My research focuses on the function and evolution of ornamental traits in birds and on the co-evolution of hosts and pathogens.  Research on these broad topics has led my students and me to adopt approaches ranging from behavioral ecology and phylogenetic reconstruction to immunology, parasitology, proteomics, and functional genomics.  I teach ornithology and a graduate class in evolution every year and I periodically teach undergraduate evolution.
