulate atmospheric CO2...
Eve-Lyn Hinckley
Eve.Hinckley@Colorado.eduVisiting Professor
Eve-Lyn Hinckley’s research focuses on studying the elements that underlie all life on Earth, with an emphasis on how they are changed by human activities and how those changes feed back to affect human welfare. Dr. Hinckley earned her Ph.D. in Geological...
