Ed worked on understanding and classifying heart sounds. He produced physical models to understand the causes of the heart murmurs associated with aortic stenosis and mitral regurgitation. He also used machine learning techniques to classify heart sounds as either normal or abnormal.

Oscar developed noise prediction methods for turbomachinery operating at low Reynolds number. Noise reduction of air-moving devices such as axial compressors is becoming increasingly important for the industrial engineer, as stringent regulations are placing acoustic design on near equal terms with aerodynamic efficiency. Consequently, noise can no longer be accepted as an undesirable by-product, but rather must be accounted for at an earlier stage, ideally in tandem with aerodynamic design. Oscar worked to implement low order models that can be used to assess noise levels early in the design process. This work involved using analytical models together with computationally demanding fluid dynamics simulations to devise quick but accurate methods for noise production. Oscar was also interested in utilising machine learning algorithms in optimisation for low noise design.
