As a Ph.D. researcher of the RTG 2450 in program P3, I work within the CoMMAS and SDL Materials Science groups at SCM, focusing on multiscale modeling of chemical reactions. My research integrates various computational approaches to bridge different time and length scales, with a particular emphasis on kinetic Monte Carlo simulations for capturing reaction dynamics. Additionally, I quantify uncertainties in these models to improve predictive accuracy, ensuring robust and reliable simulations for complex chemical systems.
