WELCOME!

I'm a full professor of Economic Geology and Geochemistry at the Geology Department, Universidad de Chile. I am also the Acting Director of the Millennium Nucleus Center Metals Tracing along Subduction (NMTM) and I oversee the CEGA Mass Spectrometry and Geochemistry Labs.

My research interests are diverse including geochemistry of ore deposits, isotope geochemistry, geochronology,  mineralogy, metallogenesis and Andean geology. I combine field studies with geochemical tools including mass spectrometry and electron microprobe analysis to understand geological processes. For more information, please check my Research and Publications pages.  

If you are interested in research opportunities in my group, please contact me
