  • ​​​Academic Credentials:

    Doctor of Philosophy in Microbiology and Immunology from Louisiana State University Health Sciences Center​​​​
    Bachelor of Arts in Biology-Chemistry from Manchester University​

    ​​Dr. Charvat received ​his Bachelor's de​gree from Manchester University where he was enthralled by microorganisms and how infectious diseases have shaped human history.​​ Intrigued by this tiny world only visible through a microscope, Dr. Charvat pursued a graduate degree in microbiology and immunology​ studying equine herpes virus and the molecular basis of persistent infection.​ His passion for microbiology led to a postdoctoral fellowship at the Indiana University School of Medicine, where he examined mechanisms of drug activity and resistance in the parasite Toxoplasma gondii. ​​Dr. Charvat's fascination with microbes and antibiotic resistance has continued, which have become the focus of many of his research projects here at the University of Findlay.

    Students interested in ​research concerning microbiology, antibiotic resistance, and drug discovery should contact Dr. Charvat directly.
