Buddhi Wickramasinghe works on audio and speech signal processing, with a focus on detecting spoofed or 'replayed' audio recordings (a security concern for voice authentication systems) and on designing adaptive front-end filters that help machine learning models process sound more effectively. Related work also touches on continual learning (methods for AI systems to keep learning over time without forgetting), as well as some applied projects in virtual reality-based stroke rehabilitation and image classification.
Publication output over the last decade has been irregular, with occasional gaps followed by bursts of activity, and averages about 1.4 publications per year over the last five years.
