Research Interests

  • Microbiological and process technological aspects of water treatment and transport
  • Biofouling, biofilms, hydraulic biofilm resistance, biological stability, microbial (re)growth.
  • Fouling control of membrane systems (e.g. RO, NF, UF, FO) and cooling towers. 
  • Sensors and tools for (i) early detection and in-situ non-destructive (bio)fouling/biofilm monitoring and characterisation and (ii) rapid sensitive microbial water quality monitoring.
  • Numerical modelling of fouling and water treatment system performance.
  • Dynamics of microbial ecology of (drinking) water distribution systems.​
