Sebastian is a doctoral student in the History of Science and Medicine. His research interests relate to the implementation of mathematical tools in the 19th/20th centuries. He is particularly interested in the (re-)use of these tools outside their original disciplines and the residue that is left on the math as it crosses epistemic and social boundaries in science. Before arriving at Yale, Sebastian worked as a researcher in condensed matter physics. He studied non-equilibrium electronic states, with the goal of understanding the interplay between magnetism and topology in candidate materials for high-efficiency electronics.
