Tiny ocean dwellers witnessed climate cycles, report past conditions

Research Interests

My core interests and experiences center around how things (e.g. water, methane, carbon, other elements) move at regional to global scales; how these movements are intertwined with changes in tectonics, atmosphere, ocean, and climate; and how the biosphere evolved with these changes through Earth history. Since arriving at Syracuse University in 2011, I have been building a research program highlighting (1) global marine environmental changes through Earth history, (2) local and state-wide fresh water quality issues evolving with the adaptation to climate and energy challenges. Both directions fall into the broadly defined theme: co-evolution of life and planet.
