What We Do

Since 2000, I have pursued work as a physician-scientist focusing on Parkinson disease (PD), Lewy body dementia (DLB) and multiple system atrophy (MSA). Since opening my new laboratory at the OHRI in 2007, my team has focused on: (i) better modeling the pathogenesis of PD and DLB in mice; (ii) understanding the functions of 4 disease-linked genes (SNCA; GBA; LRRK2; Parkin); (iii) creating new tools, including animal models, platforms and antibodies; and (iv) exploring biological markers of PD, DLB and MSA.

Meet the Schlossmacher Lab

The Schlossmacher team unites a group of trainees, research staff and collaborators from diverse scientific interests and backgrounds - including neuroscience, biochemistry, immunology, virology, animal studies and pathology. This reflects our different approaches to studying and modelling Parkinson disease variants and related dementias.
