Rihan Hai received her master degree in June 2012 from School of Information, Tsinghua University. Later she has joined SAP as a technical consultant. Since May 2015 she has been working as a research assistant at the Chair of computer science 5 (Information Systems) at RWTH Aachen University. Her research focuses on data lakes, especially metadata management of heterogeneous data. She has been working in different projects covering various applications of data lake systems. In August 2020 she received her PhD from RWTH Aachen University.
