Research Interests: 

I am conducting a phytolith and pollen based paleoenvironmental reconstruction using 0-4 Ma paleolake records from East Africa in order to better understand the paleoenvironmental and paleoclimatic context of human evolution. Secondary research: I am developing and promoting the use of grass phytoliths as a precipitation seasonality proxy (e.g. summer, winter, monsoon) with an emphasis on southwestern North America.
