Research Interests

I study the crystal structures and chemistry of minerals formed under varying conditions in order to answer questions in Environmental Mineralogy, Biomineralization, and Gem Science. My current focus is on bio- and geo-formed carbonates (aragonite, calcite) and amorphous silica (opal, glass).
