Cemre Demir M.A. | ![]() |
Research:
Ms. Demir's research focus is in the area of Entrepreneurial Diversity.
The aim of this sub-discipline is to bring together the heterogeneity of entrepreneurship in the area of individual characteristics. Entrepreneurship by families, women, people with a migration background, older people, people with disabilities or career changers: all these are major sub-themes in which many research-relevant findings have already been obtained. However, these sub-topics coexist separately from each other and are treated only marginally in separate "research ghettos" compared to the Silicon Valley model companies. Entrepreneurial Diversity starts at this point in order to adjust the focus again and to generate a general theory of everyday entrepreneurship.

Tim Neuvians M.A.

Research:
Tim Neuvians' research focuses on leadership competencies in owner-managed companies during crisis and insolvency situations, particularly within the framework of self-administration under the German ESUG legislation. The aim of the study is to identify key leadership strategies, as well as structural and personnel-related factors that influence the success of restructuring and turnaround processes. Owner-managed companies face unique challenges in times of financial distress, characterized by limited financial and human resources, high emotional involvement, and complex stakeholder interactions. In particular, self-administration during insolvency — which allows companies to implement restructuring measures independently under the supervision of a court-appointed custodian — places significant responsibility on the executive management. This research analyzes which leadership competencies are essential for a successful turnaround, what challenges arise in collaboration with creditors, insolvency administrators, and courts, and to what extent proven management practices from traditional business leadership can be applied to the insolvency context. Furthermore, it investigates which leadership-related factors promote or hinder the success of the restructuring process.
