Davis Seelig


Assistant Professor
B.S., Boston University 1999
D.V.M. Tufts University 2003
Ph.D. Colorado State University 2010

Research Interests:
My research globally focuses on comparative and experimental pathology. Primarily, our laboratory studies the pathogenic mechanisms of infectious prion diseases using the cervid-origin prion disease Chronic Wasting Disease as a model. Chiefly, we seek to understand: 1) the mechanisms by which a mis-folded protein becomes infectious, 2) the pathways linking the accumulation of mis-folded protein with neurodegeneration, and 3) the systemic metabolic consequences of protein-misfolding disease. In addition, we are interested in advancing and refining the approach to the diagnosis and classification of canine lymphoproliferative disease.
Clinical Interests:
My primary clinical interests are expanding the toolset available to diagnostic veterinary cytopathologists and improving the ability to diagnose hematopoietic neoplasia. 
Instructional Areas:
My primary teaching activity takes place in the core, second-year DVM clinical pathology course, where I lecture on hematopoietic neoplasia.
