About Me

I am a 26-year-old researcher who recently earned a Ph.D., having successfully defended my thesis at Inria Rennes in France. As a sociable and meticulous person, I bring forth exceptional multitasking abilities and a demonstrated resilience to high-stress situations.

My expertise lies in the fields of explainability (XAI), natural language processing (NLP), and human-computer interaction (HCI). During my doctoral research, conducted under the guidance of Christine Largouët and Luis Galárraga from the LACODAM team, I focused on the Automatic Construction of Explanations for AI Models.

In the current landscape of advanced AI, particularly in deep learning, the escalating complexity of models raises concerns about trust. Relying on black-box solutions poses challenges for technical, ethical, and legal reasons. My Ph.D. aimed to address these issues by extending interpretable methods for machine learning, shedding light on the inner mechanisms of complex models.

Having explored avenues such as generating artificial instances to enhance explanations during my Ph.D., I am now eager to apply and further refine these skills in a professional setting. I am actively seeking opportunities to contribute to and advance the field of generative AI, with a particular focus on NLP.

Work experience

2020 - 2024

  • PhD student supervised by Christine largouët and Luis Galárraga in the domain of interpretability
  • My Ph.D. focused on two tasks, firstly I studied the technical aspect of explanation, before moving on the human aspect. I hence studied when are linear explanations adapted to a model and target instance that leads to a publication in CIKM 2022. Following this, I visited the Human-Centred Computing group and conducted user studies to measure how feature-attribution, counterfactual, and rule-based explanation methods affect the users' trust and understanding.

    2022 - 2023

  • Visiting Researcher at Aalborg University in Danemark
  • In collaboration with Niels van Berkel, I conducted user studies to quantify the impact of three well-known explanation techniques (feature-attribution, rule-based, and counterfactual) on users' trust and understanding. This visit ended with the submission of a paper at VIS 2023.
    I have been lucky to meet a group of extremely talented and friendly colleagues there. Together we worked on two additional projects that lead to the publication of workshop papers at CHI 2023.

    2020

  • Internship supervised by Luis Galárraga and Christine largouët
  • I completed my research master's degree with a six months internship at Inria Rennes. This internship was part of the FABLE project (that leads to my PhD thesis.) I proposed a better discretization method to improve Anchors for tabular data and extended the latent research space used by Anchors to generate textual explanation. This internship ended with a publication in CIKM 2020.

    2018

  • Internship supervised by Luis Galárraga.
  • I completed my bachelor degree with a four months internship in a research laboratory. This was my first foot in the research, and I never leave it after. This internship in the domain of semantic web ended with the publication of an article concerning the mining of referring expressions in EDBT 2020. During this internship I coded a programm called REMI, supervised by Luis Galárraga.
