My research as an MSc student is focused on using zircon U-Pb geochronology and geochemistry combined with apatite Rb-Sr isotope systematics to investigate the evolution of the Archean crust. I am analyzing samples that cover the timespan of the Archean, and include some of the oldest known terrestrial rocks from the Acasta Gneiss Complex, Northwest Territories, as well as samples from southwest Greenland and central India. The integrated approach of using the Rb-Sr system as an indicator of crustal composition with the robust zircon U-Pb geochronometer allows me to explore how and when continental crust may have first formed on our planet.
I have been a TA for the following courses at UBC:
EOSC 323 Structural Geology I
EOSC 221 Introductory Petrology
EOSC 322 Metamorphic Petrology
EOSC 328 Field Geology
