Davi Castro Silva received his PhD in Applied Mathematics from the University of Cologne (Germany) in December 2021, under the supervision of Prof. Frank Vallentin. He then became a postdoc at CWI (the Netherlands) and a member of the quantum computing group QuSoft. He will be joining RoaRQ in January 2024, working in Cambridge with Sergii Strelchuk, Tom Gur and Anuj Dawar. Davi’s research interests are broadly distributed across quantum computing, computational complexity theory and combinatorics; he is most interested in problems where the interplay of ideas from different areas is particularly important.
