Dr. Kalia is a professor in the Department of Medicine at the University of Toronto and a clinician scientist at Toronto Western Hospital.



Dr. Kalia completed her combined MD/PhD training at the University of Toronto. Her doctoral research was performed under the supervision of Dr. Michael Salter at the Hospital for Sick Children. She pursued residency training in neurology at the University of Toronto and postdoctoral research at the MassGeneral Institute for Neurodegenerative Disease at Harvard University with Dr. Pamela McLean. Dr. Kalia returned to Toronto to continue her training as a movement disorders fellow at the Toronto Western Hospital with Dr. Anthony Lang.

Dr. Kalia is an assistant professor in the Division of Neurology, Department of Medicine at the University of Toronto. She is a clinician scientist at the Toronto Western Hospital, University Health Network with appointments at the Krembil Research Institute (Krembil), Tanz Centre for Research in Neurodegenerative Diseases, and Department of Laboratory Medicine and Pathobiology.

Her research program focuses on Parkinson’s disease and aims to understand the key molecular pathways responsible for neurodegeneration to develop novel therapies. Her lab uses a comprehensive approach involving molecular biology techniques, in vitro biochemical assays, cellular models, and in vivo animal models. Her clinical practice is dedicated to the care of patients with Parkinson’s disease and related disorders. Thus she is in an ideal position: 1) to utilize observations made in the clinic to generate hypotheses that can be tested in the lab; and, 2) to translate lab discoveries to have positive impacts on the lives of patients with neurodegenerative disorders.

Disease-modifying strategies for Parkinson's disease Movement Disorders : Official Journal of the Movement Disorder Society


In this review, we summarize the clinical trials of disease-modifying therapies for PD that were published since 2013 as well as clinical trials currently in progress. We also discuss promising approaches and ongoing challenges in this area of PD research.

α-Synuclein and Lewy pathology in Parkinson's disease Current Opinion in Neurology


The role of protein aggregates, such as Lewy body inclusions, in the molecular pathogenesis of Parkinson's disease has remained controversial and elusive. The protein α-synuclein is a major component of these inclusions but it can exist in many alternate conformations. Here we review advances in our understanding of the roles of Lewy pathology and α-synuclein in Parkinson's disease.

Clinical correlations with Lewy body pathology in LRRK2-related Parkinson disease JAMA Neurology


Mutations in leucine-rich repeat kinase 2 (LRRK2) are the most common cause of genetic Parkinson disease (PD) known to date. The clinical features of manifesting LRRK2 mutation carriers are generally indistinguishable from those of patients with sporadic PD. However, some PD cases associated with LRRK2 mutations lack Lewy bodies (LBs), a neuropathological hallmark of PD. We investigated whether the presence or absence of LBs correlates with different clinical features in LRRK2-related PD.

Unbiased screen for interactors of leucine-rich repeat kinase 2 supports a common pathway for sporadic and familial Parkinson disease Proceedings of the National Academy of Sciences of the United States of America


Mutations in leucine-rich repeat kinase 2 (LRRK2) cause inherited Parkinson disease (PD), and common variants around LRRK2 are a risk factor for sporadic PD. Using protein-protein interaction arrays, we identified BCL2-associated athanogene 5, Rab7L1 (RAB7, member RAS oncogene family-like 1), and Cyclin-G-associated kinase as binding partners of LRRK2.
