Dr. Wijeyewickrema's laboratory researches enzymes, called proteases, which operate at the interface between a host, such as a human being and microbes that cause disease. Pathogens such as bacteria secrete proteases to breach host defenses. Yet, their primary host defense system, the immune system, also uses such enzymes to protect us from pathogens. Their research focuses on understanding the biology of enzymes from bacteria and humans, so we that can develop compounds to protect against diseases.
