My research is about how nanosized materials afffect the environment. We study this by exposing fresh water organisms to nanoparticles of different materials and sources, and observing the affects as death, metabolic changes and reproductivity. One special outcome of the exposure is what proteins and other biomolecules the nanoparticles bind to and how it affects the proteins structure and function.

Lately, nanoparticles from plastics, nanoplastics, have become the main area. The reason is that plastics is a troublesome pollutant in our waters. We use polystyrene nanoparticles as model particles, but as breakdown nanoparticles in nature are expected to be different we break down consumer plastics and isolate the smallest size fractions for our exposure experiments.
