Research
Interests:
Understanding
the impacts of
diseases on wildlife populations and the potential for these species to
act as reservoirs or sentinels for livestock, poultry, and human
diseases represent the central missions of our lab. Most of my
current work is oriented towards the epidemiology of viral and
vector-borne diseases specifically bluetongue and the epizootic
hemorrhagic disease viruses in white tailed deer, avian influenza
viruses in free-living duck and shorebird populations; vesicular
stomatitis virus vector and contact transmission; West Nile virus in
peridomestic avian species; and Ehrlichia chaffeensis in white-tailed
deer. Specific research objectives are variable reflecting
the multi disciplinary mix of our immediate group and an abundance of
intra- and extramural collaborative opportunities and range from
improving basic and molecular diagnostic tests, understanding
pathogenesis, development of sentinel systems involving wildlife,
understanding mechanisms involved in pathogen transmission and
persistence, to molecular epidemiology.
