Liz is an Extension Educator serving grain, hay, and silage producers in Dauphin and Perry Counties.   

Originally from Chester county, Pennsylvania, she earned her undergraduate degree from Hampshire College in Organic Chemistry and Plant Science and her Ph.D. from Penn State in Entomology.  From 2011 to 2013, at the University of Wisconsin and the USDA’s Agricultural Research Service, she worked with cranberry growers to develop integrated pest management tactics for the red-headed flea beetle.  For the next two and a half years, in the Department of Agronomy at the University of Wisconsin, she worked with grain farmers on weed management strategies for pigweeds, herbicide resistance management education, and cover crop resources.
