Environmental Transmission of Pathogens and Implications on Infectious Disease Surveillance
(2022)Indirect disease transmission occurs when pathogens are shed into the environment during transmission from infected to susceptible people. This environmentally-mediated transmission is characteristic of respiratory, gastrointestinal, and nosocomial pathogens, and can be conceptualized by the commonly described “F-diagram”. The “F-diagram” is a model of the role environmental compartments (food, fluids, fingers, fomites, fields, and flies) ...Habilitation Thesis -
Environmental Chemistry of Biomolecules
(2022)This habilitation thesis entitled “Environmental Chemistry of Biomolecules” focusses on determining chemical information to evaluate water quality and to protect human health and ecosystem functioning. Such knowledge is crucial for public authorities to manage water resources especially as we are facing growing inputs of bioactive chemicals with adverse environmental effects. My work is rooted in environmental and analytical chemistry of ...Habilitation Thesis -
Facts and values: Decision analysis for complex public environmental decision problems
(2022)Decision analysis can support complex public environmental problems in a consistent, structured way. My field of research is prescriptive decision theory, focusing on multi-criteria decision analysis (MCDA), specifically multi-attribute value theory and utility theory. After an introduction, I review MCDA for environmental decision-making from the view of operational research (OR). MCDA is widely used in practice, but uncertainty and ...Habilitation Thesis -
Strategic use of the bioactive properties of n–3 fatty acids and plant secondary compounds in the diet of ruminant farm animals
(2021)Ruminant production systems are increasingly critically discussed for reasons that can be summarized as environmental, ethical, animal welfare, and human health concerns. Looking at the development during the past decades and the predictions for the ones to come, ruminant-derived food production will however still rather increase than decrease. The impressively enhanced production efficiency via breeding strategies in ruminants contributes ...Habilitation Thesis -
Process and Configurational Perspectives in Corporate Sustainability
(2020)The collection of manuscripts submitted as habilitation in management science outlines a research agenda towards more process and configurational research in corporate sustainability. The habilitation thesis is structured in three sections. Section 1 contains five empirical studies that each offer a unique process and configurational perspective on issues of managerial relevance in corporate sustainability. These studies draw on various ...Habilitation Thesis -

Architecture in the Public Eye: Buildings, Words, and Images in Britain, 1800-1950
(2021)‘Architecture in the Public Eye’ examines the roles that words and images have played in the representation of cities and their buildings in a number of British illustrated media between the early 1800s and the mid 1900s. The research presented examines, on the one hand, how architecture was presented, explained and situated for the lay reader in newspapers and textbooks and, on the other, how the emerging genre of the architectural ...Habilitation Thesis -
Sustainability Transitions: Research agenda, technological innovation systems and organizations
(2020)We are confronted with grand sustainability challenges such as climate change, air pollution, deforestation, loss of biodiversity and many more. To address these challenges, we need fundamental changes in how we produce and consume things. We need to transform technologies, business models, industries, policies, lifestyles and consumption patterns. Such kinds of changes are not only needed in some places but at a global scale and in many ...Habilitation Thesis -

Collaborative Organizing for Innovation and Entrepreneurship
(2020)With the rise of the knowledge economy and an increasing demand for innovation, collaboration is gaining prominence as an organizing principle. This habilitation thesis centers on the question how individuals collaborate to innovate and to explore entrepreneurial opportunities. My coauthors and I draw on both organizational and psychological theories to study this important phenomenon in three empirical contexts: open-source software ...Habilitation Thesis -

Collective Grounds
(2019)This Habilitation thesis focuses on the relation between cities and urban housing estates, understood as ensembles of two or more, medium- to high-density, primarily residential buildings, conceived at the same time and with a level of common administration. The earliest housing estates were conceived islands of hygiene and propriety, kept apart from the decaying physical and moral urban fabric around them. This initial understanding ...Habilitation Thesis -
A solid-state NMR tool box for the investigation of ATP-fueled protein engines
(2019)Motor proteins are involved in a variety of cellular processes. Their main purpose is to convert the chemical energy released during adenosine triphosphate (ATP) hydrolysis into mechanical work. In this work, solid-state Nuclear Magnetic Resonance (NMR) approaches are discussed allowing to study structures, conformational events and dynamic features of motor proteins during a variety of enzymatic reactions. Solid-state NMR benefits from ...Habilitation Thesis -
