Your role

This is a fully funded position for 12 months in the HEXAPIC project, which is conducted in collaboration with Prof. Leon Kos's team at the University of Ljubljana.

The HEXAPIC project aims to develop a novel high-performance Particle-In-Cell (PIC) code for plasma physics simulations, leveraging the capabilities of exascale computing systems. By optimising PIC algorithms for modern heterogeneous architectures, including CPUs, GPUs, and other accelerators, the project seeks to achieve unprecedented efficiency and resolution in plasma simulations. This advancement will enable high-fidelity modelling of complex plasma processes, contributing significantly to fields such as fusion reactor design, material deposition technologies, and space propulsion systems. The project brings together a multidisciplinary team to push the boundaries of plasma physics and computational science.

The position holder will be required to perform the following tasks/will do research on the following topics:

• Contribute to the HEXAPIC project
• Carry out research in the predefined areas
• Disseminate results in top scientific venues
• Providing guidance to PhD and MSc students
• Participating in proposal writing 
• Participating in teaching activities
• Present results in international conferences and workshops

Your profile

• A PhD degree in Computer Science,  Physics or a related field
• Strong background in understanding plasma physics and computational plasma physics
• Excellent understanding of mathematical modelling, especially for plasma physics in 1D, 2D and 3D
• Experience with Particle-In-Cell (PIC) code development and kinetic models
• Experience in high-performance computing is desirable
• Sound publication track record in relevant international conferences and top journals
• Highly committed, excellent team-worker, and strong critical thinking skills
