Dr. John Kelley MMath. PhD.

Research Fellow


Summary

I am a Research Fellow in the Academy of Sport and Physical Activity and I specialise in Applied Computing and Sports Analytics. I am a member of the Sports Engineering Research Group through which I apply my skills to a great passion of mine - elite sport. I lead a research partnership with the Performance Data department of the English Institute of Sport, working with many Olympic and Paralympic teams, and I also work with the International Tennis Federation. I am based at the Advanced Wellbeing Research Centre which allows me to transfer my work with elite sport to health and physical activity applications. My teaching focus is on the Sports Engineering MSc, leading the Numerical Programming module.



About

I am a Research Fellow in the in the Academy of Sport and Physical Activity and I specialise in Applied Computing and Sports Analytics. My love of numbers culminated in a Master’s Degree in Mathematics from the University of Sheffield. I combined that with my love of sport in a PhD at Sheffield Hallam University, sponsored by the International Tennis Federation, to develop a method to measure the spin rates of tennis balls during competitive play.

I am now a member of the Sports Engineering Research Group through which I apply my skills to elite sport. I lead a research partnership with the Performance Data department of the English Institute of Sport. I work with Olympic and Paralympic teams such as Swimming and Boccia, creating bespoke data and video collection, processing, storage, and analysis tools to improve performance analysis methods. These systems incorporate mobile apps, cloud data storage and 3rd party software integration and allow high level data analytics through platforms such as Power BI.

I have continued to work with the International Tennis Federation, designing their world ranking methods for the Davis Cup and Billie Jean King cup. I created a computer model of both competition structures and optimised the ranking systems based using those models. I have also continued to provide analysis tools for tennis equipment testing. I am based at the Advanced Wellbeing Research Centre which allows me to transfer my work with elite sport to health and physical activity applications. An example application is working with British Weight Lifting to design a new event structure to encourage mass participation and friendly competition between men and women of different abilities, strengths and weaknesses.

The focus is to increase engagement and promote the maintenance of strength as people age. My teaching focus is on the Sports Engineering MSc, leading the Numerical Programming module where students use MATLAB software as a research tool and a tool to solve sports engineering problems. I also supervise students during their Industry Linked Project, for example investigating the ball properties of the latest Mitre football prototypes.
