Responsibilities and Interests:

I am the extension specialist in forage production and utilization. This involves both annual and perennial forage crops and their interaction with consuming animals. In this role, I collaborate with agencies and organizations throughout Pennsylvania and the Northeast that have forage related interests. My research is primarily oriented towards the production and utilization of conserved forages. Emphasis currently focuses on issues (seeding methods, rates and dates, weed control, disease control, fertility, seed treatments, and seedling management) associated with forage establishment.

My interests include “Triathlon Racing”.
