Dr Panagiotis Chatzistergos

Associate Professor

School of Life Sciences and Education

My educational background is in the areas of Mechanics of Materials, Computational Mechanics and Biomechanics and my research is focused on enhancing the diagnosis and clinical management of various pathological conditions through the combined use of non-invasive in-vivo mechanical testing and computer modelling. I joined Staffordshire University in 2012 as part of an EC funded project aiming to advance scientific knowledge in the area of diabetic foot management and footwear prescription (http://www.diabsmart.eu/partners.php).
