Erica Ranzato- About Us

Erica Ranzato is a PhD student at Institute of Education, UCL. Her research focuses on how mathematical abilities vary and develop in individuals with neurodevelopmental disorders – such as Down Syndrome, Autism Spectrum Disorders and Williams Syndrome – with a focus on primary school children.

She collaborates with different research groups such as the Child Development and Learning Difficulties lab (Dr Jo Van Herwegen, UCL) and the Mathematical Cognition group at UCL.
