Laboratory Focus

Our laboratory primarily focuses on environmental and occupational risk factors in neurodegeneration, specifically neurotoxicants related to parkinsonism and cognitive impairment. We have recruited a large cohort of individuals with occupational and environmental manganese exposure both domestically and in South Africa. These complex projects include coordination of longitudinal exposure assessments, cognitive and motor phenotyping, magnetic resonance imaging (MRI), and multi-ligand positron emission tomography (PET) imaging, and biofluid specimen collection. 

We are also interested in prodromal states in neurodegenerative conditions and have multiple projects focused on MRI, single photon emission computed tomography (SPECT), and PET imaging phenotypes in prodromal synucleinopathy (RBD) and more recently long covid as a potential risk factor for Alzheimer’s disease (AD).
