Following the merger of the Mammoth Cave prototype I&M program with the Cumberland Piedmont Network, I served as co-coordinator of the network from 2007 to 2008. From 2001 to 2006 I was the coordinator of the prototype program. Prior to that, I was a nongame wildlife biologist with the Kentucky Department of Fish and Wildlife Resources, and a biotech with the Montana Department of Fish, Wildlife and Parks. My interests include wildlife ecology, endangered species conservation, cave ecology, running, backpacking/hiking, bicycling, and family.

Primary Network Responsibilities: Forest vegetation monitoring support. Project lead for invasive species early detection monitoring.
Active Projects: Invasive Species Early Detection, Forest Vegetation Monitoring
Education and Areas of Expertise:
BS, Forest Science, University of Wisconsin
Certificate in Environmental Studies, University of Wisconsin
I started out as an intern for the CUPN in 2011, primarily serving as a field assistant for forest vegetation, cave bats, and cave crickets monitoring. I began assisting with vegetation monitoring data management for the network in 2013 and officially joined the network in 2016. I have a background in forest ecology and conservation, and have also served as a natural resources intern for Mammoth Cave National Park, a conservation intern for Natureserve, and a botany field technician for the University of Georgia. Besides monitoring, I also assist with maintaining CUPN park species lists and publications in the Integrated Resource Management Applications (IRMA) Portal, which provides easy access to National Park Service applications that manage and deliver resource information to parks, partners and the public.

I studied the mathematical relationship between air temperature and wind patterns in parts of Mammoth Cave as part of my thesis work. Then, I worked as an Instructor of Mathematics at Western Kentucky University. I have since been working with the Cumberland Piedmont Network and also collect surface air quality data at Mammoth Cave National Park. I enjoy listening to music, watching movies, reading, riding roller coasters, bicycling and hiking.

Prior to working for CUPN, I started my career with the park service at Mount Rushmore as an interpretation ranger in 1997. From there I spent two seasons at Sleeping Bear Dunes National Lakeshore in various divisions; including interpretation, fee collection, maintenance, firefighting and dispatch. My last season before I ended up at my home park of Mammoth Cave National Park (MACA), was spent on Little Cranberry Island at Acadia National Park. I worked at MACA as a temporary secretary for the Science and Resource Management division. I was then hired on at MACA for a six month Student Conservation Association (SCA) GIS intern. Once my SCA position was complete, I was put into a student program currently called NPS Pathways. I then attended Western Kentucky University and completed my GIS Certificate program in 2002. After which I became a 50/50 split GIS Specialist for CUPN and MACA.
