André Greiner-Petter made his BSc and MSc in Mathematics at the TU Berlin in Germany. He has completed his Ph.D. at the University of Wuppertal in January 2022. During hhis Master’s thesis, he was a guest researcher at the National Institute of Standards and Technology (NIST) in the US and made a research internship at Maplesoft in Canada. After he finished his Master’s thesis in Germany, he started his Ph.D. at the University of Konstanz. He received multiple scholarships that allowed him to study at the National Institute of Informatics (NII) in Japan for the majority of his time as a Ph.D. student. Since January 2022, André works at the NII as a post-doctorate researcher.


André’s research focuses on Mathematical Information Retrieval (MathIR) tasks. The goal is to retrieve additional information about math content automatically and ideally fully understand mathematical expressions in natural language texts. Since this task is often considered difficult even for human beings, overcoming the issues require advanced approaches in a large variety of diffirent research fields, foremost information retrieval, natural language processing, and semantic analysis. Likewise, a successful system has several useful applications: from improved academic search engines to math-aware plagiarism detection systems, type assistance programs, and education purposes. In addition, this field lies directly in between computer science and mathematics. André’s primary research interest topics are:

  • Presentation to Computation Translations
  • Mathematical Information Retrieval
  • Semantic Document Analysis
  • Scientometrics
  • Data Science
