Research Interest

My major research and diagnostic interests involve diseases of avian and companion animals. Emergence of disease in these species is often the first indication of larger environmental problems and may foreshadow more serious events in ecosystems, human health and the health of domestic animals. Additionally, studies of naturally occurring diseases in these species can provide insight into the factors that predispose domestic animal and human populations to disease emergence. As a diagnostician I enjoy working with all species and am particularly interested in the comparative aspects of disease pathogenesis and diagnosis.

I have been intrigued with the biological interface between hosts and etiological agents, and the resulting patterns of morphological lesions, especially lesions caused by infectious disease agents. The morphologic, cytokine/chemokine, transcriptomic, proteomic and metabolomic patterns of host and pathogen responses provoke a series of fundamental queries like molecular pathogenesis of lesions, host genome manipulation of pathogen or vice versa, role of genomic pathology and systems biology in understanding infection biology with the basis for improved prediction of host and pathogen mechanistic genes and pathways critical to health and clinical illness. My research focuses on investigation of the comparative molecular pathogenesis of zoonotic intracellular bacterial pathogens in companion animals, development of vaccines and host gene expression-based diagnostics for zoonotic and select agent caused diseases, elucidation of genotype-phenotype relationships using computational and evolutionary genomics approaches. I want to develop computational tools and statistical tests to estimate key parameters of evolutionary processes that shape the sequence and expression variability and to apply theories to genomic diversity and divergence data in order to search for the signatures of selection in the genomes of different zoonotic and virulent microorganisms.

Diagnostic Skills

Histopathology, Immunohistochemistry, ELISA, Cell Culture, PCR, RT-PCR, Gel Electrophoresis, HA and HI Test, Cultural Sensitivity Test, Biological Sequence Analysis, Phylogenetic Analysis.



My primary role is teaching veterinary students. I enjoy interacting with the pathology and clinical courses with the goal of disease diagnoses and interpretation.
