Nathan is a Fisheries Biologist at the Ellensburg office and has experience in a variety of ecological topics. As an undergraduate obtaining a degree in ecology, Nathan studied abroad in Australia and took a marine ecosystem course. This sparked his research interest and upon returning was accepted as a Research Experience for Undergraduates intern with the National Science Foundation with whom he conducted avian research at Mississippi State University. While an ecology graduate student at St. Cloud State University, Nathan had the opportunity to travel Minnesota for three summers leading a field crew conducting endocrine disruption research. This involved collecting a variety of fish species from which he drew blood and preparing liver and gonad sampling for histological analysis. He also took water samples, deployed and retrieved passive water samplers, caged fathead minnows at sample locations, and participated in many laboratory chemical exposure experiments. While Nathan’s focus has been in endocrine disruption and it’s implications, he is very interested in a variety of ecological concepts and is eager to continue learning.
