Service:

As the director of the Molecular Diagnostic Laboratories (MDL) in the Kansas State Veterinary Diagnostic Laboratory (KSVDL), I oversee the molecular diagnostic services that the KSVDL offers its clientele.  I directly supervise 5 staff personnel (4.5 FTE) in the MDL.  The MDL at the KSVDL offers polymerase chain reaction (PCR) testing capabilities for many bacterial and viral targets using traditional PCR methods, real-time PCR methods, multiplex assays, and have recently began to offer  a species specific panel, i.e., bovine respiratory panel that targets 7 viral targets and Mycoplasma bovis.  The MDL has been a participant in the National Animal Health Laboratory Network (NAHLN) and involved in screening surveillance testing for selected high impact disease agents, and foreign animal diseases using real-time PCR methodologies.  Our involvement in the NAHLN has allowed the lab to be a leader in developing and validating high throughput real-time PCR procedures in collaboration with other NAHLN labs and USDA, and in developing and leading individual hands-on training programs for personnel in other NAHLN laboratories across the USA to operate and complete high throughput real-time PCR procedures. 

Research:

The goal of my research is to develop and validate automated, user-friendly, high-throughput nucleic acid-based detection systems for veterinary diagnostic, environmental and food safety applications.  I believe this process will require interdisciplinary collaboration and partnering.  Currently funded collaborations include:  National Animal Health Laboratory Network/USDA APHIS; Applied Biosystems/Life Technologies; US Army’s Natick Soldier Systems Center.

Instruction:

I am the course coordinator for the Veterinary Virology (DMP722) course offered in the second year of the veterinary medical curriculum at Kansas State University.  I also give a lecture every three weeks on current and future molecular diagnostics applications/trends to the fourth year students in the necropsy rotation (DMP785).
