Research Interests: 

I am generally interested in phenotypic plasticity, how it is constrained by the environment, and the trade-offs involved. I study these concepts in insect cuticular melanism which is often a plastic trait. In particular I am researching how diet composition influences the expression of melanism and how this varies across populations.
