Climates of the past, present, and future.

I am a Postdoctoral Research Associate at the Climate Systems Center, University of Arizona.

My research seeks to understand how Earth’s climate changes across annual- to centennial-timescales. I am fascinated by the intersection of climate across human and ecologic dimensions, during the past and into the present. I study the past because I am concerned about the future.

A major theme of my research is applying new quantitative techniques to understand climate using naturally derived “proxies”, for example from ice and sediments. I aim for a holistic approach by combining proxies with modern observations, physical models, and global climate simulations.

Previously, I received my PhD in climate science at the Massachusetts Institute of Technology (MIT) and Woods Hole Oceanographic Institution.
