CV

I’m a cognitive scientist with a strong technical and theoretical background and more than 15 years of experience in interdisciplinary teams. I design cognitive science experiments with high precision and technical reliability using entirely free and open-source tools; openness and reproducibility are my focus. As I finish my PhD, I’m looking for a lab to host me as a postdoc, where I can work as part of a team. If you think I could be a good fit, please get in touch. Find my CV here
