I'm involved in several related projects focused on detrital geo- and thermochronology from fluvial to deep-sea fan systems of North and South America.

I'm also interested in quantifying the erosional response of normal fault blocks to tectonic and climatic forcing in the American west using cosmogenic nuclides in detrital sediment.
