Dr. Bullock’s research focuses on how message design can reduce barriers to information processing, and how effective information processing evoked through message design can facilitate persuasion. She explores these ideas in risk, health, and science communication contexts. In addition to her research, Dr. Bullock is also a communication practitioner, with previous experience working in public relations and advertising for agencies in Washington, D.C., and as a consultant on the Department of Health and Human Services’ “We Can Do This” COVID-19 vaccine campaign.
