Dr. Peabody was trained at Stanford University in the laboratory of Paul Berg (Nobel Prize, 1980) and has been associated with UNM since 1984. For a number of years he studied RNA viruses of bacteria as model systems to understand gene regulation, but in recent years has focused on adapting the virus-like particles of these bacteriophages as platforms for vaccine discovery and delivery.
