Research Interests

I develop mathematical, computational, and conceptual models to study natural selection and the evolution of organismal design. My work makes testable predictions on topics ranging from microbial life history to sociality to cancer. My study of particular topics leads to syntheses of natural selection, robustness in relation to biological design, and the commonly observed patterns that emerge from information flow and scale.

Current projects: (1) Microbial life history: the fundamental forces of biological design, (2) Evolution of regulatory control, and (3) Invariance and the common patterns of nature.
