Research in the Williams Lab is taxonomically broad and highly interdisciplinary, spanning from molecular biology to population ecology. We focus primarily on systems characterized by high seasonal or inter-annual variability in resource pulses, with the goal of advancing our understanding of the mechanisms that underlie inter- and intra-specific variation in daily and seasonal timing. To explore the ecological and evolutionary drivers (and consequences) of this variation, we complement studies of free-living populations with lab- and field-based experiments and use a variety of tools including metabolic tracer techniques, molecular assays, gene-expression studies, and biologging. Below are some examples of current/recent projects in the lab.
