I am interested in understanding how the climate system responds to different forcings and under varying background climate states, with the goal of improving our predictions of future climate changes. My PhD research is focused on the use of organic geochemical (GDGTs, leaf wax) and stable isotope (C, H) proxies to reconstruct changes in climate in northeastern Mexico and the southern US Great Plains on orbital to millennial timescales. I also work with paleoclimate model experiments to infer complex climate dynamics of the past.
