About me

I’m a paleoceanography Ph.D. candidate in the School of Earth and Atmospheric Sciences at Georgia Tech. My research uses planktonic foraminiferal geochemistry to reconstruct ocean density and surface winds on glacial timescales. Understanding how the ocean-atmosphere system has changed in the geologic past is vital for projecting how it will respond to anthropogenic forcing.

I tackle this problem with statistical modeling, data science techniques, and machine learning algorithms. I both compile isotope data from existing sources and generate new data from coretop and Last Glacial Maximum sediments.

In my free time, I volunteer with Community Consulting Teams (CCT) Atlanta, a nonprofit focused on providing free consulting to local nonprofits. I have completed two projects with CCT Atlanta, working with Keep North Fulton Beautiful and Community Farmer’s Market.

Constraining Foraminifera Calcification Depths

Using foraminferal oxygen isotope data from the global tropics, I (with the help of my co-authors) investigated the calcification habitat for planktonic foraminifera. These freely floating microorganisms are very useful for paleooceanographic study, as long as we understand the depths at which they live and calcify. This work builds on previous global studies of surface-dwelling foraminifera (MARGO project and Malevich et al. 2019) and extends it to subsurface-dwelling foraminifera (G. tumida, N. dutertrei, and P. obliquiloculata). We present this new dataset and attempt to characterize trends in the calcification depth under various assumptions. Using a novel "TP" metric, we show that G. tumida has a calcification habitat independent of the thermocline depth, while N. dutertrei and P. obliquiloculata have calcification habitats that depend on the thermocline depth.
