Dr. Troein holds a BA in Geosciences from Princeton University and a PhD in Earth and Environmental Sciences from Columbia University. She also served as a Crosby Postdoctoral Fellow in the Department of Earth, Atmospheric, and Planetary Sciences at MIT, where she led synchrotron-based research programs as the PI and Co-PI. These research programs studied natural carbon removal mechanisms that can be leveraged to remove anthropogenic carbon from the atmosphere.  

Dr. Troein was a former federal employee in the U.S. Department of Energy, where she served as a fellow at the Advanced Research projects Agency for Energy (ARPA-E). There, her work focused on innovations in carbon removal, sensor and model development for MRV, and alternative mining processes, and resulted in multiple $10M-$45M non-dilutive funding opportunities for startups and other innovators.

Dr. Troein was Head of Science at Isometric, a carbon removal registry, from July 2022 to September 2023. She led science strategy and vision-setting at Isometric through its $25M seed round, and she built and led the initial science team of 9 full-time scientists. Her team worked alongside Isometric’s engineering team to build and launch the Isometric Science Platform and the initial Isometric Science Network, with over 150 technical experts in carbon removal and its quantification.
