Luleå University of Technology is growing rapidly with world-leading expertise in several research areas. We shape the future through innovative education and groundbreaking research results, and based on the Arctic region, we create global social benefits. Our scientific and artistic research and education are conducted in close collaboration with international, national and regional companies, public actors and leading universities. Luleå University of Technology has a total turnover of almost SEK 2.1 billion per year. We are currently 1,900 employees and have 18,700 students. In the coming years, billions of kronor will be invested in Norrbotten and Västerbotten in major projects aimed at a more sustainable society nationally as well as globally. Luleå University of Technology is involved in several of these highly topical research projects and the social transformation that follows. We have a wide range of programs to match the skills that are in demand. We hope that you want to help us build the sustainable companies and communities of the future. Luleå University of Technology is implementing an initiative to strengthen research and education in cybersecurity by establishing a new research group in the field. The initiative is directly related to the university's successful ICT environment with several strong research groups that offer good synergy opportunities. We therefore see a focus on research and development of methods to protect different types of systems connected to the internet as important. These systems range from small sensors to large-scale control systems for society's energy supply, and the research covers everything from deep research at the methodological level, e.g. algorithm development, to applied research in collaboration with other groups. The Cyber Security subject at the Department of Computer Science, Electrical and Space Engineering, Luleå University of Technology is now looking for a PhD student to contribute to our growing activities. Subject description Cybersecurity focuses on technical security aspects and protection of systems connected to the internet and includes protection of software, data and hardware. Project description This PhD project focuses on predicting cybersecurity threats using eXplainable AI. You will work with colleagues in our cybersecurity team at Luleå University of Technology and also our partner in Cybercampus Sweden, RISE. We will use methods and technologies such as expert systems, evolutionary algorithms, semi-supervised learning and eXplainable AI. Work tasks A PhD position involves both theoretical and practical work. As a PhD student, you will be trained in scientific work in the form of publishing scientific articles in journals and at national and international conferences. You will also take compulsory and optional doctoral courses. In addition, you may have the opportunity to try out the role of teacher. As a researcher, you will work as a neutral party in many contexts, providing a great opportunity to learn how to run challenging development projects. Qualifications We are looking for analytical and motivated colleagues who can carry out advanced research both independently and in collaboration with others in our research group. You should have a Master's degree in Computer Engineering or equivalent. In addition, the applicant should have expertise in expert systems, evolutionary algorithms, semi-supervised learning and eXplainable AI.
