Research Interests
Understanding how wildlife cope with anthropogenic environmental changes, specifically urbanization. Particularly interested in the physiological, behavioral, and morphological phenotypic modifications to urban environments in addition to the adaptive developmental mechanism of maternal effects. Uncovering how urban-specific environmental pressures influence wildlife populations to create relevant conservation initiatives for city planners.
