Miquela Ingalls is an Assistant Professor of Geosciences and faculty in the Biogeochemistry and Astrobiology programs at Penn State. Miquela studies modern and ancient carbonate environments, with a particular interest in how microbes interact with carbonate minerals in lakes. Miquela's group uses elemental, stable, and clumped isotope techniques to reconstruct past environments, biology, and aqueous chemistry.

Rachel is an Assistant Professor of Geosciences and an associate of the Penn State Earth and Environmental Systems Institute.  Her research uses field data and numerical models to understand groundwater flow and transport processes in complex hydrologic systems. She aims to apply her work to understand water resource availability and improve predictions of environmental hazards, such as flooding and erosion. 

Brian Kelley is an Assistant Professor of Geosciences at Penn State who investigates the relationship between environmental change, biological evolution, and carbonate sedimentation. Brian also worked as an industry geoscientist, where he studied world-class carbonate reservoirs in the Middle East, Europe, South America, and North America.  

Kim Lau, Assistant Professor in Geosciences, is a sedimentary geochemist. She combines inorganic geochemical proxies, fieldwork, and modeling to understand paleoenvironmental change during critical intervals in the past as windows into the Earth system, as well as to improve our interpretations of the sedimentary geochemical record.

Kat Dawson is the Director of the Biogeochemistry Section at the Patrick Center for Environmental Research at the Academy of Natural Sciences. She utilizes tools from geochemistry and microbiology to explore questions about microbial influences on biogeochemical cycling and their chemical and isotopic signatures in the environment. 

Max is an Assistant Professor of Geosciences at Penn State. He uses new geochemical tools to tackle unresolved questions regarding surface and near-surface processes on Earth, combining hard isotopic analyses and simple models to understand how these processes work today, and how they may have operated in the past.
