- Profile
-
Jonni is a Lecturer in Verification at the Department of Computer Science. Before joining, in September 2021, he held research positions as a PI or a hired postdoc in a series of projects funded by the German Research Foundation (DFG), the Japan Society for the Promotion of Science (JSPS), the Research Foundation – Flanders (FWO), and the Academy of Finland (AKA).
Jonni received his MSc (2008) and PhD (2014) in mathematics from the University of Tampere, Finland. In 2020, he received the title of a Docent in Mathematical Logic from the University of Helsinki, Finland. His research interests originate from the general fields of finite model theory and logic in computer science. His research themes revolve around the interplay between expressivity and complexity of different logical formalisms, and in logical characterisations of complexity classes.
