Pietro Lesci

I am a PhD student in Computer Science at the University of Cambridge advised by Andreas Vlachos.

I am interested in Natural Language Processing and Machine Learning. I am passionate about the science of language models: developing and applying causal methods—drawing from econometrics—to study the effect of training choices on models’ behaviour, including memorisation, shortcut learning, and tokenisation.

3+ years experience across research labs, consulting firms, and international institutions training custom models and developing data science solutions. Find my cv here .
