Ana Gonzalez-Nayeck is an assistant professor of environmental science in the Natural Sciences department at Baruch College. Her research is laboratory-based and uses the tools of stable-isotope biogeochemistry to ask questions relevant to microbial ecosystems. Currently, she is working on using stable isotopes to measure how photosynthetic microbes distribute carbon within their cells and microbial ecosystems. Prior to Baruch, she was a Visiting Assistant Professor in the Geosciences department at Williams College. She completed her Ph.D. under the supervision of Dr. Ann Pearson in the Earth and Planetary Sciences department at Harvard University, and completed her undergraduate work at Columbia University, where she conducted research at Lamont-Doherty Earth Observatory.
As a former first-generation college student and proud Latina scientist, professor Gonzalez-Nayeck is keenly aware of the need for a more inclusive environmental science community, and this context is always at the forefront of her teaching and research.
