About the Lab

The Sanger Research Lab was launched to accelerate the creation and dissemination of cutting-edge leadership research. To support the development of leadership scholarship, the lab provides an inclusive community for scholars from across the university (representing fields from medicine, psychology, marketing, management, and more) to share and receive feedback on early-stage research. The lab also offers research support, such as research assistantship and research fellowships, to faculty and PhD students.

To support the dissemination of leadership research, our faculty work closely with the Sanger team to ensure all of our programs, communities, and events are building on the best and most recent evidence-basis within scholarly communities. Sanger also works with our faculty to disseminate research ideas on social media, in blogs, and within speaker events (such as the Leadership Dialogues series).

Members of our lab love to connect with others and do so in many ways, including welcoming in new PhD students, postdocs, and faculty from across campus, sponsoring speaker events and conferences, and connecting our faculty with students, alumni, and companies (for research, workshops, coaching, etc). If you’d like to get involved, please don’t hesitate to reach out!

Image Risks Can Hold People Back from Stepping into Leadership Positions:

Although many organizations value leadership across levels, individuals are reluctant to step up and lead. We explore across four studies how anticipated image risk (i.e., an individual’s belief that the act of leading might harm their image with others) and lay beliefs about leadership ability (i.e., that this ability is fixed versus malleable) may diminish an individual’s endorsement of a leader identity and thus their leadership emergence.

Meetings and Individual Work During the Workday: Examining Their Interdependent Impact on Knowledge Workers’ Energy

Leaders must learn to manage their energy and that of their people. Meetings often take up a big chunk of one’s workday. In this research, we demonstrate how meetings (esp. high pressure meetings) crowd out energy management activities which keep us from feeling depleted. By alternating meetings with individual work time, individuals can feel more energized at the end of the workday.

Examples of Current Research Collaborations

Paths to Leadership.

Many in our laboratory are interested in who steps into, and who is granted, leadership positions. Ongoing research projects exist about who identifies as a leader, and how companies can encourage more people (including from diverse backgrounds) to self-identify as leaders and step into leadership positions. Research is also ongoing about who is granted leadership roles in organizations and how best to identify leaders in ways that are least biased.

Faculty and PhD students: Susan Ashford, Charlie Case, Julia Lee-Cunningham

Leader Communication.

There are also ongoing projects about how a leader’s communication can optimize their team’s organizational performance. This ranges from the words leaders use in mass communications to the dynamics of information flow within team meetings. Being able to inspire hearts and minds in order to steer a team and organization to goal achievement is a key skill!

Faculty and PhD students: Derek Harmon, Julia Lee-Cunningham, Elizabeth Trinh

How Leaders Navigate Emotions at Work.

Many lab members are also interested in how leaders navigate emotions at work, including how leaders recognize and respond to the emotions of others. Seeing the full human being of others is critical in order to help support and mobilize groups toward goal achievement.

Faculty and PhD students: Christina Bradley, Lindy Greer, Jeffrey Sanchez-Burks, Derek Harmon, Elizabeth Trinh

Leading Diverse and Inclusive Teams and Organizations.

Leading diverse and inclusive teams and organizations is a critical skill set. Our lab has several active projects on this topic, including one on the well-meaning steps leaders can take toward inclusion—which at times can backfire, as well as one on the criticality of diversity in powerful teams like boards.
