Numerical and computational modelling of the Wheatley aortic valve
Dr Hugo Oliveira, Department of Structures, State University of Campinas, Brazil
Location: Room WC203, Wolfson bld, University of Strathclyde
Date: Wednesday, December 3 at 2:00 pm
Abstract: Recent studies have indicated an increase in cardiovascular diseases in developing countries, particularly valvular disorders caused by rheumatic fever, which are affecting younger populations. In severe cases, when the natural valve cannot be repaired, replacing it with a prosthetic valve may be the most effective way to ensure the patient's survival. Existing artificial valves have limitations, such as early deterioration and the risk of clot formation. To address these issues, the Wheatley Valve introduces an innovative S-shaped leaflet design that enhances the washout effect in the aortic root, thereby reducing the risk of thrombus formation and the need for extensive antiplatelet therapy. In this talk, we will discuss the main elements needed to build a fluid-structure interaction computational model able to represent the real behaviour of the Wheatley valve and which can be readily extended to other valve designs.
Biography: Dr Oliveira has worked as Assistant Professor and Researcher in Computational Continuum Mechanics at University of Campinas (Unicamp), Brazil, since 2023. After his PhD in Structural Engineering from São Carlos School of Engineering, University of São Paulo, in 2017, he joined the prominent Laboratoire de Mécanique et Technologie of the École normale supérieure Paris-Saclay, France, to develop numerical techniques for model identification of sensitive structural systems. Later on, he returned to the University of São Paulo to work as Researcher in the field of structural optimisation (shape, dimensional and topology). In 2021 joined the Laboratoire d'études mécanique sismiques of the Commissariat à l'Énergie Atomique et aux Énergies Alternatives, in France, to work on formulation and implementation related to Damage Mechanics and post-critical equilibrium regimes. Dr Oliveira 's scientific career was redirected towards biomechal systems when he joined the Institute of Mathematical and Computer Sciences at the University of São Paulo (2022) to build a fluid-structure model of the Wheatley Aortic Valve, which was awarded the best USP Earth and Exact Sciences in 2024. He was a visiting researcher at Polytech Clermont-Ferrand (2015) and at the National Institute of Science and Technology for Scientific Computer-Assisted Medicine (INCT MACC - HeMoLab/LNCC) in 2022. In 2023, Dr Oliveira was invited by the Brazilian Parliament to present research involving in-silico modelling of the Wheatley valve arising from a fruitful partnership with Dr Sean McKee, Dr David Wheatley, Dr Iain Stewart, Dr José Cumitato and Dr Gustavo Buscaglia. In 2024 he was a member of the Virtual Physiological Human Institute for Integrative Biomedical Research.
In recent years, Dr. Oliveira research has focused on theoretical and computational investigation of single and multi-physics systems for biomedical applications such as heart valves, ventricular assist devices for children, modelling and integration of the full cardiovascular system, crimping and deployment of prosthetic valves and modelling the infusion of haemodialysis catheters. His research has been funded by Brazilian agencies such as Fapesp, Funcamp and CAPES. Dr. Oliveira has authored one book chapter, 27 conference papers and published 23 peer-reviewed journal articles in the field of Computational Mechanics.
Climate, Chaos, and Covid
Prof Chris Budd, Institute for Mathematical Innovation (IMI), University of Bath
Location: Online (Zoom) - Link: https://uofglasgow.zoom.us/j/85757290439?pwd=J7BFNM5zGh1w1qlc9yPFbmpBufQKad.1
Date: Thursday, December 4 at 2:00 pm (UK Time)
Abstract: I will talk (with examples) about my work in climate change, modelling Covid-19, machine learning, and other areas of knowledge exchange and working with industry. This will include explaining some of the mechanisms behind study groups, virtual and face to face. I will also describe my work in public engagement, including being Gresham Professor, Bath Taps into Science, and Masterclasses. In all cases I will show the strong links between this activity, research (including REF impact), and teaching. The title is taken from my recent popular book on the same subject.
