Amber Ruigrok is a researcher at the Autism Research Centre, Dept of Psychiatry. Amber’s PhD research investigated how testosterone and variation in the androgen receptor may be involved in the development of sex differences in human brain white matter in the typically developing population. Based on these findings and previous work on sex differences in autism brain structure, her current research mostly focusses on sex differences in brain structure in typically developing individuals and individuals with autism. She is also interested in network organisation and how this changes across development, particularly how puberty influences brain maturation.
