Institute for Mixed Leadership (IML)

Living diversity. Leading with innovation.

Promoting equality, conveying diversity as a strength, and supporting the change of company culture

The Institute for Mixed Leadership (IML) bundles the already broad range of research of the Frankfurt UAS on the topics of innovative leadership, change of management culture, and diversity as a success factor for businesses, and develops them further based on the needs of the professional world. The goal is to use practical research to help increase the share of women in management positions in companies, enhance their acceptance, develop men’s acceptance of diverse management teams, and recognize the benefits of mixed gender and diverse management teams.

Director of the Institute is the attorney Prof. Dr. Andrea Ruppert. Other members of the directorate are Prof. Dr. Regine Graml, Prof. Dr. Veronika Kneip, and Prof. Dr. Martina Voigt . All four academics have been researchers and teachers for many years at the faculty of Business and Law of the Frankfurt UAS on gender issues in the context of management and leadership; their work includes the use of power, role stereotypes, career-oriented networks, diversity in management, compatibility of career and family, reflection of role models, and gender skills.

In addition to research, the IML will set the focus on equality, equal opportunity, and awareness in the area of mixed leadership in its events and consulting programs. The goal is also to expose and deconstruct the structural barriers and existing stereotypical attributions that affect both men and women.  

The Institute for Mixed Leadership will operate an executive academy called the Academy of Mixed Leadership to shape the change of management culture through continuing education modules for executives and businesses and to raise awareness for the increasingly economic need for diversity. Men and women in particular should be empowered and strengthened to accept and perform management responsibilities. For more information, see the Academy of Mixed Leadership (German only).

The idea arose due to the participation of the City of Frankfurt am Main in the European Equality Charter. With great commitment, the parties involved in the process developed an action plan for equality and gave birth to the idea of founding an Academy of Mixed Leadership to increase the share of women in management positions. The Frankfurt UAS is now implementing this idea with the support of the City of Frankfurt am Main.
