Andrea Ghezzi

PhD Student

Short Bio

Andrea Ghezzi was born in Bergamo, Italy, in 1996. He obtained his Master degree cum laude in Automation and Control Engineering from Politecnico di Milano with a thesis about stochastic MPC with constraint prioritization. From December 2020 to September 2021 he was a researcher at Data Science R&D Department of Tenaris Dalmine, working on virtual sensing for improving the steel making process. From October 2021 he joined SYSCOP Laboratory at University of Freiburg, carrying out a PhD under the supervision of Prof. Dr. Moritz Diehl. He is a Marie-Curie fellow of the ELO-X project.
