Dr Toni Lassila


Toni has a doctoral degree in Mathematics with expertise in numerical methods in cardiovascular modelling, reduced order models, and uncertainty quantification. He has previously worked at the Ecole Polytechnique Federale de Lausanne and the University of Sheffield, before joining the University of Leeds in August 2018. He has co-supervised five PhD students in the past, and has been involved with several European projects (ERC and FP7/H2020).

Research interests

Toni's research interests are in the field of numerical methods for partial differential equations, specifically within the topics of reduced order models and uncertainty quantification. Applications of these methods can be found in the computational fluid dynamics simulations for the diagnosis and treatment of cardiovascular and cerebrovascular diseases. In the past, he has worked on the modelling of cardiovascular system, both in terms of the electrophysiology and the ventricular fluid dynamics. His current work focuses on combining patient-specific imaging and sensing with mathematical modelling to enhance the diagnosis and treatment of vascular diseases, while taking into account the physiological variability of vascular flow and its effects in the simulation model predictions. More recently, he is working on techniques for in-silico trials, meaning the generation of evidence through computational simulations on virtual patients to support the medical device R&D and approval process. He is also interested in deep learning generative models in synthetic image generation, and physics-informed neural networks for accelerating the simulation of cardiovascular problems.
