nLab Fosco Loregian

I am an Italian postdoc.

I’m a former student of Domenico Fiorenza. I owe him my mathematical everything.

I’ve been a postdoc in all these places:

• University of Western Ontario, (CA)
• Masaryk University (CZ)
• Max Planck Institute for Mathematics (D)
• Center of Mathematics, University of Coimbra (PT)

Currently, I am in Tallinn in the compositionality group of Pawel Sobocinski.

Here’s a list of the papers I’ve written: link

This is my personal website. It’s way more up to date than this page here…

Write me an email any time!
