Prior to joining Charles River in 2014, Tracey was a full-time faculty member at The Ohio State University where her research laboratory focused on immunopathology and early discovery immunotherapeutics laboratory evaluating immune and anti-inflammatory therapies in animal models of autoimmunity, immuno-oncology, and infectious diseases. She continues her involvement at OSU as an adjunct faculty in both the Colleges of Veterinary Medicine and Pharmacy in areas of mentoring, career development in industry, collaboration with biomedical research projects, and providing expertise in animal modeling for drug development in an online M.S. program in Translational Pharmacology.

Tracey is a diplomat of the American College of Veterinary Pathologists (ACVP) and holds both a DVM and a PhD in Immunology. Tracey has a strong publication record in immunology and pathology and is a current or past member of in numerous pathology, immunology, and immunosafety organizations including, the Society of Toxicologic Pathology, HESI-Immunosafety Technology Committee, American Veterinary Medical Association, the American College of Veterinary Pathologists, American Association of Immunologists, and American Association of Veterinary Immunologists. Dr. Papenfuss is the author of over 35 peer-reviewed articles and 10 book chapters and has presented at numerous national and international conferences on immunology, pathology, and immunotoxicology. Tracey has been a mentor for undergraduate, professional, and graduate students, residents/fellows, and post-docts and is interested in providing training and career development for future scientists in pathology and immunosafety.

He also provides investigative guidance and scientific leadership in pathology to local drug discovery teams, identify and lead collaborative mechanistic efforts with internal, external, consortia and academic investigators. 

Originally from Latin America, Vini was born in Brazil to Portuguese parents and retains dual nationality for the two countries. Academically, he completed formal Residency Training in Veterinary Pathology at Michigan State university, he holds a DVM and a PhD in Molecular Genetics and Environmental Toxicology from the University of Cincinnati. Prior to joining Janssen R&D, he was a Senior Pathologist at Vet Path Services (VPS in Mason, OH), where he spent almost 5 years serving as a Study Pathologist for nonclinical safety assessment studies. Prior to VPS, he spent over a year at MPI Research (now CRL Mattawan) as part of his combined training in Toxicologic Pathology.

Vini is a diplomat of the American College of Veterinary Pathologists (ACVP) as well as a diplomat of the American Board of Toxicology (ABT). He is very passionate about science of toxicologic pathology, with a strong publication record in toxicologic and comparative pathology, developmental and cardiovascular toxicologic pathology, and animal models of human diseases. He volunteers as a scientific reviewer for many peer-reviewed journals and is an active member of multiple committees in professional toxicology and toxicologic pathology organizations, within and outside North America, and is avidly invested in training and career development and outreach.
