Varun's post-doctoral research (funded by NIHR-BRC) focuses on examining myelin differences underpinning learning and working memory difficulties in children with Neurofibromatosis type-I (NF1), as well as its phenotypic relationship with Autism Spectrum Conditions. To understand the myelin neurobiology in NF1, we use quantitative MRI techniques including Magnetisation Transfer Ratio and T1W/T2W ratio to assess the grey and white matter myelin.
