Research Profile

I am currently accepting applications for Graduate student positions for September 2018.

Broadly speaking, my research aims to improve the early diagnosis of dementia in older adults. I am particularly interested in how to best recognize early signs of neurodegenerative disease in individuals who have complex clinical presentations, including co-morbid medical, neurological, or psychiatric conditions that may increase dementia risk. A second important area of my research involves determining the most accurate methods of assessing cognition and predicting future decline. My work is heavily based in neuropsychology, and also integrates neuroimaging and neuropathological tools to draw conclusions about progression and mechanisms of disease.
