Kristin Bergmann

Kristin Bergmann grew up in Maryland and the United Kingdom. She attended Carleton College in Northfield, Minnesota where she majored in Geology with an Environmental and Technological Studies Concentration. There she fell in love with field work spending two summers researching the hydrologic changes associated with sagebrush expansion in the southern Sierra Nevada. Prior to graduate school, Kristin worked for the Interstate Commission on the Potomac River Basin and then taught middle school science at the Pennington School in New Jersey.

Kristin pursued her doctorate at Caltech in Pasadena, California with John Grotzinger, John Eiler and Woody Fischer using field and lab work to study the environmental conditions surrounding animal evolution in the Ediacaran, Cambrian and Ordovician. After graduating, she joined the Harvard Society of Fellows as a junior fellow and worked with Andy Knoll on early eukaryotic evolution. She joined the Department of Earth, Atmospheric and Planetary Sciences in the summer of 2015.


Adam Jost

Adam Jost is currently a Research Scientist working in the Bergmann Lab on the geochemistry of Cryogenian-age carbonate rocks from Svalbard. His work to date has focused on understanding ocean acidification and anoxia during the end-Guadalupian and end-Triassic extinctions using carbon, calcium, and uranium isotopes preserved in carbonate rocks from across the globe.

Noah Anderson

Noah Anderson is a graduate student focused on using conodont apatite as a target for clumped-isotope thermometry to better constrain the environmental conditions of Earth during periods of rapid biodiversification. He is also interested in understanding the dynamics of ooid precipitation and abrasion, focusing on the interplay between grain transport and ooid growth.
