About Laura O’Sullivan

Dr. Laura O’Sullivan graduated from the University of Pennsylvania School of Veterinary Medicine and has been practicing small animal emergency and general medicine for the past seven years. She has a long-standing interest in One Health, the concept that the health of humans, animals, and the environment is all related. Because of that interest, she returned to school to pursue a Master of Public Health at Johns Hopkins Bloomberg School of Public Health, which she completed in 2020.

Since then, she has remained in clinical practice while also maintaining an active role in research and education surrounding One Health. She enjoys educating her clients, other veterinarians, and students about the One Health concept and how to apply it to their own careers. She is particularly interested in rabies control, antimicrobial resistance and stewardship education, and zoonotic diseases and spillover events. She joined the University of Vermont in the Spring of 2021.

Community Engagement

In 2018, Dr. O’Sullivan visited Siem Reap, Cambodia, where she volunteered her services at Siem Reap Veterinary Care. That experience inspired her to pursue her MPH and give back on a larger scale. Since then, she has assisted in infectious disease and epidemiology course development for veterinary trainees in developing nations. Additionally, she has been an acting veterinarian at the Delaware Humane Association’s One Health Clinic, a clinic dedicated to providing One Health services to pets and their owners. Currently, she sits on the board of EROVAAT, an organization dedicated to eliminating rabies in Cambodia.
