Function and Responsibilities:

Postdoctoral Scientist

Research Interests:

My research is centered around using molecular and nanoscale solid-state characterization techniques to elucidate reactions at mineral interfaces. Specifically, I focus on iron redox (geo)chemistry and its influence on (i) carbon cycling, (ii) nutrient availability and (iii) contaminant dynamics. I use state-of-the-art electron microscopy (S/TEM) and synchrotron-based X-ray techniques (XAS, PDF) to pinpoint and visualize these (geo)chemical reactions at the mineral interface. By doing so, I am able to derive a quantitative and mechanistic understanding of these key (geo)chemical interfacial reactions that are not currently possible with conventional laboratory techniques.
