Growing up outside of Chicago, near the Brookfield Zoo, Dr. ElizabethLiz Rozanski developed a love for veterinary medicine from age five. As a member of the Foster Hospital for Small Animals' Emergency and Critical Care team, she treats animals at one of the nation's busiest academic emergency rooms. She is board-certified in both internal medicine and emergency and critical care.

Dr. Rozanski graduated from the University of Illinois with her DVMdegree. After completing a residency in Philadelphia, she was drawn to Tufts by the position's combination of research, teaching, and service. She teaches toxicology and respiratory medicine throughout the four-year Cummings School DVM curriculum, and lectures in others. I love the students, she says. They are a continued source of inspiration and enthusiasm.

She has also been involved in student efforts to provide free rabies vaccinations in low-income housing in the City of Worcester, serves as a faculty mentor for summer student research projects, has raised funds for the American Heart Association (with her dog, Brie, named after one of her favorite cases at the Foster Hospital) through the Central Massachusetts Heart Walk, and lectures often at continuing education and community events. She is also the past president of the Veterinary Comparative Respiratory Society.

Dr. Rozanski's primary research interest is in respiratory function in small animals, and she recently co-authored, with the help of fellow faculty member Dr. John Rush, A Color Handbook of Small Animal Emergency and Critical Care Medicine (Manson, 2007). She lives near the school's Grafton campus with, as she notes, a menagerie of pets—all rescues.
