Val received her BS in Earth Sciences (paleobiology & geology) from UC Santa Barbara in 2021. As an RA at Johns Hopkins University, she became interested in using lab and field techniques to answer questions related to perturbations in...

She/Her/Hers My name is Daianne, and I am originally from Brazil, where I obtained a BSc in Geology and an MSc in Geochemistry. During my studies at Texas A&M University, I transitioned from U-Pb zircon geochronology to organic geochemistry. Isotopes are...

I am interested in global biogeochemical cycles, seawater chemistry, and paleoclimatology on various geologic timescales. Stable isotope geochemistry and numerical modeling are the primary techniques for my research. My current project focus on the high...

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...

he/him/his or they/them/theirsBeck is a rising junior at Harvard College pursuing a joint concentration in Chemistry and EPS. He is starting as a research assistant in the Johnston Group in summer 2020 with plans to explore multiple topics within the...

Chloé-Rose is a senior at Harvard College concentrating in Organismic and Evolutionary Biology with a secondary field in Earth and Planetary Sciences, focusing on marine sciences. She joined the Johnston group in the summer of 2020 to work on a...

Ella is coming to Harvard from the UK, where she completed a BA degree in Natural Sciences and MSc degree in Earth Science at the University of Cambridge. Her Master’s research at Cambridge and Caltech focussed on the sulfur isotope composition of organic...

She/Her/Hers Haley received a BA in Geology from Carleton College in 2017. Haley's research uses stable isotope geochemistry to constrain marine geochemical conditions throughout geologic time (thus far from the Archean to the Neogene). She is currently...

Katherine received her BA in Environmental Chemistry from Columbia University in 2014. Since then, she has worked at the US Geological Survey on Quaternary paleoceanogprahic and hydroclimate reconstruction in the Arctic. At Harvard, she will...

I combine approaches from the bio- and geo-sciences to address big-picture questions about the history of life on Earth and the potential for life elsewhere. This research is motivated by a desire to understand how life and the planet have changed...
