Dr Michael Thrippleton (PhD)

Research Fellow, HCPC-registered Clinical Scientist


Michael Thrippleton is a Research Fellow and registered Clinical Scientist. He trained at Cambridge and MIT, and joined the Brain Research Imaging Centre as its Medical Physicist in 2012. Having helped to establish the Edinburgh Imaging Facility RIE, he now leads and supports magnetic resonance imaging (MRI) in a large number of clinical research studies. 

Techniques: DCE-MRI, quantitative MRI, cerebrovascular reactivity, blood flow, MR spectroscopy

Disease areas: small vessel disease, neonatal, multiple sclerosis, reproductive, healthy physiology
