About Me

I am Nicolas Weber, researcher in the Intelligent Software Systems Group at the NEC Laboratories Europe. Before, I was Ph.D. student at the Graphics, Capture and Massively Parallel Computing Group at TU Darmstadt. My Ph.D. topic was on automated performance optimizations for GPU array access. In my research I mainly focus on performance optimizations for GPU based applications in the High Performance Computing (HPC) and Artificial Intelligence (AI) applications.
