Josh Greenberg, Ph.D., is an Associate Professor and Director of the School of Journalism and Communication. His current research explores media coverage of outbreaks and infectious disease risks; the risk communication activities and strategies of key public health actors; and the impact of technology change on public health communication. He is currently leading a study funded by the Canadian Immunization Research Network on media narratives of infectious disease and the thorny communication problems posed by vaccine hesitancy. 

Professor Greenberg sits on the editorial board of the Journal of Professional Communication. He is an advisory board member of Evidence for Democracy and The Warning Project, and is on the organizing committee of the Canadian Health Adaptations Innovations Mobilization Centre. He has worked as a consultant to both government and public sector organizations and is a regular media commentator in his areas of expertise.
