Coronavirus COVID-19

The V&E Program is following CDC, state, and university recommendations to practice social distancing in order to slow the spread of the novel COVID-19 virus. We have temporarily modified our operations to include teleworking options for our faculty, staff and graduate students, but remain available to serve you during regular business hours though email, phone and videoconference.
