During my master’s thesis research in physics on the topic “Simulation and Visualization of Gravitational Waves from Binary Black Holes” at the University of Konstanz, I realized the current need for effective tools to process mathematical formulas in document analysis and Mathematical Information Retrieval (MathIR).

Since then, I review, develop, and evaluate Mathematical Entity Linking (MathEL) methods and applications. Methods include STEM document (formula & identifier) annotation recommendation, formula concept retrieval (classification & clustering), and nearest-neighbor retrieval. Applications include mathematical (STEM) document classification & clustering, Wikipage readability & accessibility, formula search, question answering, and question generation. Particularly, I am focused on the Wikidata knowledge graph.


  • Mathematical Information Retrieval (MathIR)
  • Mathematical Entity Linking (MathEL)
  • Formula search
  • Math document classification & clustering
  • Question answering
  • Question generation
  • Recommender systems
  • Wikipedia & Wikidata


The following list illustrates examples of the student projects (see pdf file here). Feel free to contact me if you have interest in any of these or my other research topics.
