I am a Lamont Assistant Research Professor and principal investigator of Microbial Evolution and Biogeochemistry Laboratory at Lamont-Doherty Earth Observatory of Columbia University. My research focuses on determining the physiological responses of marine microbes to past and future climate change. My expertise lies in precisely controlled laboratory culturing techniques including experimental evolution, chemostats, photobioreactors, and manipulation of carbonate chemistry. I additionally use geochemical tools to develop proxies based on microbial biosignatures that record environmental change and biological innovations through Earth history. Prior to joining LDEO, I completed my postdoctoral training at the University of Colorado Boulder after receiving my Ph.D. from the Department of Earth and Planetary Sciences at Harvard University in 2017.

I am an Earth and Environmental scientist specialized in climate change and carbon cycling. My expertise encompasses marine geology, paleoclimate research, isotope geochemistry, and molecular analysis of organic matter. My postdoctoral research at the Lamont-Doherty Earth Observatory centers around the Arctic carbon cycle, the Arctic Ocean carbonate system, and ocean acidification in relation to historical and current climate change. My work involves reconstructing seawater pH and pCO2 in Arctic sediment cores by analyzing B isotopes and trace elements in planktic foraminifera.

I am a research scientist specializing in organic geochemistry and microbial ecology. In my current appointment as a Postdoctoral Research Fellow at LDEO I am working with Dr. Sarah Hurley and Dr. Sonya Dyhrman researching the physiology of phytoplankton under future ocean conditions. I am broadly interested in ocean organic carbon cycling and molecular tools to examine it.

Anna is a sophomore at Columbia College studying Climate System Science. Born and raised in Shanghai, China, she loves attending classical music concerts, playing rugby, cycling on the 9W Highway, and cooking traditional Chinese dishes. Since Summer 2024, she has worked on analyzing the seasonal and geospatial patterns of geochemical ocean conditions in areas of high phytoplankton productivity. She is eager to learn more about computational and statistical oceanography, as well as keeping phytoplankton alive!

I am an assistant professor of environmental science in the Natural Sciences department at Baruch College, City University of New York. At Lamont, I am an INSPIRE Fellow collaborating with Sarah Hurley within the Microbial Evolution and Biogeochemistry group. My research is laboratory-based and uses the tools of stable-isotope biogeochemistry to ask questions relevant to microbial ecosystems. Currently, I am most excited about how Cyanobacteria allocate their fixed carbon both within and outside their cells, in planktonic and mat-forming communities. Prior to Baruch, I was a Visiting Assistant Professor in the Geosciences department at Williams College, received my Ph.D. from Harvard University, and was an undergraduate student at Columbia/LDEO. As a former first-generation college student and proud Latina scientist, I am keenly aware of the need for a more inclusive environmental science community, and this context is always at the forefront of my teaching and research.
