 Kelly Muth    

I have been working with Dr. Rosemary Sherriff since 2011.  As a geography student (BA 2012), I was both a teaching assistant for Physical Geography and an undergraduate research assistant in the Dendroecology Lab. I've continued to work as a lab technician in the Dendroecology Lab part-time since 2011.  My work includes dendrochronology, climate analysis and database management.
