My research is focused on the big influence that nanofeatures have on the evolution of our planet.  I combine fieldwork, petrology, and nano-geochemisty to investigate a range of questions ranging from ore geology, to cosmochemistry, to metamorphic petrology.

​

My main research these days lies in the formation of 'Invisible Gold' deposits, such as the Carlin type deposits in north-central Nevada. In these deposits gold can't be seen, even with high powered microscope, but is instead trapped in pyrite (aka fools gold).  I use a variety of nanoanalytical techniques, but specialize in using atom probe tomography (APT) to figure out how and why these important deposits form.

​

The incorporation of gold and other precious metals into pyrite is highly interesting, and has exciting possibilities as a source for the critical metals (i.e. Ta, W, Te, Ge, Co) that are desperately needed in Green Technologies. 

​

I currently am involved in projects looking at 'Invisible Metals' in North America (Nevada and Yukon Territory), China, and Europe.

​

Additionally, I am interested in ultra-high pressure and temperature metamorphism, specifically how microstructural clues can tell us the story of how these rocks returned to the surface.

​

My favorite mineral is quartz and my favorite rock is eclogite.

Don't hesitate to get in contact if you have any general question about APT, invisible gold, or UHP-T rocks.
