Sarah Cobey

I'm a doctoral candidate in ecology and evolutionary biology at the University of Michigan.

Main interests

• Ecology and evolution of infectious disease
• Evolutionary accessibility and levels of selection
• Robustness in evolution and ecological-evolutionary dynamics
• Model complexity: When to drop scales, discretize/use continuous approximations, include/exclude networks, finite/infinite populations

Expertise
I've had meaningful encounters with:

• Nonlinear dynamical systems
• Adaptive dynamics
• Methods in bioinformatics (ML and Bayesian phylogenetic analysis, codon models)
• Agent-based modeling and genetic algorithms
• (working on this one) Fitting nonlinear stochastic dynamics

What I hope to get out of the CSSS

• I'd really like to learn more about financial models,
• ... questions in social science, and
• ... neat, new quantitative methods.
• I'd also really like to strengthen my foundations in network theory, dynamical systems, modeling, etc.

Possible projects

• One fun problem is how heterogeneity in hosts' immune responses might mediate competition among pathogens. What kinds of behaviors (chaos, cycles, etc.) result when some hosts view different pathogens as identical? (This problem happens to be biologically grounded!)

• I'm also excited by public goods games and parasitism gone bad (cooperation).

Other interests
Board games, card games, hiking
