Research Interests

Bacterial blotch is a common disease found in mushroom houses across the US, especially here in Pennsylvania. Blotch disease refers to a group of diseases that results in the formation of spots, discoloration, and sunken lesions on the mushroom cap.  A variety of Pseudomonas species have been identified as being the main causal agents of bacterial blotch, but the spectrum of pathogens causing this disease is still being explored.  

My research aims to identify the non-Pseudomonas species pathogens contributing to bacterial blotch in commercial mushroom houses in Pennsylvania and California. With greater insight on all key organisms involved in this disease, I hope to enhance current management practices targeting bacterial blotch in mushroom houses across the country.
