Lachlan Kelsey

Lachlan Kelsey is an Adjunct Research Fellow at the UWA Medical School, affiliated with the UWA Centre for Medical Research and the Harry Perkins Institute of Medical Research. His work focuses on hemodynamics, cardiovascular disease mechanisms, and medical device innovation. He holds a PhD and has contributed to over 34 peer-reviewed publications since 2015.

His research interests include computational fluid dynamics (CFD), vascular physiology, and translational medical engineering. Key areas of study involve endovascular aneurysm dynamics, coronary plaque activity, placental vascular networks, and peripheral intravenous catheter design. His work addresses clinical challenges such as aortic dissection repair, microgravity-induced circulatory changes, and pandemic-related PPE manufacturing.

Notable contributions include developing novel CFD models for predicting aneurysm progression and co-inventing a peripheral IV catheter design that reduced failure rates in porcine models. His 2021 Western Australian Innovator award recognized advancements in cardiovascular device innovation.

Collaborations span institutions globally, with projects funded by health research grants. Supervision includes one doctoral student completing a thesis on vascular access technologies. His lab integrates biomedical engineering, clinical imaging, and mechanobiology to advance personalized vascular care.
