Bioavailability

Value Statement

We research the chemodynamics and microbial ecology of contaminant biotransformation for improved environmental (bio-)technology in natural and built environments.


Research Topics

Process-based description of the biotransformation and chemodynamics of organic contaminants in natural and built environments including:

  1. Ecology and bioavailability of contaminant biotransformation: Chemodynamics and microbial (bacterial/ phage) dispersal ecology for improved biotransformation and nutrient cycling .
  2. Mycosphere ecology (mycoremediation): ecology of contaminant biotransformation in the mycosphere; mycoremediation based on bacterial activation and dispersal by fungi (‘fungal highways’).
  3. Prediction of soil microbial pesticide degradation potential at the field scale: Combining proximal and remote sensing techniques with microbial activity analysis.
  4. Electrokinetics and electro-bioremediation: Use of electrokinetic approaches on the clean-up of contaminated matrices and water.
