About the lab
The overarching goal of our research is to better understand the psychological processes that underlie a range of clinically relevant behaviours. Rather than classifying individuals based on collections of overt symptoms, we focus on endophenotypes – neurocognitive processes associated with discrete deficits in defined neural systems. For example, individual differences in inhibitory control have been shown to be a feature of ADHD and of addictive behaviours. In order to study these endophenotypes, we employ non-invasive methods of measuring brain function in vivo, including magnetic resonance imaging, high-density electroencephalography, and behavioural assays of neurocognitive functioning (we have also started to collect the latter using online methods). Our research sometimes includes an intervention, such as neurofeedback or using an eHealth platform. We often then use machine learning to integrate these brain measures with genetic data, information on social relationships and on life history to build a more complete picture of the influences on behaviour. Ultimately, we hope our research will result in better treatments, either psychological and/or pharmacological, for individuals.
There are three streams of research in this lab: Addiction, ADHD, and Methods. Addiction investigates the changes in brain, and behaviour due to smoking, alcohol, and cannabis use. ADHD examines the neurocognitive profile, genetics, and anxiety of the disorder. Methods focus on computational modelling, and machine learning in terms of EEG and MRI.
