Scanning electron microscopy and synchrotron x-ray imaging are powerful tools for studying developing tooth enamel.
The ephemeral Kokiselei laga in Turkana, Kenya, is the site of important fossil remains that contain clues about the environment and climate of sites of hominin occupation.
Computational optimization routines can be combined with detailed study of tooth isotope chemistry, mineralization, and physiology to reconstruct patterns of past seasonal hydrology.
We have corroborated synchrotron imaging findings with scanning electron microscopy. This technique allows us document the magnitude of oxygen, calcium, phosphorus and carbon deposition in secretory and maturation matrices during molar mineralization.

An important part of my research has included fieldwork in the Turkana Basin, and serving as a teaching assistant for the Turkana Basin Institute (TBI)'s Field School. Here, Lothagam sandstone deposits viewed by students during Craig Feibel's geology class taught at TBI Turkwel in Turkana, Kenya.

I have served as a resident tutor at Eliot House for 4 years, providing support for students seeking fellowship and other funding sources, and advising students in Human Evolutionary Biology.
