She is a previous co-director of the UCL Environment Institute and led the EPSRC-funded Bridging the Gaps: Sustainable Urban Spaces project at UCL which provided support for new research collaborations across 26 departments, involving 63 researchers.

Dr Mark van Loosdrecht

Dr Mark van Loosdrecht

Dr Mark van Loosdrecht is a full professor in the department of Biochemical Engineering at Delft University of Technology, and head of the Environmental Biotechnology section. He obtained his Engineering Degree in Environmental Engineering at Wageningen University and obtained his PhD with a focus on the adhesion of bacteria and the effects of adhesion on the microbial physiology at the same university in 1988. He has been lecturing at Delft University of Technology since 1988. He has been a scientific advisor of Water Cycle Research at KWR Water Cycle Research since 2008, and holds several fellowships and an honorary doctorate at the ETH Zurich. His research interests include the principles of microbial growth in biofilms and granules and the principles of metabolism in mixed microbial cultures under dynamic conditions, and one of his many academic achievements has been in the mechanistical understanding of biological phosphorus removal processes from wastewater and of the morphogenesis of biofilms. Currently four different wastewater treatment processes developed by his team are being introduced on a commercial scale.

Dr van Loosdrecht is Editor-In-Chief of Elsevier’s journal Water Research and has recently been awarded the Lee Kuan Yew Water Prize 2012 for his breakthrough contributions in creating sustainable solutions in the field of wastewater treatment. He has contributed a video interview to Elsevier’s Bigger Brains initiative, a platform that provides career guidance and advice for early career researchers.

He has a track record in developing multidisciplinary studies in chemical, environmental, ecological, water, and nano areas, ranging from fundamental science to applied engineering.

Hanny Maas


Engineer Hanny Maas is the Programme Manager of the Dutch WASH Alliance, an alliance of six non-profit organisations in the Netherlands, supporting over 70 civil society organisations in eight countries in Asia and Africa. The aim of the WASH Alliance is to create sustainable WASH services for poor and marginalised people. The WASH Alliance works with the FIETS sustainability principles, with the aim of creating financial, institutional, environmental, technological and social sustainability (www.washalliance.nl).

Hanny Maas has been a professional in the field of development cooperation for over 20 years. Her expertise lies in the field of micro-finance, business development, social enterprise, pro-poor inclusive development and the promotion of sustainability in a development context. She has previously worked at organisations such as Hivos, an NGO in The Netherlands, and has three years of experience in market research in the private sector.

She is passionate about creating job opportunities and sustainable services for poor people. Local businesses can be one of the main drivers for positive and sustainable change at the base of the pyramid, creating a win-win situation by opening up new markets for companies and by creating access to valuable services and employment for the poor. The big challenge in creating sustainable WASH services is to create partnerships between private sector, government and civil society and to develop business models that can scale and that are inclusive for marginalised people.
