Jen and her family have been residents of Elk Township since 2011 and have enjoyed hiking, recreating and fishing along the Big Elk and Little Elk Creeks.

Jen received a degree in Zoology from Colorado State University and then studied the ecology of Atlantic Salmon in Norway for her Master’s degree. For her Ph.D. work she researched wild cat species in Indonesia, but retained a strong interest in aquatic ecology. Jen is currently an Associate Professor in the Biology Department at Lincoln University where she teaches various courses in the fields of Ecology and Environmental Science. While her own research is still focused on the conservation of wild cat species internationally, she has worked with students locally to assess water quality in the Little Elk Creek as well as several other ecological projects within the watershed. Jen joined the board of the Elk Creeks Watershed Association in 2023.
