Originally from Massachusetts, Christina came Virginia Tech in November 2006.  After receiving her Bachelor’s from Penn State, Christina completed her Master’s degree at the University of Guelph and then her doctoral degree at Ohio State.  Although she attended two Big 10 schools, there is no doubt her allegiances lie with her true alma mater.  Christina’s research and extension goals focus on improving milk quality through reducing mastitis and improving animal well being.  More specifically, she is interested in identifying environmental sources of the mastitis-causing pathogen Enterococcus spp.  Furthermore, her research efforts have begun to examine ways to detect disease prior to onset of clinical signs as a way of improving animal well being.  Christina also maintains an active milk culturing laboratory to aid in both her research and extension efforts.   The milk laboratory led to several extension programs focusing on the importance of milk culturing and teaching producers how to use the results to become more profitable.  Other extension efforts have related to testing milking equipment and improving parlor efficiency.  Outside of the office, Christina enjoys spending time with her sons and husband, photography and showing Labrador Retrievers.
