Doctoral Student in Numerical Methods for Functional Calculus KTH Royal Institute of Technology in Sweden

The Department of Mathematics at KTH Royal Institute of Technology invites applications for a full-time doctoral student position in Numerical Methods for Functional Calculus, supervised by Dr. Kristin Kirchner. This research opportunity is funded by the European Research Council (ERC) Starting Grant FunCalc4Stats and is situated at the intersection of numerical mathematics and functional analysis. The project aims to develop foundational numerical analysis techniques for functional calculus, focusing on the approximation of functions acting on operators, such as computational methods for fractional powers of differential operators. A significant aspect of the research will involve the development, implementation, and error analysis of finite element methods for these advanced mathematical problems.

The doctoral student will join a vibrant research environment within KTH's Department of Mathematics, which hosts around 55 PhD students and covers a broad spectrum of mathematical disciplines. The position includes some departmental duties, primarily teaching at the basic level, which can be conducted in English. Support for learning Swedish is available for interested candidates. The successful applicant will be part of a dynamic academic community and benefit from KTH’s commitment to equality, diversity, and attractive working conditions.

Applicants must hold a second cycle degree (such as a master's degree) or have completed at least 240 higher education credits (with at least 60 at the second-cycle level), or possess equivalent qualifications. A completed master's thesis (preferably in mathematics or applied mathematics) is required before employment. Proficiency in English equivalent to English B/6 is mandatory. Additional merits include coursework in numerical methods for partial differential equations and functional analysis, programming skills (e.g., Matlab or Python), international experience, and excellent written and spoken English. Strong motivation for doctoral studies, critical thinking, and good communication skills are essential.

The position is fully funded, offering a monthly salary according to KTH’s doctoral student salary agreement and full employee benefits. The employment is for up to four years, with the possibility of renewal. The application deadline is April 30, 2026. For further information, contact Dr. Kristin Kirchner at [email protected].

To apply, submit your application via KTH’s recruitment system, including your CV, application letter, diplomas and grades, proof of language requirements, a copy of your master’s thesis or writing sample, and contact information for at least two references. Ensure all documents are submitted by the deadline.
