Dr. Christopher Spencer is a geologist and Associate Professor in the Department of Geological Sciences and Geological Engineering at Queen’s University in Kingston, Ontario. His research is rooted in fieldwork and utilizes igneous petrology, geochemistry, and geochronology to understand orogenic processes and secular change of geologic processes spanning 4.5 billion years of Earth history. Current projects use stable and radiogenic isotopes coupled to igneous geochemistry as a tracer for modern tectonic processes along with tracking the oxidation of the atmosphere and its reflection in the geologic record. Chris was awarded the Geological Society of America Young Scientist Award (Donath Medal) in 2020 and a John Curtin Research Fellowship in 2015. He holds a Ph.D. in Earth Science from the University of St Andrews (Scotland) and a B.Sc. and M.Sc in Geological Sciences from Brigham Young University (Utah).
