Dr. Mehmet Sarp Yalim received his Ph.D. in Engineering Sciences from the Free University of Brussels (ULB) in Belgium in 2008. He had a joint postdoc appointment at the Center for mathematical Plasma Astrophysics at the Catholic University of Leuven (KU Leuven) and Department of Solar Physics at the Royal Observatory of Belgium between 2008 and 2013. During his appointment, he was also a member of the Science Center for European Space Agency's PROBA2 Satellite located at the Royal Observatory of Belgium.

Sarp joined the Center for Space Plasma and Aeronomic Research (CSPAR) at The University of Alabama in Huntsville (UAH) in July 2015. He is a Research Scientist at CSPAR in UAH. He is also the Program Coordinator of the UAH CSPAR/NASA Marshall Space Flight Center Heliophysics NSF Research Experience for Undergraduates (REU) Program. He was awarded the S.T. Wu CSPAR Performance Award in 2019 for outstanding performance within the Center. His main research interests are solar physics, space weather, computational fluid dynamics, numerical methods, scientific code development, and parallel computing.
