About Me
I’m currently a 3rd-year PhD candidate at Multisensory Signal Analysis and Enhancement Lab (MuSAE), National Institute of Scientific Research (INRS) (Montreal, Canada), supervised by Prof.Tiago H. Falk.
My research is at the intersection of multi-modal signal processing and deep learning, with a focus on audio and speech analysis. My PhD research is centred around the development of generalizable, trustworthy, and secure audio representations. Some of the main application fields cover voice conversion/anonymization, deepfake speech and adversarial attack detection, respiratory sound understanding and health diagnostics. I also work part-time with Nectar on multi-modal sensor data analysis and machine learning for automated beehive monitoring.
Research Interests

- Deep Learning: Generalizable and explainable representations; Self-supervised learning
- Speech: Voice conversion and anonymization; Characterization of speech abnormalities
- Cybersecurity: Deepfake speech and adversarial attack detection
- Healthcare: Disease detection; sound event detection
