Associate Research Fellow
I’m a developmental neuroscientist who moved to the CBCD to study for a PhD researching the associations of early life visual experiences (i.e. daily use of touchscreens devices, like tablets and smartphones) on the development of visual attention and executive function, under the supervision of Dr. Tim J. Smith and Dr. Rachael Bedford. During my studies I was part of the TABLET Project team, and I was very happy to be involved in their public engagement activities on the topic of toddlers and touchscreens throughout my studies.
Recently, I moved to the Center of Neurodevelopmental Disorders at the Karolinska Institutet in Stockholm, where I am working as a postdoctoral researcher in developmental behaviour genetics in the research group headed by Dr. Terje Falck-Ytter (the DIVE lab). I’m using data collected as part of an infant twin study to understand the etiological factors behind early brain and behavioral processes, including attention and behavioural control, in collaboration with Professor Angelica Ronald (head of the GEL Lab at the CBCD).
