Passion for the Profession

Katie’s passions from a young age have always been in natural sciences, whether it was helping the neighbors in their gardens or collecting and identifying rocks on Lake Michigan.  Wetland science is where her loves for geology and biology intersect.  Wetlands are diverse, complicated, and fascinating systems.  To understand them it is necessary to investigate not only current conditions, but also the natural history and local history/use of the site.

Outside Interests

In her free time, Katie volunteers at the Morton Arboretum in the Woodland Stewardship program, and assists in a local animal rescue.  Her hobbies include hiking, biking, rock tumbling, and cooking.
