Why I joined the ECS Ph.D. Program

 A strong interest in conservation science and the interdisciplinary program.

My research

My research is broadly focused on conservation science and reproductive biology. My thesis research is focused on the reproductive timing of songbirds through sex steroids, estradiol and testosterone, in conjunction with first egg lay date. A future project will focus on the potential trade-offs between immune function and sperm quality in male house sparrows.
