This postdoctoral position at KTH Royal Institute of Technology focuses on high-performance computational fluid dynamics, specifically the development of software and numerical simulations for turbulent flow in complex geometries. The research will involve working with direct numerical simulation codes such as Neko and PyFR, contributing to advancements in computational physics and fluid mechanics. The successful candidate will join a dynamic and creative environment at KTH, a leading international technical university committed to education, research, and innovation for a sustainable society. The position is a full-time, temporary appointment for up to two years, offering attractive benefits and good working conditions. Applicants must hold a doctoral degree or equivalent, possess an outstanding research and publication record, and demonstrate strong analytical and problem-solving skills. Proficiency in English is required for presenting and publishing research results. Preferred qualifications include a recent doctoral degree (within the last three years), teaching abilities, awareness of diversity and gender equality, collaborative skills, and expertise in high-performance computational fluid mechanics. The application process requires submission of a CV, diplomas, grades, translations if necessary, representative publications or technical reports, a recommendation letter, and contact information for two references. The position may be subject to security clearance under Swedish law. KTH values equality, diversity, and equal opportunities as integral to its core values.
