GIACOMO BORIN
Hello, Iโm Giacomo. I enjoy Algebra and Cryptograph. Currently, I am pursuing a Ph.D. at the University of Zurich in the Applied Algebra group, while also working as a Pre Doc researcher at IBM Research Zurich within the Foundations of Cryptography group, under the supervision of Luca De Feo.
My mathematical pursuits primarily revolve around isogenies and isomorphism problems associated with coding theory. The objective of my research is to leverage these mathematical tools to establish innovative functionalities for cryptographic schemes, mainly threshold systems, based on quantum-resistant assumptions.
