Alyssa Chan

Alyssa Chan

Former Undergraduate Thesis Student

Alyssa is a senior concentrating in Chemistry and Earth and Planetary Sciences, with a secondary field in the Comparative Study of Religion. She joined the Johnston group in Summer 2014. Her thesis research involves evaluation of organic molecules as potential proxies for atmospheric oxygen isotopes.

Ben Cowie

Ben Cowie

Former Post-doctoral Fellow

Ben is an isotope geochemist with diverse interests in the Earth sciences. In the Johnston Group, he is currently exploring questions surrounding the evolution of the atmosphere and biosphere over the most recent billion years of Earth history using a triple-oxygen isotope approach.

He received his Ph.D. from the University of Calgary in 2013 for developing a novel stable isotope approach for characterizing oil sands reservoir fluids, and was awarded a Vanier Canada Graduate Scholarship for his work. From 2002 to 2008 he attended McMaster University in Hamilton, Canada where he earned B.Sc. and M.Sc. degrees in Earth and Environmental Sciences. His research during this time focused on compound-specific isotope analysis of lipid biomarkers with application to environmental remediation and monitoring. From 2006 to 2010 Ben was part of the Pavilion Lake Research Project team, a NASA Exploration Analog site, and an international collaborative research project. The project provides insight into the earliest life on Earth, and aims to change the way humans explore outer space.

Matthew Miller

Former Undergraduate Research Assistant
My work mainly focuses on establishing novel mineral proxies to track sulfur cycle dynamics in deep time, notably carbonate-associated sulfate (CAS). This system, alongside the robust yet infrequent barite record, potentially represents a powerful way to track sulfur and oxygen isotope behavior in order to constrain marine chemistry in the past. Additionally, I have started some culture work with the sulfate-reducing bacterium Desulfovibrio vulgaris, and am currently investigating the evolution of its isotope-fractionating metabolism.
