My work spans four broad areas of inquiry:
(1) Quantifying biological drivers of plant and insect population dynamics: I use stage structured population models to identify key factors shaping population dynamics.
(2) Optimal decisions in behavior and life history: I use mathematical models predicting ultimate causes for the evolution of specific phenotypes.
(3) Transient dynamics: Traditional models focus on long term (stable) dynamics, and ignore the often dramatically different transient dynamics that happen before the system stabilizes. Recently there is increasing recognition that frequent disturbances like fire or drought prevent populations in many systems from reaching stable dynamics.
(4) Population management: My research evaluates alternative perturbation methods for stage structured population models; perturbation analysis is the cornerstone for identifying which life history stage should be targeted to most effectively reach one's management goal.
