Mark Mikkelsen


I received my BSc degree in psychology at the University of Glasgow after which I attended Bangor University for my MSc in neuroimaging under the supervision of Dr Paul Mullins. I later obtained my PhD at the Cardiff University Brain Research Imaging Centre (CUBRIC) where I was supervised by Prof Krish Singh, Prof Petroc Sumner and Dr John Evans. My doctoral thesis centred on the MRS of GABA, specifically its methodological development and multimodal application alongside fMRI techniques.

After Cardiff, I worked as a postdoctoral researcher in Prof Narender Ramnani's lab in the Department of Psychology at Royal Holloway, University of London. There I investigated the role of the cerebellum in associative learning using ultra-high field 7T event-related fMRI in collaboration with the Oxford Centre for Functional MRI of the Brain (FMRIB). 

I now work in Richard Edden's lab at the Johns Hopkins University School of Medicine. As part of my research here, I develop and optimise advanced GABA-edited MRS acquisition techniques in addition to data processing and quantification methods. I also work with Nick Puts investigating the role of GABAergic inhibition in sensory abnormalities in neurodevelopmental disorders such as autism spectrum disorder and Tourette syndrome. To understand the link between these abnormalities and GABA, I use MRS, transcranial magnetic stimulation (TMS) and psychophysical approaches.
