I received my PhD from Le Mans University, where I conducted research at LIUM in collaboration with Orange Labs in Rennes, focusing on biometric authentication and security. I then joined the Center for Language and Speech Processing (CLSP) at Johns Hopkins University in Baltimore as a postdoctoral researcher. After four years there, I became an Assistant Research Professor in the Department of Electrical and Computer Engineering. I am now a tenured researcher (Chargé de recherche) at AMIAD in Palaiseau, France, where I continue to work at the intersection of speech processing, trustworthy AI, and security.

Research focus

Trustworthy and secured systems

My research lies at the intersection of speech and audio processing, machine learning, biometrics, and security. I develop methods for trustworthy and privacy-preserving speech technologies, with particular interests in speaker recognition, speech anonymization, deepfake and adversarial-attack detection, and the robustness of speech-processing systems. This work has included the IARPA-SHADOW, DARPA-GARD, and DARPA-RED projects.

Human centered conversational systems

I also study how foundation models and multimodal language models can support the analysis of spoken interactions. Through the EDART and SPEAR projects, my work has addressed speaker characterization, dialogue annotation, speech-aware language models, and the evaluation of conversational speech-to-speech systems.

Multimodal Healthcare applications

A complementary strand of my research investigates digital biomarkers for neurodegenerative disease detection and severity assessment. Within the NLS and ADPIE projects, I have worked with speech, handwriting, eye movements, and gait, including recent work on interpretable handwriting features for clinical assessment.

Service and Teaching

Teaching interests

Over the past four years, I have taught undergraduate and master’s-level courses in the Department of Electrical and Computer Engineering at Johns Hopkins University. I have also designed and developed an original course: “AI for Biometric Systems: Techniques, Applications, and Ethics”, which explores biometric systems and solutions through various lens, including practical labs to experiment on various modalities.

Service

I actively contribute to the speech research community:

• Session chair for CISS 2023 & 2025, Speaker Odyssey 2024, Euronoise Acousticum 2025, Interspeech 2025 & 2026
• Organizing chair of the Speaker Odyssey 2024 workshop in Québec city, Tutorial chair for the incoming Interspeech 2028 and the new IEEE ASLI 2027
• Reviewer for ICASSP, LREC, Interspeech, IJCNN, CISS, SLT, SPSC, Speaker Odyssey, ACL, and ICLR, Computer Speech & Language Journal and Transactions on Audio, Speech, and Language Processing Journal, and grant reviewer for the Johns Hopkins Artificial Intelligence and Technology Collaboratory.

Mentorship

I have supervised and mentored multiple undergraduate, master’s, and Ph.D. students on research projects involving speech technologies. I am committed to supporting motivated and capable individuals in developing strong research skills, from problem formulation and experimental design to publication and scientific communication.

I welcome national and international research collaborations and remain open to mentoring motivated students and early-career researchers. Students interested in future research opportunities can consult the Join Us page for current information and opportunities.
