My research focuses on the design, analysis and implementation of efficient algorithms
in algebraic topology, computational geometry, real algebraic geometry,
and symbolic computation, with the goal to bridge the gap between mathematical theory and
application areas. My current emphasis lies on the theory of persistent homology
and its applications in the analysis of scientific data.
