Onderzoek

  • Onderzoek in discrete wiskunde, met focus op eindige meetkunde, (toepassingen in) codeertheorie en cryptografie en het gebruik van algebraïsche technieken.
  • Onderzoeksinteresse in computeralgebra en computationele wiskunde, ontwikkeling van specifieke algoritmen om bepaalde meetkundige structuren te onderzoeken.
