Gender demographics of departmental seminar speakers reflect gender disparities of faculty hosts

Increasing access, representation, and retention of underrepresented groups is essential across academia. Invited speaker seminars are common practice in academic science departments and serve to disseminate research, establish connections and collaborations, advance faculty careers, and connect trainees to mentors outside of departmental faculty. Thus, lack of representation among seminar speakers can affect both faculty and trainee professional development. This study characterizes gender demographics of seminar speakers across science departments at an R1 institution for the years 2015–2019, using pronoun usage as a proxy for gender identity. We found that most faculty and invited speakers were male, and few were female or nonbinary. The percentage of female and nonbinary invited speakers increased from 2015–2019 along with the percentage of female and nonbinary host faculty. Overall, male faculty hosted fewer female and nonbinary speakers than their female and nonbinary faculty colleagues. This study provides evidence for a correlation between faculty identity and the scientists they host at their department and motivates further studies investigating this relationship at other R1 institutions and institution types.
