Teaching Experience

At The Pennsylvania State University – University Park Campus

  • Guest lecturer for PPEM405 Microbe-Plant Interactions
  • Teacher assistant for AGECO12 Plant Stress: It's Not Easy Being Green   
  • Instructor for BIOL127 Introduction to Plant Biology - Laboratory section 002               

Extension Experience

Currently, I am using multilocus sequence analysis to characterize the population structure of individual and regional outbreaks in order to design new management tools and provide growers with the data they need to control the disease

Translate Dr. David Beyer's extension work into Spanish for mushroom growers at the Annual Extension Event in Chester County.
