Field of research:
Medieval History

Research interests:
I am interested in Cultural antropology and Religious studies, with a focus on processes of religious conversion and the dynamics of cultural and religious exchange involved in these.

Planned research project:
This interdisciplinary project proposes to analyse the development of a local and peculiar religious identity in the region of Galicia, north-western Spain. It specifically examines the period of Christianization from Late Antiquity to the Early Middle Ages, through a historical, archaeological and anthropological perspective. The main goal of this project is to analyse peoples’ agency in “crafting” their religious beliefs and interpretations based on the process of cultural transfer and religious hybridity. I intend to identify the process that defines the selectiveness and influences the final shape that religious practices take, considering all elements involved in this process of transmission and exchange. This includes: the cultural and historical background, the characteristics of the process of Christianization, the agents promoting the diffusion of the faith and the dynamics of power that somehow influenced the religious evolution. Thus, my project takes into consideration how, during religious conversion, specifically Christianization, the elements involved in the process of hybridization, Christianity and other beliefs and practices, are in and of themselves non-static notions. There were several forms of paganism as well as Christianity and the fusion between them was a fluid process.
The aim of this research is to contribute to the creation of a method of identifying hybridity in sources and practices that can be used in other historical and cultural realities. Furthermore, it aims to shed light on the complex dynamics of cultural interaction and exchange that pervades the history of humanity.

Field of research:
Prehistoric Archeology

Research interests:
My research interests include human evolution, prehistoric technology and human environmental interactions. I have focused my attention on the recurrent Pleistocene migrations/expansions events of our species (from and back to Africa), the cultural know-how developed over the course of this processes and the subsistence strategies used by human populations to coup with extreme environments, such as the Saharo-Arabian arid belt.

Planned research project:
“How did Human Behaviour change During the Terminal Pleistocene and Early Holocene in South Arabia?”
The shift from hunting and gathering to a production-based subsistence practices represents a significant milestone in the development of our species; why chase the food when we can make the food come to us?
The longstanding and fruitful research traditions throughout the Fertile Crescent and much of North Africa have illuminated some aspects of the complex mechanisms driving processes of Neolithization, informing us that allopatric cultural progressions produced different behavioural responses within separate core areas of the Southwest Asia. Yet, little is known of how this process was manifest in the Arabian Peninsula.
The proposed research will explore human response to fluctuating environmental conditions during the Late Pleistocene and Early Holocene in the southern Arabian Peninsula, between 30.000 and 8.000 years  before present. Did the Neolithic revolution affect the developmental trajectories of archaeological cultures in this region, through either diffusion or migration? Can we identify overlapping cultural features between the Near Eastern archaeological record and that of southern Arabia, which might signify some degree of cultural contact, or perhaps even demographic origins? If so, when did this influx of new cultural features occur?

Research interests:
Foundations of Economics, i. e. Decision making under uncertainty, Complex Systems, Epistemology, Science History, History of Thought

Planned research project:
People make decisions under uncertainty every day, thus in order to make prudent decisions they turn for guidance to economics. The core of formal economics is the evaluation of uncertain prospects, where there is a paradigm change well underway. The standard line of research applies expected utility theory (EUT) to decision problems under uncertainty, whose axiomatic foundation rendered it theoretically sound, but consistent empirical violations of EUT have spurred further research and propelled the advent of behavioural economics theories (such as prospect theory, regret theory or salience theory) that try to reconcile the behavioural inconsistencies such as probability weighting or loss aversion with EUT. However, despite of immense efforts, there is no commonly accepted rational explanation of observed behaviour in decision making under uncertainty to this day. As a result, the economics community has labelled violations of the prevailing decision theory -- such as probability weighting or loss aversion -- as ‘irrational biases’ and there is a tendency to proceed to accumulate the stamp collection of such biases from the ‘wilderness of bounded rationality’. My project, The Time Resolution of the Probability Weighting Puzzle, counteracts this tendency by using a temporal optimisation scheme to identify optimal behaviour over time in repeated gambles. In my project I expand the capabilities of the newly developed research paradigm of Ergodicity Economics to repeated uncertain gambles, i.e. when there is some ignorance about the true parameters that define the gamble.

