I am a PhD student in the Shanahan lab. I am broadly interested in using past climate to better understand the climate system and inform our knowledge for the future. I use a variety of biomarkers, such as GDGTs and alkenones as proxies for temperature and stable hydrogen isotopes in leaf waxes as indicators of hydroclimate changes.
I am focused on two main areas of research:
(1) Examining the last deglaciation in Southwest North America using a lake record from the Mogollon Rim in Arizona.
(2) Reconstructing sea ice in the Southern Ocean using biomarkers while simultaneously expanding the sea surface temperature calibration dataset.
