Jules van Lier is full professor of Environmental Engineering and Wastewater Treatment at the Sanitary Engineering Section of Delft University of Technology and has a 1-day-per-week posted position at the Unesco-IHE Institute for Water Education, also in Delft. Jules van Lier accomplished his PhD on Thermophilic Anaerobic Wastewater Treatment in 1995, under the supervision of Prof. Gatze Lettinga at Wageningen University.

Throughout his career, he has been involved as a senior researcher / project manager in various national and international research projects, working on cost-effective water treatment for resource recovery (water, nutrients, biogas, elements). His research projects are focused on closing water cycles in industries and sewage water recovery for irrigated agriculture.

The further development of anaerobic treatment technology is his prime focus. In addition to university work, he is an Executive Board Member and Scientific Advisor to the LeAF Foundation; regional representative for Western Europe Anaerobic Digestion Specialist group of the International Water Association (IWA); editor of scientific journals (e.g., Water Science Technology and Advances in Environmental Research and Development); member of the Paques Technological Advisory Commission; and member of the Advisory Board of World-Waternet, Amsterdam.
