Research Fields

I am currently working on investigating the visual processing abilities of patients presenting with visual deficits after brain lesions, using eye-tracking glasses and behavioural approach. 

In my clinical neuropsychological practice, I am interested in investigating the cognitive and behavioural deficits among patients with brain lesions.

In the past, I focused particularly on the assessment of cognitive deficits among patients suffering from sickle cell disease (SCD). More specifically, we developed a project in collaboration with the Yaounde Central Hospital, in Cameroon, where sickle cell disease is a major public health concern. The cognitive performances of Cameroonian SCD young patients were evaluated using a neuropsychological test battery assessing four domains of cognitive functioning (executive functions, attention, memory, and sensory-motor skills) previously adapted and normalized on healthy subjects in Yaoundé. Among others, results showed that patients in Cameroon presented a very high prevalence of cognitive deficits, with a specific impairment of executive functions and attention. This project also indicated that routine neuropsychological evaluation for early detection of cognitive deficits in SCD patients could represent a cost-effective tool to implement in resource-limited contexts such as in sub-Saharan Africa.

Education 

I obtained a Bachelor of Science in Psychology at the University of Fribourg in 2002 and a Master of Science in Psychology at the University of Geneva in 2005. Between 2004 and 2006 I worked at the Geneva Hospital as a clinical neuropsychologist. Then I obtained in 2011 a PhD at the University of Geneva, with a thesis on the cognitive deficits among patients suffering from sickle cell disease (SCD). More specifically, we developed a project in collaboration with the Yaounde Central Hospital, in Cameroon. The cognitive performances of Cameroonian SCD young patients were evaluated using a neuropsychological test battery assessing four domains of cognitive functioning (executive functions, attention, memory, and sensory-motor skills) previously adapted and normalized on healthy subjects in Yaoundé. Since 2011, I work as a clinical neuropsychologist at the Fribourg Hospital (60%) and since 2013 I work in the Department of Psychology of the Fribourg University (20%), in the I(eye) and Brain Mapping Laboratory supervised by Prof R. Caldara.
