Post-doc | Dunn Lab
I am interested in the evolution of social traits, especially within societies of ants and other social insects.
Like the individuals that form them, societies themselves can have traits and features that are shaped by natural selection. Colonies have a lifespan, exhibit differences in division of labor, and respond adaptively to changes in their environment. Focusing on social insects, I am interested in how interactions within societies influence colony-level traits. I have studied social dominance hierarchies and queen determination in ants from southern India, how colonies respond to temperature change across the eastern United Sates, and how human activities influence ant communities in Manhattan, NYC. Beyond research, I have interests in writing about science for the public and developing projects in design.
