  • Research Interests

    Dr. Cashdollar has provided management of the Core Laboratories at the Versiti Blood Research Institute since 2000. The Research Core Laboratories provide specialized research services to investigators, along with the latest technology in equipment and software. The Core facilities are staffed by specialists and technologists with a high level of expertise in the various technologies provided by the Core labs.

    Prior to assuming this role Dr. Cashdollar’s career focused on research in virology. He was involved in the first attempts to clone genes from viruses of the reovirus family and later studied the interaction of viruses and the immune system.

    Throughout his career Dr. Cashdollar has maintained an interest in education. He has taught medical and graduate students at the Medical College of Wisconsin for 35 years.  He was recently recognized for his role in establishing the Summer Program for Undergraduate Research (SPUR) at the Medical College of Wisconsin.
