The two year Master program in Data Science is built on the Data Science B.Sc. program and can be started in either the spring or fall semester. It is a joint project of the Faculties of Statistics, Computer Science and Mathematics. As the tasks are always and rapidly changing in this research field, the study program provides a sound statistical and mathematical theory and teaches contemporary methods and knowledge. Hence, the students are capable to do scientific research, have a scientific awareness and can trade it responsibly. The interdisciplinary ability to communicate about methods and their application, especially at the interface between statistics, computer science, mathematics and fields of application, is a key aspect of the study program.
