Daniel Sigman is Dusenbury Professor of Geological and Geophysical Sciences at Princeton University.  He studies the global cycles of biologically active elements, in particular, nitrogen and carbon, and he is active in the development of natural abundance stable isotope techniques for studying nitrogen in the environment, with a focus on the ocean.

He also investigates the history of biogeochemical cycles in order to understand the causes of past changes in the atmospheric concentration of carbon dioxide, the role of this greenhouse gas in the waxing and waning of ice ages, and the ocean’s response to climate change. This Earth history work largely involves the isotopic analysis of the organic matter bound within the fossils found in marine sediments.

Sigman received a B.S. from Stanford University in 1991 and a Ph.D. from the Massachusetts Institute of Technology/Woods Hole Oceanographic Joint Program in Oceanography in 1997. His honors include the Macelwane Medal of the American Geophysical Union (2004), the Bessel Award of the Humboldt Foundation (2004), a MacArthur Fellowship (2009), the Science Innovation Award of the European Association of Geochemistry (2012), and the Graduate Mentoring Award of Princeton University (2015).
