I am a cosmologist interested in non-linear aspects of the evolution of the Universe and light propagation effects. My work focuses on tracing signatures of structures in the Universe, and studying how they affect cosmological observations.
Observing the Universe is like looking through a tank of water. In both cases observed images are distorted. In both cases the amplitude of distortions can be used to measure properties of the medium – for example an image of an object located behind a transparent tank full of water will be different when the water's temperature is 95°C than in the case when it is 5°C. Similarly, an image of a distant galaxy varies depending if its light have passed close to a large cluster of galaxies or if its light rays traversed through a cosmic void
In my work, I look for all kinds of distortions in images of far away objects, and by analysing these distortions I can study properties of our Universe.
