Dr. H.M. (Henk) Jonkers


Henk Jonkers obtained his PhD in Marine Microbiology at Groningen University (1999) and worked until 2006 as research scientist at the Max-Planck-Institute for Marine Microbiology in Bremen and chairs since then as Associate Professor the Sustainability group within the Materials & Environment section at the CEG Faculty of the Delft University of Technology. His current research concerns development of innovative-, bio-based- and sustainable construction materials and he is scientific advisor of DUT spinoff company basiliskconcrete.com.


The sustainability groups research focus is on clarification of interactions between building materials/constructions and the living environment and consequences for both in terms of functional- and environmental performance over the entire life cycle. Further focus is on the development of innovative bio-based high performance construction materials such as self-healing concrete, as well as on development of construction materials and constructions with added benefit to the environment by integration of ecosystem functions provided by vegetation.
