Postdoctoral fellow_Johns Hopkins School of MedicinePosted by: Johns Hopkins School of Medicine
Posted date: Jun-07-2018
Location: Baltimore, MD
Employer: Department of Neurology, Institute for Cell Engineering, Johns Hopkins School of Medicine
Location: Baltimore, MD21205, USA
Type: Postdoctoral Fellow
Position Overview: Two postdoctoral fellow positions are immediately available in the laboratory of Dr. Han Seok Ko in the NeuroRegeneration and Stem Cell Programs, Institute for Cell Engineering, Department of Neurology, Johns Hopkins University School of Medicine. There are ample opportunities to interact and collaborate with other scientist at NeuroICE (http://www.hopkins-ice.org/neuro/int/faculty.html ) and the School of Medicine.
Lab introduction: The overarching goal of my scientific work has been to define key molecular pathways in the pathogenesis of Parkinson’s disease (PD) and to identify novel targets for therapeutic development. Our lab is focused on pathways that are critical for understanding the neurodegenerative process as follows:
1. Mechanisms that initiate and govern the conformational conversion of soluble α-synuclein proteins into insoluble amyloid fibrils.
2. Mechanism that underlies gut to brain transmission of pathological α-synuclein and development of the gut-brain α-synuclein transmission mouse model.
3. The downstream neurotoxic effects of aggregated α-synuclein proteins with emphasis on oxidative stress, mitochondrial dysfunction, and the autophagic / lysosomal degradation system.
4. Defining the role and molecular characteristics of neuroinflammation in PD.
5. How dysfunction of mutated GBA1 leads to PD or how GBA1 becomes dysfunctional in the absence of mutations in sporadic PD.
