Eugen Betke has completed his study of computer science in 2015 with specialization on machine learning and I/O performance. In his master thesis he applied machine learning methods to predict I/O performance. At the beginning of 2016 he started as a researcher at the German Climate Computing Center. His key areas are analysis and optimization of HPC-I/O; he, for example, developed a cluster wide monitoring system for Lustre on Mistral. During his scientific career, he has acquired about three years of experience in these areas.
