Paul Lerner

I’m a postdoc researcher at Sorbonne Université, CNRS, ISIR. I got my PhD in Multimodal Information Retrieval at Paris-Saclay University (LISN/CNRS lab). I’m currently working on Multilingual Large Language Models and Machine Translation with François Yvon. My PhD advisors were Olivier Ferret (CEA List) and Camille Guinaudeau (LISN). Before my PhD, I already worked with Camille but also with Hervé Bredin, about Multimodal Speaker Diarization, as a research engineer.

I have an engineering degree in Computer Science from ESILV and a master’s degree in Artificial Intelligence from Paris Descartes University (now Paris Cité). During these studies, I did two internships: one at ISIR/CNRS with Catherine Pelachaud and Beatrice Biancardi on Multimodal Human-Computer Interaction, and one at Télécom Paris with Laurence Likforman-Sulem on Parkinson’s Disease detection based on handwriting. See my resume for further details.

I’m broadly interested in Natural Language Processing, with a focus on resources and evaluation.

If you’re interested in my research, you can find a list of my publications here, and of my talks there. I advised several master students, learn about them here.

In 2025, I was awarded the DAAD AINeT fellowship that funded a week of travel to visit German labs.

I like to open source my research code and datasets, find a list of available resources here.

I’m also currently Teacher at Aivancity and Teacher Assistant at Sorbonne Université. During my PhD, I was Teacher Assistant at Paris-Saclay University and Polytech Paris-Saclay. During two years of my postdoc, I was Teacher Assistant at ENSAE (IP Paris). I was also lab monitor at LxMLS 2025. More about my teaching activities here.
