Örebro University and the School of Science and Technology are looking for a doctoral student for the doctoral programme in mathematics, concluding with a doctoral degree.
Start date: Autumn semester 2026.
Project description
To invest in stocks or some other fluctuating commodity requires, in most cases, some mathematical model of risk, return (profit), or utility (some balance between risk and return). A classical model goes back to 1952 and Markowitz. Later, more advanced models go under the name Modern Portfolio Theory. Those models may be ill-posed, meaning that changes in data might result in very different investment strategies. One such example of ill-posedness is when some of the commodities are highly correlated. This project is about analyzing such ill-posed portfolio optimization and developing stable and efficient algorithms for solving them.
Supervision: The doctoral student will be supervised by Professor Mårten Gulliksson (principal supervisor), Docent Magnus Ögren and Docent Stepan Mazur (assistant supervisors).
The programme and the doctoral studentship
The doctoral programme consists of courses and an independent research project that you will present in a doctoral thesis. The programme concludes with a doctoral degree and comprises 240 credits, which corresponds to four years of full-time study.
The plan is that the doctoral student will be active with teaching duties corresponding to about 20% of the time, giving a total time of five years.
Our ambition is for your doctoral studies to be stimulating and purposeful throughout the programme until you have obtained your doctoral degree. A thorough introduction will therefore get you off to a good start and provide a solid foundation on which you can build your studies. As a doctoral student at Örebro University, you will be offered a specially tailored seminar series, covering matters ranging from doctoral programme rules and careers to support during the study period and networking.
The place on the programme is linked to a full-time doctoral studentship for the duration of the study programme, which corresponds to four years of full-time study. More information on doctoral studentships, part-time studies and part-time doctoral studentships can be found in the Regulations Handbook (https://www.oru.se/globalassets/oru-en/education/research-education/regelhandbok-for-utbildning-pa-forskarniva_en.pdf). The initial salary for a doctoral studentship is SEK 32,300 a month.

Örebro University and the School of Science and Technology are looking for one doctoral student for the doctoral programme in Computer Science, concluding with a doctoral degree. Start date: Fall 2026. The PhD student will belong to the graduate school within the Wallenberg AI, Autonomous Systems and Software Program (WASP). WASP is Sweden’s largest individual research program ever, a major national initiative for strategically motivated basic research, education and faculty recruitment. The program addresses research on artificial intelligence and autonomous systems acting in collaboration with humans, adapting to their environment through sensors, information and knowledge, and forming intelligent systems-of-systems. The vision of WASP is excellent research and competence in artificial intelligence, autonomous systems and software for the benefit of Swedish society and industry. Read more: https://wasp-sweden.org/ The graduate school within WASP is dedicated to provide the skills needed to analyze, develop, and contribute to the interdisciplinary area of artificial intelligence, autonomous systems and software. Through an ambitious program with research visits, partner universities, and visiting lecturers, the graduate school actively supports forming a strong multi-disciplinary and international professional network between PhD-students, researchers and industry. Project description The PhD student will be affiliated with the Department of Computer Science and will carry on research within the field of cybersecurity for embodied AI. While cybersecurity threats in AI are often studied in software-based environments, the physical embodiment of AI in robots and autonomous systems introduces new, largely unexplored risks and opportunities. This PhD project will investigate: How embodiment and physical configuration affect the cybersecurity posture of AI-driven systems; The role of self-awareness in security, i.e., how robots can assess their own vulnerabilities based on their embodiment and operational state; How dynamic reconfiguration can enhance resilience, e.g., redistributing sensor reliance, modifying behaviour or adjusting control strategies in response to attacks. Rather than relying solely on traditional security mechanisms, this research aims to explore how AI systems can proactively evaluate their own weak points and autonomously adapt to mitigate security risks. Supervision: The doctoral student will be supervised by Dr. Alberto Giaretta (primary) and Professor Mauro Conti (secondary).

Örebro University and the School of Science and Technology are looking for a doctoral student (PhD student) for the doctoral programme in Chemistry, concluding with a doctoral degree. Start date: Fall 2026. Project description The doctoral student will be part of the research project COAST PFAS – Coastal PFAS Transition Lab for Source Control, Substitution and Governance, a transdisciplinary initiative addressing the spread of per- and polyfluoroalkyl substances (PFAS) from urban and industrial sources to coastal environments. The project combines environmental analytical chemistry, wastewater and stormwater research, process understanding, and systems perspectives to support preventive and sustainable PFAS management. The PhD project is connected to the work package PFAS flows from land to sea, which focuses on identifying, mapping, and quantifying PFAS sources and transport pathways in urban water systems and coastal environments. The research will include targeted and non-targeted PFAS analysis in wastewater, stormwater, industrial effluents, and receiving waters. The research will also include the development of sector-specific PFAS fingerprints and mass-balance approaches. The doctoral student will work with advanced analytical methods including LC-MS/MS, combustion ion chromatography, extractable organofluorine (EOF), oxidation methods for PFAS precursors, and high-resolution mass spectrometry for suspect and non-target screening. The work also includes interpretation of large analytical datasets and integration of results into source-tracking and fate-assessment frameworks. The project is conducted in close collaboration between IVL Swedish Environmental Research Institute, Chalmers University of Technology, Örebro University, VA SYD, and Malmö City. The doctoral student will be part of an interdisciplinary and international research environment involving analytical chemistry, environmental engineering, and sustainability research. The position involves collaboration with researchers and stakeholders across academia, industry, and the public sector, and parts of the research may therefore be conducted at different research institutions and partner organizations in Sweden and internationally. The successful candidate is expected to actively participate in field sampling campaigns, laboratory work, workshops, and collaborative research activities within the COAST PFAS Transition Lab.
