Research interest

My current research interest includes:

  • The suitability of (marine) phages as biological tracers in porous media. With this aim, I use physical and biological quantification methods to reveal the changes of tracer phages during their transport in laboratory system and under field conditions.To a larger scale, I am also interested in identifying facilitating and retaining environmental factors for phage transport
  • The mycosphere as an environmental factor for phage transport and phage-bacteria interactions. To this end, I am particularly interested in the physico-chemical and biological interactions of (pro)phage, bacteria and the fungal mycelia at microscale (by microfluidic device) to centimeter-scale.
