Begüm Tanis is an assistant professor in the Department of Water Management at Delft University of Technology. Her research focuses on both the fundamentals and applications of membrane-based water treatment processes, including drinking water production, concentrate management, and the treatment of alternative water sources for drinking, industrial, and agricultural use.

Begüm received her PhD in 2020 from the Singapore Membrane Technology Centre (SMTC), part of the Nanyang Environment and Water Research Institute (NEWRI) at Nanyang Technological University (NTU), Singapore. She continued working at the same institute as a research fellow until late 2021. Her work combined experimental and computational approaches to investigate membrane fouling mechanisms across a range of applications—from nanofiltration to microfiltration—targeting oily wastewater, industrial water (e.g., biocatalyst separation, pharmaceutical processes), complex streams involving organic solvent–water mixtures, and microplastics. Before joining TU Delft, Begüm worked at the Technical University of Denmark (DTU) as a postdoctoral researcher, where she focused on forward osmosis and reverse osmosis processes, for applications such as ultrapure water production, osmotic cold concentration for pharmaceutical and food & beverage industries, and resource recovery.

Her academic journey has been recognized with awards, including the Singapore International Graduate Award (SINGA) in 2015, the Women in Engineering, Science, and Technology (WiEST) Grant in 2021, and the Delft Technology Fellowship (DTF) in 2023.
