  • Mentee within the initiative of C40 Women4Climate Mexico City
  • Research & Development Engineer at Green-Basilisk B.V.
  • PhD candidate at Delft University of Technology, in the project “Bacteria-based self-healing concrete – from lab table to outdoor application” (Bio2Concrete)

Master of Science from Delft University of Technology, with a specialisation in Materials Science within Civil Engineering.

Bachelor of Built Environment from the Amsterdam University of Applied Sciences, with a specialisation in Structural Design within Building Engineering.


The main focus of research is bacteria-based self-healing concrete. Topics of research relate to various aspects of this theme. In order to motivate adoption of the invention to concrete practice, material development was oriented towards an additive, serving as an “add-on” innovation falling under the category of “admixture”. In order to promote applicability, research includes the development of quantitative methods and assessments of quality, functionality, sustainability and viability. 

Guest lectures and workshops on self-healing concrete and taking the approach of damage management, inspired by nature, e.g. for various (inter)national universities, institutions and companies.

Various demonstrations and hands-on activities related to (self)healing of concrete and asphalt, e.g. at (science) fairs and open days.
