Researcher biography
Dwayne Mann is an early career researcher, having recently submitted his PhD thesis in Biomedical Engineering. His thesis developed non-invasive methods to objectively describe the severity of airway obstruction on a breath-by-breath basis. His work bridges the gap between highly interventional physiology sleep studies and the clinical sleep environment and helps to characterise obstructive sleep apnoea patient phenotype, which could ultimately be used to direct patient treatment. When he isn't writing MATLAB code, he spends most of his time running around after his children.
