David Weissbrodt, Assistant Professor

 with tenure track | Ph.D. | M.Sc. | Dipl.-Ing.

I benefit from a strong (inter)disciplinary curriculum in Chemical Engineering for Life TechnologiesEnvironmental Science & Engineering, and Biotechnology & Systems Microbiology. My academic track feeds on achievements in microbial systems, process engineering, water, energy, and health sciences. I harbour professional experience in the private sector.

I am active at (inter)national levels with professional service to several societies. I chaired with Marjet Oosterkamp the MMWWRR2017 Symposium on Microbiological Methods for Waste & Water Resource Recovery within TUDelft 175th Lustrum Technology for Life. I chaired with Merle de Kreuk the IWA Biofilms: Granular Sludge Conference 2018.

I received the inaugural IWA MEWE Early-Career Researcher Award from the Specialist Group on Microbial Ecology & Water Engineering of the International Water Association, University of Hiroshima, Japan, 2019. I was awarded one of the Best Teacher Awards of the Years 2017/18 and 2018/19 of the Master Track in Environmental Engineering. My science is intimately linked to teaching for the Life Science & Technology and Civil Engineering & Geosciences programs of the TU Delft.

The Weissbrodt Group for Environmental Life Science Engineering elucidates mixed-culture microbial systems designed for public health sanitation, environmental protection, biorefinery, resource and energy recovery from used streams.

Environmental systems biology and process engineering are combined in an approach of “process ecogenomics” to unravel mechanisms underlying the macro-scale, meso-scale, micro-scale, molecular, metabolic, and temporal performances of engineered and natural biological systems.

Specific research themes involve: 

  • Phototrophic microbial systems for nutrient concentration, bioproduct formation, and resource recovery.
  • Mechanisms of horizontal gene transfer and antibiotic resistance spread in urban settlements.
  • Microbial and metabolic networks of mixed-culture fermentation of green wastes.
  • Exopolymers biosynthesis and biorefinery from used aqueous organic streams.
  • Metabolic regulation in biofilm processes designed for aerobic-anaerobic ammonium oxidation.
  • Engineering microbiomes in intensified processes using granular sludge for biological nutrient removal.
  • The Netherlands Organisation for Scientific Research (NWO)
  • European Union Horizon 2020 Research & innovation Programme and Department of Science & Technology (DST)/Department of Biotechnology (DBT), Government of India (Saraswati 2.0)
  • European Union Horizon 2020 Twinning (REPARES)
  • Soehngen Institute for Anaerobic Microbiology (SIAM)
  • TU Delft Department of Biotechnology (BT)
  • Swiss National Science Foundation (SNF)

Teaching is a major activity of the Weissbrodt Group to educate and train the new generations of professional and scientific leaders.
