Dr Michael Thelwell PhD

Research Fellow


I am a Research Fellow in advanced human body measurement techniques and 3D surface-imaging for assessing physical health. My research interests include the use of 3D surface-imaging and advanced human body measurement techniques to improve the assessment of physical health. Currently working with collaborators at Leipzig University assessing human body shape within health applications (for example, the early detection of diabetes and metabolic syndrome) and developing improved methods of for chemotherapy dose prescription.


I am a Research Fellow in advanced human body measurement and 3D surface-imaging within the Sports Engineering Research Group at Sheffield Hallam University.

I graduated from Loughborough University in 2014 with a BSc in Sports Technology, during which I completed a year in industry working at PING Golf as an Analysis and Testing Engineer. I then moved to Sheffield Hallam University where I graduated with an MSc with Distinction in Sports Engineering before completing my PhD, titled 'Assessing human morphology using statistical shape analysis'.

Recently, my work has focused on how advanced measures can be utilised within cancer treatment, specifically the assessment of cancer-related cachexia and improving the accuracy of body measures used in chemotherapy dose prescription. I am currently completing an Early Career Research and Innovation Fellowship, further developing this research area of advanced body measurement within anti-cancer treatment.
