For the first half of his career, Evan was a diagnostic pathologist at the Purdue Animal Disease Diagnostic Laboratory, where his main role was to facilitate the University’s residency program in veterinary pathology and to mentor graduate students in their research projects. In 2002, Evan joined Bristol Myers Squibb’s Discovery Toxicology organization as a Principal Veterinary Pathologist. In 2008, he assumed the role of Director of Pathology. He and other veterinary pathologists in his group provide critical scientific input for Discovery Working Groups at every stage of the Company’s drug discovery process.


Among other honors, Evan has been recognized by Bristol Myers Squibb’s Research and Development (R&D) organization for his contributions to several drug discovery and development programs. He has published and presented extensively in his field. Evan has served the American College of Veterinary Pathologists in numerous capacities, including Councilor and Certifying Examination Chair.
