Research interests

I strife to to realize a vision for smart and water sensitive cities and societies by innovating the ways we treat reclaimed and drinking water.

My research focuses on technology innovation. Specifically, I research novel advanced oxidation and reduction as well as membrane filtration. PhD projects I currently supervise e.g. investigate vacuum UV driven water treatment, membrane distillation, catalytic ozonation, and plasma treatment. My research on water treatment technology is typically strongly connected to controlling water quality hazards to end-users, including trace organic contaminants, disinfection byproducts, and also pathogens.

I also continue to expand my research in aspects of integrated water management and industrial water treatment, for example in the projects INVEST, SUGGEREIX and iWAYS. Here, I combine my broad expert knowledge on technology and water quality to find tailored solutions working in multidisciplinary teams to solve real world problems.

Selected research activities

In the NOWELTIES MSCA EJD PhD students Nikoletta Tsiarta (catalytic ozonation) and Amit Kumar (atmospheric plasma treatment) are aiming to submit their theses in 2023. The thesis of Amit Kumar links also to the PIAgri Cost Action that I participate in as management committee member on developing plasma technology for agriculture related applications. In the EU funded iWAYS project (start 12/2020) on industrial water and heat recovery we commenced to develop a robust membrane distillation process to recover water in the steel processing industry with another PhD student (Atefeh Tizchang) commencing in 2022. In collaboration with the Dutch technology centre of excellence Wetsus, I am co-developing vacuum UV technology for efficient emerging contaminants reduction in the scope of the supervision of two PhD thesis (Nimmy Kovoor George, finishing in 2022, Yicheng Wang, started 11/2021).

In integrated water management, I collaborate with several researchers from my host institution on the development of river basin models and decision support systems to support public authorities for taking investment decisions for wastewater treatment upgrades to achieve the goals of the water framework directive. Two competitive projects closely related are INVEST and SUGGEREIX, which both will finish in 2021.
