My research goal is to understand the physiological mechanisms of behavioral plasticity in organisms. I apply an integrative approach that includes molecular, subcellular, and systemic levels of biological organization. I investigate endocrinological mechanisms by which neural, sensory and motor systems adapt to a changing external environment. I use in vitro and in vivo biochemical manipulations, molecular assays, hormone measurements, in-depth behavioral analyses, and measures of reproductive success to assess the hormonal regulation (in both long-term and short-term) of reproductive phenotypes of free-living and captive species of songbirds and fish. While I am trained as a neuroendocrinologist and most of my work involves neural mechanisms in the context of regulation of social behavior, I have developed interests in other local signaling mechanisms in specific tissues (e.g. reproductive tissues, muscle, spinal cord) that either undergo dramatic changes associated with life history or functional specialization. I plan to further my research in studying neural, muscle, and reproductive physiology in males and females of two species of animals that undergo dramatic changes in life history stages and body-wide transformation during adulthood.
