Doctoral student in Explainable Machine Learning for Neuromorphic Computing

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. Entry requirements and selection For admission to doctoral studies, applicants are required to meet both the general entry requirements (https://www.oru.se/english/study/doctoral-education/how-to-become-a-doctoral-student/) and specific entry requirements. In addition, applicants must be considered in other respects to have the ability required to benefit from the programme. For a full account of the entry requirements, refer to the admissions regulations (https://www.oru.se/globalassets/oru-en/education/research-education/application-and-admission/antagningsordning-for-utbildning-pa-forskarniva-vid-orebro-universitet_en.pdf) as well as to annex 2 to the general syllabus for mathematics (https://www.oru.se/globalassets/oru-en/education/research-education/general-syllabi/allman-studieplan-matematik_beslut_2024-06-13_en.pdf).

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. Supervision: The doctoral student will be supervised by Leo Yeung (principal supervisor) and Felicia Fredriksson (assistant supervisor).
