Administration

I serve as a liaison between Department faculty and staff and the Dean. I consult with faculty and staff on a regular basis and represent the department in the Administrative Council. Major administrative duties include the following: Guidance of all professional activities of the faculty, staff, residents and graduate students of the Department; development and implementation of Departmental policies and procedures as required by the College and the University; promotion and development of independent or collaborative research, teaching and service programs; preparation of an annual budget in consultation with Chief Financial Officer, Business Office and faculty for the Department; fiscal management and accountability of the Department; preparation of annual reports summarizing all activities of the Department; conducting regular faculty and staff meetings to facilitate faculty and staff input on various issues, and to establish better communications at all levels; performance evaluation of faculty and staff; recruitment of faculty, staff and residents to the Department; preparation of documents for tenure and/or promotion of faculty and staff; maintain Departmental inventory of equipment and space; and providing and creating opportunities for faculty and staff growth and development.

Research

My primary research interests are to study and understand the pathogenesis of important infectious diseases of animals, and to develop strategies to protect animals from these diseases. Identification, molecular characterization and functional analysis of antigen/toxins of Streptococcus suis, Mannheimia haemolytica, and Fusobacterium necrophorum are my primary research focuses.

Teaching

I coordinate and teach a portion of the professional Veterinary Bacteriology and Mycology course to sophomore veterinary students. This is a 4 credit hour lecture and laboratory course. The course is designed to provide the latest information on all facts of the microbial pathogens of animals of veterinary interest.