Planned research project:
“Matters of Sleep - sleep devices in the everyday life of Norwegian hospital staff”
The study aims to further the understanding of the usage of devices for sleep enhancement under extreme work conditions and seasonal variations of light/dark exposure and its implications for hospital staff and other shift workers applying ethnographic methods.
Hospital staff belongs to a high-risk group suffering from sleep deprivation and sleep disorders while at the same time its work environment demands a high level of concentration, rapid decision-making, and empathy. Nurses and MDs working night shifts above the Arctic Circle are additionally challenged by extreme circadian changes during the polar night and midnight sun periods. These specific work conditions lead to the assumption that Nordic hospital staff is particularly challenged when trying to manage a healthy day-night rhythm.
What is considered optimal sleep? How are sleep devices used by this group to enable or support it?
The study, operating on the intersection of Science and Technology Studies and Health Studies, aims to advance the knowledge of how sleep devices support and/or prevent sleep and its possible indications in the development of novel approaches on how to enhance sleep under extreme work conditions and/or seasonal variations. Further knowledge on these ‘matters of sleep’ can serve as an impetus for understanding the conditions of shift workers’ distorted sleep patterns elsewhere as well as for a broader understanding of the subjective meanings of sleep for this group and its related day-to-day practices.

Research interests:
I am interested in questions concerning the processes of collective identity formation, security narratives, and emotions in international relations, which I explore in relation to political developments in Ethiopia and the Horn of Africa. In doing so, I engage with broader theoretical and methodological debates in the field of Critical Security Studies.

Planned research project:
My DAAD PRIME project is titled ‘Rapprochement in the Horn of Africa: narratives of conflict and reconciliation in Ethiopian-Eritrean relations’. In July 2018, Ethiopia and Eritrea ended a twenty-year period of open hostility and political stalemate. The objective of this research project is to analyse narratives of conflict and reconciliation in Ethiopian-Eritrean relations since the early 1990s, to develop a better understanding of the rapprochement. In this context, I seek to explore how dominant ideas of the two states are articulated, contested and negotiated in international encounters, and the role of emotions therein.

Research interests:
Theories of imagination and conceivability; theory of cognition, especially in mathematics.

Planned research project:
"Conceiving, Imagining and Fingere as Philosophical Method in Early Modern Philosophy: Descartes and Leibniz as Case Studies."
The aim of the project is to enquire into the nature and epistemic role of imagination-based reasoning as a philosophical method during the early modern period. The imagination provides knowledge of possible situations. A possible situation refers to configurations of objects and properties which are not directly experienced by an epistemic subject, but of which she can entertain a mental representation. Imagination-based reasoning is essentially involved both in epistemic and practical reasoning, for the representation of how things could be is a mental process rational subjects naturally appeal to in order to test and revise beliefs; make decisions; and prove theories through counterfactual reasoning. If this is true, the faculty of imagination is involved in a wide range of human practices philosophers consider distinctive of human rationality, and yet this claim seems to stay in tension with early modern rationalist epistemology, according to which knowledge rests on the intellect only.
The nature of imagination-based reasoning is enquired from a particular point of view: a confrontation between two philosophers of the early modern period, Descartes and Leibniz, on issues at the intersection of mathematics, geometry, and metaphysics. The question of the epistemic role of the imagination – and especially of the role played by cognitive states such as conceiving, imagining, and feigning/pretending (fingere) in geometrical and mathematical discoveries – engages both philosophers and profoundly influences their metaphysics and epistemology.

Field of research:

Research interests:
I am interested in how human ways of thinking, learning and decision making develop during childhood and how these differ from the ways our closest relatives - chimpanzees - think, learn and make decisions. This allows us to draw inferences about human-unique strategies, skills and motivations, which may have played an important role in our evolution.

