Title:Graduate Student, Department of Geological & Environmental Sciences
Primary Affiliation:
Office Location:Braun Hall (GeoCorner) 306B
Research Group:Paleobiology Lab


I am interested in Earth's ancient oceans and large-scale changes in marine biogeochemisty and ecology over geologic history.  My research broadly focuses on [1] biogeochemical cycling in ancient oceans, and integrating geochemical proxies to help better understand the dynamics of large environmental events; and [2] the controls on body-size evolution of marine organisms.  I am currently focusing on the end-Guadalupian extinction event (ca. 260 Ma), and the body-size evolution of foraminifera over the Phanerozoic.
