I am a junior Lecturer and Researcher (ATER) at the University of Strasbourg, where I teach various Natural Language Processing (NLP) and Generative Artificial Intelligence (AI) related classes for humanities and linguistics students.

Previously, I worked as a Research Professor (post-doctoral position) on the Elderly Speech Korea Project, at Chosun University, South Korea, under the supervision of Professor Eon-Suk Ko. Here, my research focuses on analyzing linguistic biomarkers of cognitive impairment in neurocognitive disorders and Alzheimer’s dementia, using open-source NLP and AI tools for Korean long-form speech data. I am also involved in evaluating open-source AI tools for automatically transcription of child-directed speech in Korean, while using NLP tools to analyze lexical and semantic patterns for child language development studies.

Before South Korea, I did a two-year postdoc on the automatic processing of scientific articles on brain cancer and medical knowledge simplification using Large Language Models, at ATILF, University of Lorraine-CNRS, France, under Professor Mathieu Constant’s supervision.

I obtained my PhD in Linguistics and NLP from the University of Strasbourg, with the thesis “An Automatic Method for Building a Paraphrase Corpus” (open-source thesis in French), under the supervision of Professor Amalia Todirascu, University of Strasbourg, and Professor Dan Tufis from the Research Institute for Artificial Intelligence (RACAI).
