Project title: In silico isotopic tracking of the metabolic evolution in the sulfate-reducing microbe D. vulgaris
Project description: The history of oxygen in Earth's atmosphere can be read in the variation of sulfur isotope ratios in ancient rocks. Variations in these isotopic tracers are taken to reflect differences in the global vigor of sulfate-reducing microbes. These differences, in turn, are taken to reflect variability in oceanic sulfate abundances. The final step in the deductive sequence links oceanic sulfate levels to weathering rates of sulfide minerals through a direct proportional relationship mediated by atmospheric oxygen. Despite the importance of this chain of logic to current thinking on the history of atmospheric oxygen levels, the critical link that ties it all together - the isotopic effect associated with microbial sulfate reduction - remains empirically validated but mechanistically obscure. This research project aims to make clear the specific metabolic controls on isotopic fractionation during microbial sulfate reduction, with the broader goal of revealing the co-evolution of microbial sulfate reduction and Earth's surface environment.

The specific objectives of this research project will be to: (1) use MATLAB to reproduce a recently published in silico model of the genomically-constrained core metabolism of the sulfate-reducing microbe Desulfovibrio vulgaris; (2) modify the model to include the thermodynamic fractionation of sulfur isotopes at key metabolic steps; and (3) explore the range of net sulfur isotope fractionations produced by biologically-relevant variations in the control parameters for the D. vulgaris metabolism.
Prerequisite: 1 term completed at McGill + CGPA ≥ 3.0; or permission of instructor.
Other prerequisite, if applicable: If applying from the biological sciences, a strong desire to quantify biogeochemical processes. If applying from the physical sciences, a strong interest in the nuts-and-bolts of the history of life. MATLAB experience would be helpful.
Grading scheme (The final report must be worth at least 50% of final grade): 50% of final grade based on participation in lab meetings and 1-on-1 meetings with advisor; 50% of final grade based on final report
