Sandro Pezzelle

Assistant Professor in Responsible AI at the ILLC, Faculty of Science, University of Amsterdam. Affiliated with the Dialogue Modelling Group.
My research combines Natural Language Processing (NLP), Computer Vision, and Cognitive Science (see my current Research lines below). I published in ACL, EACL, EMNLP, NAACL, TACL, Cognition, and Cognitive Science.
Before, I was a Postdoc within the DREAM (Distributed dynamic REpresentations for diAlogue Management) ERC project led by Raquel Fernández. And, before, a PhD candidate at CIMeC, University of Trento, under the supervision of Raffaella Bernardi
(check QUANTIT-CLIC for some of my PhD work). In 2018, I was research intern at SAP AI Research.
I am a member of the ELLIS society, a faculty member of the ELLIS Amsterdam Unit, and a board member of SigSem, the ACL special interest group in computational semantics. I am part of TACL editorial team.
Research lines
Some topics I am interested in (contact me for theses and collaborations!)
- Computational semantics and pragmatics: how NLP models represent words, phrases, and sentences (in context)
- Language and vision: reasoning, linguistic, and communicative abilities of visually-grounded models
- Cognitive mechanisms in human semantics: how speakers acquire, use, and adapt their mental representations
- Interlocutor-aware text generation: can NLG models tune their style or knowledge to that of an interlocutor?
- Model interpretability: how and where large language models store their knowledge and skills
