PhD Student@University of Sussex in @NeuroFishh lab. MSc Neuroscience@University of Tübingen. Interested in visual neuroscience, neural design, evolution.
Joined June 2019
Some personal news: Definitely disheartened to be physically leaving behind @uni_tue @TueNeuroCampus and the labs of @teulerlab and @CellTypist, but thrilled to be soon moving for my PhD to @SussexUni and the lab of @NeuroFishh, with prestigious funding from @LeverhulmeTrust! 1/2.
