Theses by Giacomo Molinari (edited by Arthur Van Camp)
On October 21st, 2024, I defended my PhD thesis: “Deference principles for Imprecise Probabilities”.
I worked on this thesis over the last four years, under the supervision of Jason Konek and Catrin Campbell–Moore.
My research was part of the ERC-funded project “Epistemic Utility for Imprecise Probability” hosted by the Department of Philosophy at the University of Bristol.
This meant I had the fortune to work alongside Arthur Van Camp and Kevin Blackwell, who were postdocs on the project.
I also benefited greatly from a research visit at MIT, hosted by Kevin Dorst.
My PhD examiners were Jim Joyce and Richard Pettigrew.

Theses by Loïc Adam (edited by Arthur Van Camp)
I defended my PhD thesis “Apprentissage de préférences sous incertitude sévère” (“Learning Preferences under Severe Uncertainty” in English) the 23rd October 2023.
I worked for 3 years at the laboratory Heudiasyc (Heuristic and Diagnostic of Complex Systems, UMR-CNRS 7253) of the Université de Technologie de Compiègne, France, under the supervision of Sébastien Destercke.
My PhD committee included Hélène Fargier, Wassila Ouerdane, Nadjet Bourdache, prof. Frédéric Koriche, prof. Sylvain Lagrue and Olivier Spanjaard.
Although my PhD manuscript is in French, my work can be found in English: Possibilistic preference elicitation by minimax regret and Handling inconsistency in (numerical) preferences using possibility theory.

Theses by Arianna Casanova Flores (edited by H. Diego Estrada-Lugo & Alexander Erreygers)
In July 2023, I successfully defended my PhD thesis entitled “Rationality and desirability - A foundational study”.
This work reflects five years of research at the Dalle Molle Institute for Artificial Intelligence USI-SUPSI (IDSIA) in Lugano, under the supervision of Prof. Marco Zaffalon and Prof. Luca Maria Gambardella.
Alongside Prof. Zaffalon and Prof. Gambardella, my committee included Prof. Fabio Crestani, Prof. Ernst C. Wit, Prof. Matthias C.M. Troffaes and Dr. Nic Wilson.

Theses by Dominik Hose (edited by Henna Bains)
On May 20th in 2022, I successfully defended my PhD thesis [1] entitled “Possibilistic Reasoning with Imprecise Probabilities: Statistical Inference and Dynamic Filtering”. This dissertation is the result of five wonderful years at the Institute of Engineering and Computational Mechanics at the University of Stuttgart under the enthusiastic supervision of my “Doktorvater” Michael Hanss. Apart from him, my committee was also composed of Scott Ferson and Ryan Martin—but we will get to that.

Theses by Tathagata Basu (edited by Henna Bains)
After three years of research and extensive brainstorming with my supervisors; Jochen Einbeck and Matthias Troffaes, I finally defended my thesis on 15th December 2020. The thesis, entitled “High dimensional statistical modelling under limited information” was examined by Dr Hailiang Du and Dr Erik Quaghebeur in the presence of Dr Ostap Hryniv.

Theses by Jasper De Bock
On 13 May 2015, after four years of intensive research under the enthousiastic supervision of Gert de Cooman, I succesfully defended my PhD Thesis, entitled “Credal Networks under Epistemic Irrelevance: Theory and Algorithms”. The jury was composed of Fabio Cozman, Enrique Miranda, Serafín Moral, Joris Walraevens, Dirk Aeyels, Dries Benoit, Jan Van Campenhout and Rik Van de Walle. My dissertation presents a detailed study of credal networks under epistemic irrelevance, which are probabilistic graphical models that can compactly and intuitively represent the uncertainty that is associated with the key variables in some domain, and which can then be used to answer various domain-specific queries (compute inferences) that are of interest to the user. They share many of the nice features of Pearl’s celebrated Bayesian networks, but have the added advantage that they can represent uncertainty in a more flexible and realistic way.

Theses by Ignacio Montes
This thesis, supervised by Enrique Miranda and Susana Montes, was defended on May 16th. The jury was composed of Susana Díaz, Serafín Moral and Bernard De Baets. This thesis deals with the problem of comparing alternatives defined under some lack of information, that is considered to be either uncertainty, imprecision or both together.

Theses by Andrea Wiencierz
My PhD thesis deals with the statistical problem of analyzing the relationship between a response variable and one or more explanatory variables when these quantities are only imprecisely observed. Regression methods are some of the most popular and commonly employed methods of statistical data analysis. Like most statistical tools, regression methods are usually based on the assumption that the analyzed data are precise and correct observations of the variables of interest. In statistical practice, however, often only incomplete or uncertain information about the data values is available.

Theses by Dennis D. Mauá
My PhD thesis is about connecting three hard computational problems that arise in tasks involving graph-based probabilistic reasoning, namely, the problems of maximum a posteriori (MAP) inference in Bayesian networks, planning with influence diagrams, and belief updating in credal networks under strong independence (or simply strong credal networks). Roughly speaking, in the MAP inference problem we seek the most probable explanation of a complex phenomena represented as a Bayesian network, a graph-based description of a multivariate joint probability distribution where nodes are identified with random variables and local conditional probability distributions.
