My current research involves improving hatchery-origin fish to be more phenotypically similar to wild fish for tagging studies and reintroduction efforts. Current projects I am involved in are evaluating smolt quality assessment indices, determination of adult life history strategy in juveniles, and morphometrics.

Due to my broad interests, my life (academic and otherwise) has followed a winding path. I started at Michigan State University studying Zoology and interested in animal behavior and neurobiology but studying abroad in the Galapagos Islands inspired me to concentrate in Marine Biology. During my undergraduate studies I worked as a wildlife educator for Michigan United Conservation Clubs and as a student manager at the University of Illinois Wildlife Medical Clinic. Following graduation I moved to Urbana-Champaign, Illinois and began working as a technician for the Department of Animal Biology and the Department of Natural Resources and Environmental Sciences at the University of Illinois. I also worked as a technician for the Illinois Natural History Survey at Kaskaskia Biological Station. After gaining real world experiences I returned to school to earn my master’s degree at Mississippi State University. My research focused on stress physiology in fish (thermal, salinity, handling, etc) and comparative transcriptomics. Before coming to Oregon to begin my work on salmonids I worked as a research assistant with Memphis Zoo conducting research on reproductive physiology of amphibians.

Outreach and Extension
4-H STEM club leader, FabFems mentor, and American Field Service Intercultural Programs liaison and returnee ambassador.
I am trained in horse whispering (natural horsemanship), my great-grandfather was a lion tamer, and my great-aunt trained dogs, horses, and primates. While working as a wildlife educator I have also trained mink, porcupine, opossum, mice, raven, bald eagle, wood ducks, various falcons and owls. At home I work with my cat, dog, and salamander to teach them tricks in order to stimulate their minds and enrich their lives.
