Mariska Ronteltap PhD, MSc

Senior Lecturer in Sanitary Engineering

Biography

Mariska Ronteltap holds a Masters' degree in Environmental Engineering from the University of Wageningen, the Netherlands and a PhD from the Swiss Federal Institute of Technology Zurich (ETH) and Swiss Federal Institute of Aquatic Science and Technology (EAWAG), Switzerland. She also has a university teaching qualification (UTQ) from the TU Delft.

At IHE Delft, Mariska is involved in research (>945 citations, h-index = 12) and education on MSc level (mentored >40 students) and PhD level (graduated 2 research fellows, currently supervising 1 PhD fellow) and several online courses, and has been part of research and capacity building projects for both the public and private sector, all in the field of sanitation.

Main fields of interest cover:

Memberships include International Water Association (IWA) and Sustainable Sanitation Alliance (SuSanA); for IWA, Mariska is the Secretary to the Specialist Group on Resource Oriented Sanitation.

Main activities:

  • Post-graduate education on Sanitary Engineering (graduate level, distance learning, training and capacity building).
  • Research on Sanitary Engineering, particularly in poor urban settings and recovery of nutrients, water and energy (PhD and MSc supervision).
  • Projects in the field of Sanitary Engineering and Capacity Building.