Planned research project:
“Ontogenetic and Phylogenetic Roots of Strategic Help-Seeking”
In this project, I study the development of strategic help-seeking from a comparative and a developmental perspective. By comparing the behavior of children and chimpanzees it may be possible to isolate human unique aspects of strategic help-seeking and to theorize about the evolutionary origins of different help-seeking strategies from the time when humans and chimpanzees shared a common ancestor. In addition, studying children of different age groups contributes to our understanding of the ontogenetic development of help-seeking strategies.

Research interests:

Planned research project:
Combining a literary and a historical perspective, the project focusses on the cultures of knowledge in the early imperial Rome (27 BC–138AD) and analyses literary strategies of memorization through anecdotes in historiographical and biographical texts. With a focus on one of the most productive periods of ancient anecdote writing, it analyzes the literary form and epistemic value of anecdotes. Comparing historiography to ancient medicine (case studies), the project intends to show that anecdotal historiography serves as a paradigmatic form of producing knowledge for it consists in guess work, grouping elements with similarities, and diagnosing signs and symptoms. In the steps of New Historicism, it follows a twofold systematic methodology and works with narratological and epistemological tools of analysis. As a point of departure, the project looks at the tension of immanence and transfer of meaning that either confirms or breaks the larger historical narrative. Thus, the project analyses, in a comparative perspective, how the narrative structure and the epistemic context (especially the framing) contribute to the creation of meaning and transfer of knowledge. To this end, the project (i) describes the emergences of anecdotal writing from Roman education and the sociocultural context (epistemic paradigms), (ii) analyses the narrative (markers of orality) and rhetorical (tropes) tools used in the corpus to create knowledge and transferability, and (iii) determines semiotic elements of a poetics of anecdotal history.

Planned research project:
Restoring connectivity for an endangered marsupial in a fragmented, urban Australian landscape Habitat fragmentation negatively impacts biodiversity. Restoring functional connectivity in fragmented landscapes through the establishment of corridors is vital for movement, gene flow and survival of species. Accurate identification of functional corridors usually depends on estimates of landscape resistance to dispersal movement, but collecting sufficient dispersal data is challenging. Although expert knowledge is often used, it is increasingly recognized that empirical data may be more accurate. However, how well different types of data perform to infer connectivity remain unclear, and the functionality of corridors is rarely validated. This study proposes to combine occurrence data with fine-scale movement data to estimate habitat suitability and derive landscape resistance for the squirrel glider in a highly fragmented and urban Australian landscape. The estimated resistance surface will be mapped to identify biological corridors to reconnect disjunct populations of the species across the study area. Subsequently, the corridor will be tested with genetic data.

Planned research project:
Tidal wetlands (i.e. marshes and mangroves) and other vegetated coastal ecosystems have recently been increasingly recognized as powerful carbon (C) sinks, mitigating climate change through the long-term removal of atmospheric CO2. Climatic warming can reduce the capacity of ecosystems to sequester C by stimulating microbial decomposition processes. The objective of my PRIME project is to conduct the first evaluation of the temperature sensitivity of tidal-wetland C stocks in situ by studying the effects of rising temperature on microbial activity and community structure in relation to soil depth.

"Understanding the root causes of human-wildlife conflicts for improving biodiversity conservation in protected areas."
Biodiversity conservation is receiving increasing attention, e.g. in the form of an increase in numbers and coverage of protected areas (PAs). Furthermore, many countries have signed the Convention on Biological Diversity to promote sustainable community conservation, recognizing the rights of people and addressing poverty alleviation. Despite these efforts, habitat fragmentation, overexploitation (e.g. poaching), invasive species and climate change continue to accelerate species extinctions. PA’s objectives are increasingly in conflict with local people’s activities, and thus create a negative attitude towards conservation in general and certain species. These ‘conflicts’ often appear in the form of human-human (armed conflict between rangers vs. poachers) or human-wildlife conflicts (herders vs. large carnivores). Many conservation projects follow a top-down approach, seeking to change human behavior by enforcement of laws to reduce poaching or by adopting schemes to offset damage on people’s property, but these rules are often ineffective and rather escalate conflicts. Unfortunately, there has only been scant empirical evidence for underlying assumptions of conflicts, especially in regard to socioeconomic-ecological contexts. It is important to understand the key factors changing decision-makers’ compliance on rules within social constructs (attitude, subjective norms and perceptions). In this project, we apply the theory of planned behavior offered by social-psychological science by integration with individual-based modelling (a bottom-up approach) from the ecological sciences which provides an opportunity to the understanding of individual behavior in conservation. This work has been developed to identify the root causes and mechanisms of conservation conflicts which is essential to find better mitigation pathways for conflicts and transform biodiversity conflict outcomes in PA systems.
This project will also apply meta-population models (e.g. Bayesian N-mixture model) to measure population stability (population trajectories) of large terrestrial ungulates in relation to overexploitation (i.e. poaching) over time. Ultimately, we will assess the role of protected areas in protecting megafauna in South-West Asia.

