Sandro Pezzelle
Assistant Professor in Responsible AI at the ILLC, Faculty of Science, University of Amsterdam. Studying, teaching, and advancing language-mediated intelligence in humans and machines. As such, my research combines insights and methods from Natural Language Processing (NLP), Machine and Deep Learning, 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 affiliated with the Dialogue Modelling Group, 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 Large Language Models represent words, phrases, and sentences (in context)
- Language and vision: reasoning, linguistic, and communicative abilities of visually-grounded LLMs
- Cognitive mechanisms in human semantics: how speakers acquire, use, and adapt their mental representations
- Interlocutor-aware text generation: can LLMs tune their style or knowledge to that of an interlocutor?
- Behavioral and mechanistic interpretability: what are the abilities of LLMs and where/how they occur in the computational graph
