Biography

Alys Clark obtained her Bachelor of Arts (Honours) in Mathematical Sciences from the University of Oxford and her Masters and PhD degrees in Applied Mathematics at the University of Adelaide. She joined the ABI in 2008 as a Postdoctoral Research Fellow in the Lung Research Group and now is one of the lead researchers in that group, as well as leading an active research group in reproductive health and development. Alys is a current awardee of a RSNZ Rutherford Discovery Fellowship (2014), and the JH Michell Medal for Applied Mathematics (2017).

 

Research | Current

Alys’ research interests focus on understanding how we get oxygen from our environment, before and after birth, and using this new knowledge to improve diagnosis and treatment strategies when things go wrong. Alys develops computational models of lungs, placenta and ovaries, which account for complexities in their structure and can predict the impact of disease on organ function. Her expertise lies in developing efficient and reliable methods for modelling physical processes that occur simultaneously in complex networks of tissue and blood vessels.

Placental health 

Abnormal vascular stucture in the uterus and placenta have been implicated in serious complications of pregnancy, such as intra-uterine growth restriction and pre-eclampsia. We aim to construct structural and functional models of the placenta uterus throughout pregnancy that can help to detect problems earlier and more reliably.

Lung health

The impact of lung disease on daily life is considerable, with sufferers often unable to go about activities without becoming short of breath. Lung disease often starts small, via tiny changes in lung tissue structure, and is often undectable in conventional CT imaging until significant damage is done. We aim to develop new models predicting the impact of lung disease on an individual, and new image analysis tools to improve detection of disease before it becomes severe. Importantly, we consider how age (young and old) modifies disease impact, and so should be considered in treatment planning.
