Dr. O’Brien and a Red Poll (Acanthis flammea) on the North Slope of Alaska
Courses Taught:
BIO 322 Anatomy & Physiology, BIO 160, and an assortment of specialized upper level BIO courses.
Scientific Areas of Interest:
physiology, endocrinology, neuroscience, reproduction, ecology, evolution, sustainability, toxicology, and conservation
Research Interests:
Broadly, my research could be characterized as how organisms react to a dynamic environment; meaning, how does an organism's physiological processes allow it to react to environmental changes, both natural (seasonal changes, food abundance changes, social changes, etc.) and non-natural (global warming, pollutants, human disturbance, etc.). I usually work with a variety of vertebrates including birds, fish, amphibians, reptiles, and small mammals. I am specifically focused on the mechanisms of reproduction and what factors influence an organism’s reproductive physiology.
Undergraduate Research:
I welcome working with undergraduates on novel research projects. Students should contact me to determine if I have an opening in my lab and if there is room to work on an established research project or develop one of their own. To be successful in my lab a student will need to have a strong work ethic, fine attention to detail, the ability to work odd hours (including weekends and early mornings when needed), the ability to do field work (including in inclement weather), a positive attitude and a sense of humor.
