PhD student in Scientific Computing focusing on positivity preserving and low-rank tensor approximation of fusion

Published: 2022-05-20

Uppsala University is a comprehensive research-intensive university with a strong international standing. Our ultimate goal is to conduct education and research of the highest quality and relevance to make a long-term difference in society. Our most important assets are all the individuals whose curiosity and dedication make Uppsala University one of Sweden’s most exciting workplaces. Uppsala University has over 54,000 students, more than 7,500 employees and a turnover of around SEK 8 billion.

The Department of Information Technology has a leading position in research and all levels of higher education. Today the department has 300 employees, including 120 academic staff and 110 full-time PhD students. The Department comprises research and education in a spectrum of areas within Computer Science, Information Technology and Scientific Computing. More than 4000 students take one or several courses offered by the Department each year.

The position is hosted by the Division of Scientific Computing within the Department of Information Technology. As one of the world’s largest focused research environments in Scientific Computing the research and education has a unique breadth, with large activities in classical scientific computing areas such as mathematical modeling, development and analysis of algorithms, scientific software development and high-performance computing. The division is currently in an expansive phase in new emerging areas such as cloud and fog computing, data science, and artificial intelligence, where it plays key roles in several new strategic initiatives at the University.

Our PhD programs in scientific computing has resulted in over 80 completed PhD theses over the years. Several PhD alumni in Scientific Computing from Uppsala University are successful practitioners in the field, in industry as well as in academia.

Project description
The goal of this project is to develop a structure-preserving low-rank tensor discretization for high-dimensional partial differential equations modeling fusion processes. The mathematical model that we mainly consider in this project is the Vlasov-Maxwell system. The specific goal of the project is the construction, analysis, and implementation of numerical approximations of the Vlasov-Maxwell system that preserve the basic physical properties such as the positivity of the plasma distribution function. The project will be carried out in cooperation with the Ruhr University Bochum, Germany, and the candidate is expected to visit Bochum several times during the course of the project.

Previous knowledge of numerical methods for partial differential equations and excellent programming skills are required.

Duties
The duties of a PhD student are primarily directed at their own research education, which lasts four years. The work may also involve, to a limited extent (maximum 20%) other departmental duties, such as teaching undergraduate courses and administrative tasks – in which case the position may be extended to a maximum of five years. 

Requirements
A PhD position at the Division requires a Master of Science or equivalent in a field that is relevant to the topic of the PhD thesis, good communication skills and excellent study results, as well as sufficient proficiency in oral and written English. Knowledge and experience in programming (preferably C and C++), analysis of initial-boundary value problems and finite element methods are of additional importance.

Additional qualifications
Basic knowledge of fluid mechanics and plasma physics is considered to be an advantage.

Rules governing PhD students are set out in the Higher Education Ordinance chapter 5, §§ 1-7 and in Uppsala University's rules and guidelines .

About the employment
The employment is a temporary position according to the Higher Education Ordinance chapter 5 § 7. Scope of employment 100 %. Starting date 2022-09-01oras agreed. Placement: Uppsala.
