Biography

Geraldine is a graduate of University College Cork where she obtained her B.A. (Hons) and Ph.D. in Psychology.  Geraldine is a Senior Lecturer in the School of Psychology and in this role established Ireland first M.Sc. in Applied Behaviour Analysis in 2006. Over 180 students have graduated from this programme and are employed in a range of autism services. The M.Sc. programme is ranked 3rd in the World in respect to the pass rate of the Board Certified Behaviour Analyst (BACB) exam, which graduates sit to become certified practitioners.   

Geraldine’s research interests lie in area of autism spectrum disorder (ASD), rare and related neurodevelopmental conditions and intellectual disability (ID).  She is especially interested in the study of comorbid conditions and how they affect the diagnosis of ASD.  She also conducts interdisciplinary research primarily concerned with improving the quality of life of individuals with a diagnosis of ASD and with ID. Geraldine is the founding Director of the Irish Centre for Autism and Neurodevelopmental Research (ICAN) which she established in 2012. ICAN is made up of Principal Investigators and Post-Doctoral researchers who are implementing cutting edge, inter-disciplinary research based on identified priority research areas including biological research, environmental risk factors, behavioural research, co-occurring conditions, employment and assistive technology.   

Geraldine was appointed Director of Research of DOCTRID (Daughters of Charity Technology and Research into Disability), an international research institute established by the Daughters of Charity to conduct service based research into ASD and ID in 2017.  Through Geraldine’s leadership, Doctrid has embarked on an ambitious research agenda which has included supporting and empowering people with ID to access education, employment, community participation, and independent living.  She is a PI in the Assistive Technologies in ASD and ID (ASSISTID), an EU FP7 €8.8m award (2014-2019). She is a PI in GEMMA (Genome, Environment, Microbiome, and Metabolome in Autism) which was recently awarded €14.2 million from Horizon 2020 (2019-2024).  To date, Geraldine’s research has attracted €3.5 million from Horizon 2020.  

Research Interests

Geraldine’s research interests lie in area of autism spectrum disorder, rare neurodevelopmental conditions and intellectual disability.  Geraldine conducts research into the epidemiology, assessment and treatment of autism spectrum disorder.  She is especially interested in the study comorbid conditions and how they affect the primary diagnosis of autism spectrum disorder.  She also conducts interdisciplinary research primarily concerned with improving the quality of life of individuals with a diagnosis of autism spectrum and with an intellectual disability.

Teaching Interests

I established Ireland’s first MSc programme in Applied Behaviour Analysis in 2006. The programme provides professional-level education in the field of applied behaviour analysis to practitioners and researchers seeking careers in the area of autism spectrum disorder and other disabilities. To date 120 students have graduated from this programme and are employed in a range services. The programme is accredited by the internationally recognised Behaviour Analyst Certification Board (BACB®). My teaching interests lie in the areas of Applied Behaviour Analysis and Autism Spectrum Disorder.
