This study examines U.S-based microbiologists to better understand the frequency with which they engage in public communication, how they evaluate their public communication experiences, and what’s associated with their willingness to engage in face-to-face and online communication in the future. Data from a multi-wave online survey suggests that microbiologists (N = 903) are somewhat frequent communicators who derive great value from their outreach efforts. Results indicate that microbiologists are more willing to engage in public communication activities if they have more positive attitudes about communication and if they believe they can communicate effectively. The study also found evidence that more younger microbiologists and those with higher levels of research productivity (measured in terms of respondents’ publication productivity) are more willing to partake in public engagement activities.
