Kai Lawonn’s research on data visualisation ranges from medical visualisation and illustrative visualisation to geometric computing, computer graphics and visual analysis. In his work, Lawonn develops new theoretical concepts which he always links to applications in fields as diverse as medicine, chemistry and heritage conservation. He is a mathematician who has achieved enormous thematic breadth in an exceptionally short time: he completed his doctorate and habilitation in Magdeburg within five years, as well as conducting research at TU Delft and the ETH Zurich. The international contacts established at the latter institutions have resulted in numerous (co)publications in high-ranking journals. Lawonn has received several grants for his investigative work, including DFG research grants. One of the distinctions he has won that is particularly worthy of mention is the EuroVis Young Researcher Award 2020, a prize for outstanding young researchers in the field of computer graphics and visualisation.
