About Robert J Ossiboff

I am a board certified veterinary anatomic pathologist, virologist, and molecular diagnostician with a primary professional focus on increasing the breadth and depth of knowledge of diseases of wildlife with special emphasis on reptiles and amphibians. Through a combined understanding of the fundamentals of disease pathogenesis, pathogen biology, disease pathology, and molecular/cellular biology, I approach animal disease investigations from multiple angles in an attempt to completely characterize disease conditions. My ultimate goal is to broadly impact the health of both captive and free-ranging wildlife through pathogen research and discovery, the creation and distribution of novel reagents, and the dissemination of knowledge.

Research Profile

Much of my basic science research is driven by diagnostic submissions and increasing the availability of basic science reagents for use in wildlife species. Current research projects include i) establishing in vitro tissue culture cell lines from non-domestic species for basic science research and discovery, ii) characterizing serpentoviruses (nidoviruses) – an important and emerging group of reptilian viruses, iii) studying the pathogenesis of Batrachochytrium spp. infections in amphibians, and iv) the characterization and classification of novel infectious diseases of reptiles and amphibians.
