Other

Research Interests: The use of non-invasive methods to gain a fundamental understanding of reproductive biology across multiple species, which can serve as reference to assess the impact that environmental toxicants or stressors can have on hormonal changes, reproductive development, pregnancy, and immunological health and disease in animals and humans.

Teaching Interest: Reproductive biology from a conservation perspective, including comparative anatomy, physiology, and endocrinology among terrestrial and marine mammals.
