My main interest are centered around environmental chemistry and its implications in water treatment with specific expertise in adsorption, polymers, dissolved organic matter, ozone, metals, reaction kinetics, analysis and disinfection by-products.

During my PhD-studies I used polymer adsorbents for the purpose of treating metal-containing water and wastewater, including both applied and basic research work. During my time in Switzerland and the Swiss Federal Institute of Aquatic Science and Technology (Eawag) I continued the work but turned into oxidation (particularily ozone), and reaction kinetics 

The post-doctoral project is entitled “Role and change of dissolved organic matter during oxidative water treatment: From competition to prediction of micropollutant abatement”, and aims to characterize and better understand the interactions between oxidants and dissolved organic matter (DOM). This will result in a widen knowledge about the reactivity of DOM. The research, which is of a fundamental character, is focused on a kinetic assessment including oxidation reactions with a range of different oxidants, measurements of donating- and accepting capacities of DOM as well as sophisticated analysis involving mass spectrometry.
