Sandra Wienke is a doctoral candidate at RWTH Aachen University and works as a research assistant in the HPC Group of the RWTH's IT Center. She received her master's degree with distinction from Aachen University of Applied Sciences in 2009 where she studied Technomathematics with main focus on scientific computing. Her research interests include high-performance computing on parallel heterogeneous architectures. To this end, she is especially interested in the analysis of development productivity, cost effectiveness and performance of various programming models (e.g., CUDA, OpenACC, OpenMP) on many- and multicore systems. Since 2013, she engages in the SPEC High-Performance Group. Furthermore, Sandra Wienke provides support for parallel programming to researchers at RWTH Aachen University and gives regularly lectures and courses on this topic at universities, workshops and conferences.
