About

Dr John Hart is a senior research fellow at the Centre for Sports Engineering Research. John is a design and fluids expert specializing in computational Fluid Dynamics (CFD), and the application of reverse engineering and 3D imaging. He delivers engineering solutions to a wide range of clients within the sports and healthcare sectors.

John studied at Sheffield University (obtaining a MEng degree in Mechanical engineering). He then continued at Sheffield University to complete his PhD in computational fluid dynamic analysis of supersonic ejectors, and joined CSER in 2003.

Current projects involve the development of novel sports projectiles working with a range of international clients. He is also involved in the development of equipment for use by dysphagia sufferers and their carers, in collaboration with Sheffield Teaching Hospitals, funded by the Abbeyfield Research Foundation. He has also assisted FIFA with the development of equipment safety standards, and continues to work with other clients in understanding the efficacy of their safety equipment.

John has previously worked with British teams, such as British Cycling, and athletes in their preparations for the Athens, Torino, and Beijing Olympic games. In particular he worked with British Skeleton Bob Sled, as part of the UK Sport funded Innovation Program in preparation for Vancouver 2010. British Skeleton took the only British medal at the Vancouver games, a Gold for women’s Skeleton Athlete Amy Williams. Most recently he worked closely with Badminton England on product development, funded under the Sport England Innovation Fund. This work has recently been referenced in the Inspired by 2012: The legacy from the Olympic and Paralympic Games - a joint UK Government and Mayor of London report. He also provided CFD consultancy to Ping Golf, work that led to the development of their G30 driver with turbulator technology, a #1 selling driver in Europe and the USA. Images from his work featured in a solo exhibition at the Royal Institution in London, and were subsequently featured in the Aperture feature in New Scientist.

In addition to his research John is course leader for MSc Sports Engineering and lectures on a number of modules at Sheffield Hallam University: MSc Sports Engineering, Computer simulation of sports equipment, MSc Sports Engineering, Innovation and enterprise in sports engineering, BSc Sport Exercise Technology, Design and prototyping, and is the department resident photographer.
