The examination committee: Dr Kenneth Jørgensen, Professor, Malmo University, Sweden (external) and Dr David Dawson, Reader, University of Gloucestershire, UK (internal).

Supervised by: Romeo V. Turcan

Demet explored how Authentic Leadership manifests within executive boards of Swiss public-sector hospitals. Constructivist Grounded Theory Methodology was adopted to dscover major concerns executive board leaders in Swiss public-sector hospitals face and how they resolve them. The research led to the emergence of Power Channeling that is " an authentic process of social impact to form reciprocal collaborations, which maximizes the engagement of executive leaders, toward the achievement of a goal". The emergent substantive theory of Power Channeling reveals new and original knowledge about Authentic Leadership mechanisms and enhances the discourse on Authentic Leadership.

Demet is a CEO at the Pflegeheim Fuhr, Zürich, Schweiz. She worked as a director of a public hospital in Switzerland, and held different leadership positions in the Swiss Leading Private Hospitals Group Hirslanden and, as CEO, in an IT company. She also holds an Advanced Postgraduate Diploma from University of Gloucestershire and BSc in Economic Science from Bern in Switzerland.

Matthias Zach

Matthias successfully defended his PhD thesis titled "Exploring the emergence and shifting of new and radical product concepts in the context of In-vitro Diagnostics industry" on June 10, 2020 at University of Gloucestershire, UK.

The examination committee: Professor Nikolaos Tzokas of Mohammad Bin Salman College of Business & Entrepreneurship, Saudi Arabia (external) and Dr Phillipa Ward of University of Gloucestershire (internal).

Supervised by: Romeo V. Turcan and Carsten Bartsch

Matthias explores how new radical product concepts emerge under uncertainty in the context of the In-vitro Diagnostics (IVD) industry. Specifically, he studies how new product concepts that build on fundamentally new technology are elaborated, defined and modified in an early development stage within a globally operating corporation. In his theory building thesis, Matthias develops a theory of Scoping to explain the emergence of new product concepts under uncertainty. This thesis sheds light on the dynamics of new, radical product development in complex market and corporate environments, contributing to our understanding of constant adaptation processes - concept shifts - during early development phases.

Matthias is an Innovation Manager, working in the medical device industry. In the past years, Matthias held various positions in the pharmaceutical and life sciences industries. His research interest is Innovation and R&D Management particularly in the context of highly regulated industries. He also holds a Master in European Business from the ESCP Europe Business School and a diploma in pharmaceutical engineering.
