Shigehiko Schamoni, M.A.

「シャモニ滋彦」

In May 2023 I started a new position as Compute Lab Manager at the Institute of Computer Engineering (ZITI) at Heidelberg University. I am responsible for planning, extending, and optimizing the scientific compute infrastruture of various research groups at the institute.

Currently, I’m finishing my PhD thesis under supervision of Prof. Dr. Stefan Riezler at the Statistical NLP group of Heidelberg University.

Research Interests

  • Cluster Computing / HPC
  • Medical Data Analysis
  • Speech Translation
  • Grounding in Machine Translation
  • Cross-Language Information Retrieval
