Alicia Olivier    DVM, PhD, DACVP

Dr. Olivier holds a Doctor of Veterinary Medicine degree from Mississippi State University, a Ph.D. degree in veterinary pathology from Iowa State University and is a boarded anatomic pathologist. She is currently an assistant professor in the Department of Pathobiology and Population Medicine at MSU-CVM and serves as the faculty director of the histology laboratory. She works closely with veterinarians to diagnose disease is a wide variety of species through necropsy and histopathologic evaluation. This evaluation often necessitates utilization of further testing or special stains to reach the diagnosis.

Charlie Johnson    DVM, PhD, DACVP (anatomic pathology)

Dr. Johnson obtained his veterinary degree from the University of Minnesota in 2003. Following graduation, he was in a mixed animal practice then returned to school at Iowa State University to obtain a PhD in veterinary pathology and complete an anatomic pathology residency.
