Research Interests

I study ocean oxygenation, particularly in tropical oxygen minimum zones (OMZs), areas with very low oxygen concentrations that have been expanding in response to recent climate change. I'm interested in the interactions between ventilation (ocean circulation, stratification), water column structure, and productivity as they relate to oxygenation. My dissertation focuses on reconstructing how OMZs responded to warming during the Miocene Climatic Optimum, when temperature and atmospheric pCO2 was similar to what is projected for the next 100 years. Using multi-proxy approach that includes trace elements and isotopes in planktonic and benthic foraminifera allows me to reconstruct not just oxygenation, but the things that affect it. I'm always excited to meet potential collaborators so if you're interested in similar problems, please reach out!
