Our lab studies neurocognitive aging in nonhuman primate models, in the context of typical and pathological aging as well as menopause. 

Current Research
The marmoset is a small nonhuman primate that is increasingly used in neuroscience research due to its close resemblance to humans in many aspects of physiology, brain organization and behavior. Due to a short lifespan of about 12 years, the marmoset is uniquely suited for aging studies.  Three main projects focusing on marmoset neurocognitive aging are ongoing (1) A longitudinal study seeks to identify the biological correlates of sex differences in cognitive and brain aging, using behavioral, physiological, neuroimaging and neurohistological techniques; (2) In a second project, we are developing a marmoset model for menopausal symptoms in order to understand potential interactions between cognitive deficits, sleep disturbances and thermoregulation impairments that are associated with estrogen loss; (3) Recent studies examine the aged marmoset as a model for preclinical Alzheimer's disease, in order to identify behavioral predictors of neuropathology.
