Isotopes carry clues to the physical and chemical processes happening all around us. I am a Research Scientist I at the Institute of Arctic and Alpine Research (INSTAAR), University of Colorado Boulder, working with Dr. Bradley Markle. I study how the isotopes of water and carbon move through polar environments and what they reveal about our changing planet. My current research combines machine learning, atmospheric back trajectories, and water isotope distillation to better understand Arctic hydroclimate.

I completed my Ph.D. in Earth Science at CU Boulder in August 2026, advised by Dr. Tyler Jones and Dr. Irina Overeem. My dissertation explored the biogeochemical indicators of methane escape from abrupt-thaw permafrost lakes.

You might find me in the lab, tuning instruments and processing samples; at my computer, building and testing numerical models; or deep in the field, flying drones and collecting data to better understand Earth’s climate system. I work in glacial and permafrost landscapes where Arctic amplification is driving rapid environmental change. The hydrological and carbon cycles are complex. My research focuses on developing tools and frameworks that help the scientific community interpret these isotope signals so that we can respond more effectively to a changing climate.
