Molecular Diagnostic test development and validation

My research focus is to develop and validate PCR-based molecular diagnostic assays for use in routine diagnostic setting to detect veterinary pathogens and those of zoonotic importance. My special interest lies in development of molecular-based detection assays to identify vector-borne veterinary pathogens. In addition, I am highly interested in developing organ system specific, multiplex PCR panels targeted to common pathogens capable of causing diseases in a specific organ system. 

Collaborative research

I participate in clinical and collaborative research activities involving pathologists and clinicians at Kansas State University to identify the cause of an unknown illness using molecular approaches with a goal of translating basic molecular knowledge to the actual practice of clinical medicine.

In addition, I work on molecular diagnostic projects collaborated with industry partners. These projects are primarily intended to develop and validate real-time RT-PCR based assays to diagnose a variety of veterinary pathogens including those of zoonotic potential.  


I participate and oversee daily diagnostic activities at Kansas State Veterinary Molecular Diagnostic Laboratory (KSMDL). I also involve in client consultation involving PCR-based detection assays.
