Profile

About

I am a Machine Learning Engineer specialising in Speech Technology. My research focuses on improving the generalisation and robustness of machine learning models for speech processing in the presence of distribution shifts, uncertainty, and dataset bias. I also explore the theoretical foundations of machine learning, particularly information theory, learning algorithms, and inference. At TCG CREST, my activities span applied research to advance speech technologies, postgraduate teaching, and various institutional responsibilities.
