John has recently joined the Psychology Department on a teaching-track position for the Clinical Psychology MSc program. He completed his Doctorate of Clinical Psychology at the University of Auckland, in collaboration with Harvard University/Mass General Hospital. Prior to working at NUS, he worked conjointly as a clinical psychologist and a post-doctorate fellow in Melbourne, Australia. His clinical work has primarily been with adults and older adults, both in mental health and neuropsychological settings. His research has focused on development and implementation of neuropsychological assessments for several multi-site, international studies of Huntington’s Disease (PREDICT-HD; TRACK-HD; CAB-Beta). This has involved selecting and developing various cognitive tasks, and then using prospective, observational studies to test how sensitive these tasks are for measuring progression of the disease – from pre-symptomatic stages through to advanced stages of the disease. Tasks that show good sensitivity (and other psychometric properties, such as test-retest reliability and short duration) will be used as potential biomarkers for assessing the effectiveness of treatments for Huntington’s Disease. Whilst he currently does not have any research projects active, his research interests include: clinical and cognitive biomarkers for dementias, psychosocial changes associated with ageing and dementia, cross-cultural adaptation of therapeutic models, and clinical supervision.
Dr. O’Dhaniel Mullette-Gillman joined our department in July of 2011. His research explores the neural basis of valuation, decision-making, and executive functions through behavioral, neuroimaging, genomic, and manipulation methodologies.
He completed his PhD at Dartmouth College with Profs. Yale Cohen and Jennifer Groh in the Department of Psychological and Brain Sciences, with his thesis work examining the coordinate frame encoding of auditory and visual spatial information within the parietal cortex. Joining the field of Neuroeconomics, he took a post-doctoral position in the laboratory of Prof. Paul Glimcher at the Center for Neural Science at New York University. In this position, he investigated the role of dopamine neurons in reward processing through single-unit recordings and microstimulation. Switching to work with human participants, O’Dhaniel took a post-doctoral position within Prof. Scott Huettel’s lab at Duke University. Through multiple projects, he pursued neuroimaging, behavioral, genomic, and manipulative methodologies to explore the neural basis of human decision-making.
