Dr. Roger Ramirez-Barrios receives Zoetis Research Award
Roger Ramirez-Barrios, clinical associate professor of veterinary parasitology, has been awarded the prestigious 2023 Zoetis Research Award. This award acknowledges researchers whose innovative studies advance the scientific standing of veterinary medicine.
His recent work has focused on two parasites that pose health risks to humans and animals: Echinococcus multilocularis and Trypanosoma cruzi. He also explored Chagas disease, caused by T. cruzi, a condition personal to him because of its impact on his family.
Ramirez-Barrios emphasizes his students' role in his research. He also said he appreciates the supportive environment at the college, particularly praising the resources provided by the Collaborative Multidisciplinary Research Laboratory.
