معرفی
Roger Pierre Dufresne is a Research Fellow at the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge, focusing on atomic astrophysics. He holds a BSc in Physics from the University of Leeds (1991-1994) and a Master of Advanced Study in Mathematics (Part III) from the University of Cambridge (1994-1995). After a career as a troubleshooting accountant and finance manager (1995-2017), he pursued a PhD in DAMTP (2017-2022), followed by roles as a visiting researcher (DAMTP) and research study administrator in Medical Genetics (2022-2023).
His research centers on improving atomic process modelling in plasma, particularly for solar atmospheric diagnostics. Current work addresses ionization equilibria in the solar corona and transition region, incorporating density-dependent effects and radiation-driven processes. This advances understanding of plasma properties like temperature, density, and chemical abundance in lower solar atmospheres.
Research Groups: Astrophysics, Atomic Astrophysics
Publications span advanced atomic database development (CHIANTI project), solar UV spectroscopy comparisons, and benchmarking atomic models against observational data. His work bridges computational astrophysics with empirical solar observations.
