Stellenbosch University, South Africa

• Developed machine learning systems for detection of tuberculosis (TB) and COVID-19 from cough, breath, and speech recordings collected in real-world clinical environments.
• Designed deep neural network architectures incorporating autoencoders, attention mechanisms, transfer learning, and generative models for respiratory disease classification.
• Designed signal-processing workflows for noise-robust analysis of real-world speech, cough, and respiratory audio, evaluating how environmental noise, recording-device variability, and signal quality influence model performance.
• Modelled cough frequency and recovery trajectories using acoustic analysis, language-model-based temporal modelling.
• Built AI-driven patient monitoring solutions integrating audio sensing and accelerometer data through custom Android applications in real-world environments.

• Senior Investigator in the international (CAGE-TB) study.
• Architected and deployed an end-to-end clinical data acquisition and processing pipeline, integrating microphones, servers, and mobile sensing platforms, and developing scalable Python workflows for preprocessing, annotation management, storage, and model-ready dataset generation.
• Developed standard operating procedures (SOP) and trained healthcare workers in the deployment of AI-enabled sensing technologies within TB clinics.
• Co-supervised honours and MSc students working on pathological speech and cough analysis using reinforcement learning, transformers, and NLP methods.
• Delivered deep learning training materials covering CNN, LSTM, and ResNet architectures using PyTorch and TensorFlow.
