  • Daniel El Kodsi, PhD

    During Daniel's scientific training as a neuroscientist, under Dr. Michael Schlossmacher, he focused on the pathogenesis of early-onset parkinsonism. He was able to: (i) investigate the PD pathogenesis and delineate disease mechanisms; (ii) build animal models to restage PD gene-linked neural degeneration; and (i) delineate Parkin-related cellular mechanisms using both cell and protein modelling. These efforts culminated in the discovery of a novel antioxidant function for wild-type parkin in human brain. Transitioning into more clinical work, he focused on COVID-19 research, sero-surveillance and prevalence, under the supervision of Dr. Amy Hsu. As a clinical research program manager he was tasked with: (i) assessing SARS-CoV-2 infection, re-infection, and serious outcomes in Long-Term Care (LTC) sector; (ii) investigating natural and vaccine-induced immunity; and (iii) building prediction models for SARS-CoV-2. This allowed him to harness high-level project management skills.

  • Zane Jaunmuktane, MD

    Zane Jaunmuktane is a Clinical Lecturer and Honorary Consultant Neuropathologist at the Queen Square Brain Bank for Neurological Disorders and in the Division of Neuropathology, Department of Clinical and Movement Neurosciences, University College London. Together with colleagues, she was the first to demonstrate that under certain circumstances, amyloid-beta pathology is transmissible in humans. Zane's main interest is in the cell-to-cell spreading and regional propagation mechanisms of misfolded proteins and how concomitant pathologies determine disease progression and symptom severity.

  • Alexandra Nelson, MD, PhD

    Alexandra Nelson, MD, PhD, is a systems neuroscientist and movement disorders neurologist. Her research is focused on the cellular and circuit bases of motor control, and in particular how these go awry in the context of movement disorders, such as Parkinson’s disease and dyskinesias. She is known for her expertise in ex vivo (slice) and in vivo electrophysiology, as well as her use of optogenetics and other cell type-specific tools. She has made contributions to our understanding of the cellular and circuit mechanisms of motor learning, as well as the function of basal ganglia microcircuits. In the context of disease, her laboratory has identified key basal ganglia physiological correlates of disease symptoms and effective therapies (such as dopamine replacement therapy and deep brain stimulation) in mouse models of Parkinson’s disease.

  • Weiyi Peng, PhD

    Dr. Peng is an Assistant Professor in the Department of Biology and Biochemistry at the University of Houston (UH). She received her PhD in Baylor College of Medicine, Houston, TX in Immunology.

  • Saadia Rahman, MSc

    Saadia stared her academic career studying the molecular genetics of cancer at Brunel University, UK, which she took to Masters level also at Brunel. She worked in the field for a short time before switching to clinical research in 2010. She stayed on this track, consequently migrating to academic and clinical research management. She went onto further her skills and experience taking on projects and programmes of work in drug development, research operations and now to a larger project management role.

  • James Surmeier, PhD

    D. James Surmeier, PhD, is the Nathan Smith Davis Professor and Chair of the Department of Neuroscience at the Feinberg School of Medicine at Northwestern University. He studied mathematics as an undergraduate at the University of Idaho and received his PhD in Physiology and Biophysics at the University of Washington. He pioneered the use of advanced electrophysiological, optical, and molecular approaches to unravel the roles of dopamine and acetylcholine in modulating the striatal circuitry implicated in Parkinson’s disease. These studies have yielded fundamental insights into how striatal circuits adapt to the disease and how they contribute to side-effects of symptomatic treatment. In addition, Dr. Surmeier’s group has made a significant contribution to our understanding of how the physiology of dopaminergic neurons leads to the mitochondrial oxidant stress implicated in Parkinson’s disease pathogenesis. These studies have served as a foundation for large-scale clinical trials aimed at slowing Parkinson’s disease progression.

  • Julianna Tomlinson, PhD

    Upon completion of her PhD in Biochemistry (uOttawa), Julianna joined Dr. Michael Schlossmacher’s team to focus on PD related topics. She has created a mouse model to study the interaction between mutant Gba1 and SNCA in vivo (manuscript is in preparation). In parallel efforts, Julianna and colleagues refined a method for the visualization of the olfactory system in mice. This publication highlights the abundance of a-synuclein within the olfactory epithelium and also showed that Snca protects mice against nasal inoculation with a neurotropic virus and lessens the bacterial load in sepsis (Tomlinson et al., JNT 2017). Julianna has been supported as co-PI on grants from the MJFF, Weston Brain Institute and the Canadian Institute of Health Research. In her current role as Sr. Research Associate and Scientific Project Manager in the Schlossmacher team, she contributes to project conception, design and implementation, to overseeing graduate students and is leading scientific projects.

  • Laura Volpicelli-Daley, PhD

    "While working as a senior scientist in the lab of Drs. Virginia Lee and John Trojanowski at the University of Pennsylvania, Dr. Volpicelli-Daley discovered that fibrils of α-synuclein act as seeds to template the growth of α-synuclein inclusions from endogenously expressed α-synuclein in neurons. These inclusions are remarkably similar morphologically and biochemically to those found in PD. Importantly, she showed the fibrils do not cause phenotypes in neurons lacking endogenous α-synuclein, demonstrating that corruption of normal α-synuclein contributes to neuronal defects. Currently, her lab focuses on the impact of pathologic α-synuclein on synapse architecture and function in the cortex and limbic brain regions. In addition, the lab studies how accumulation of glycosphingolipids in the brain causes neuronal dysfunction, synapse loss, and cognitive decline in PD.