Planned research project:
„DEVELOPMENT OF 19F NMR AS AN IN SITU CHARACTERIZATION TOOL FOR ALL-SOLID-STATE BATTERIES BASED ON FLUORIDE ION SHUTTLE CONCEPT“
Fluoride ion batteries (FIB) are studied as an alternative to Li-ion batteries. It is a more sustainable and safer battery concept, as it uses globally available fluoride ions (Fˉ) and does not require a liquid electrolyte.
In this project I will do pioneer work to establish 19F solid-state NMR as a key structural characterization method for FIB. The structural origin for low specific capacities, the reasons behind their poor cyclability and the mechanisms underlying the reversible attachment of F- during cell operation will be addressed.
The outcome of this study will be the benchmark for in situ characterization in the expanding field of FIB and will contribute considerably to the understanding of this battery technology and the development of all-solid-state batteries.

"Retirement Products: Innovative Contract Design and Risk Management"
Demographic change and the current long-lasting low interest rate environment pose a severe threat to retirement systems around the world. In most developed countries, the question of how to still provide satisfactory retirement income for current and future generations will be one of the central challenges in the 21st century. Germany's life insurance and pension fund sector is especially struggling as contracts with high and long-term return guarantees remain in the company's balance sheets. The aim of this project is to better understand and manage the risks of insurance contract portfolios. We suggest on how to reduce the portfolio risk by appropriate hedging strategies and/or an innovative life and pension contract design.

“Modelling Uncertainty in Deep Learning for Medical Applications”
Deep Learning has emerged as a leading technology for accomplishing many challenging tasks showing outstanding performance in a broad range of applications in computer vision and medical applications. Despite its success and merit in recent state-of-the-art methods, DL tools still lack in robustness hindering its adoption in medical applications. Modeling uncertainty, through Bayesian Inference and Monte-Carlo dropout, has been successfully introduced to computer vision for better understanding the underlying deep learning models. In this proposal, we investigate modeling the uncertainty for medical applications given the well-known challenges in medical image analysis, namely severe class-imbalance, few amounts of labeled data, domain shift, and noisy annotations.

"Data-driven feedback control of a turbulent flow around a D-shaped body for drag reduction"
Turbulent flows over bluff bodies are inherent to numerous engineering applications where aerodynamic forces and mixing play an important role, spanning industries such as ground and marine transportation, aeronautic, energy, chemical and pharmaceutical. I am investigating the turbulent flow over a generic bluff body (a D-shaped body) to elucidate the physical mechanisms that allow drag reduction via direct wake manipulation using unsteady Coanda blowing. Experimental data is being used to build an interpretable model that captures the dominating spatio-temporal features of the flow and at the same time is simple enough to allow online control. Subsequently, a model-based feedback controller will be developed using only body-mounted sensors and actuators and will be implemented in wind tunnel experiments. Besides the direct step toward active drag reduction of cars, trucks, trains and ships, the advances in closed-loop turbulence control will have profound implications as an eventual enabler of lift increase of airplanes and wind turbines, mixing enhancement in heat exchangers, optimization of chemical processes, and cleaner combustion.
