Functional Genetics of Neurodegeneration and Neurological Disorders Working Group

The Functional Genetics of Neurodegeneration and Neurological Disorders Working Group is recruiting for the next possible date

2 Master students (f/m/x)

Applications for PhD positions and postdoctoral positions are always welcome!

The Functional Genetics of Neurodegeneration and Neurological Disorders working group, led by Dr. Hans Zempel, PhD, is researching the pathological mechanisms of neurodegenerative and rare genetic neurological diseases. We are working to identify and characterize the factors that influence neuron and synaptic function. Rare genetic diseases often provide information on the development and treatment of age-related diseases, including those of a non-genetic nature - such as Alzheimer’s type dementia.

With the additional support of the CMMC, we use state-of-the-art microscopy, cell biology, genetic and biochemical methods to identify and characterize genetic and non-genetic factors of neurodegeneration of the central and peripheral nervous system.

Our research focuses on the cellular and molecular mechanisms and therapy of

  • Alzheimer’s type dementia and applied related tauopathies, such as Frontotemporal dementias (Pick's disease, corticobasal degeneration, progressive supranuclear paralysis)
  • Mitochondriopathies, such as polymerase gamma mutations
  • Neurological diseases caused by cytoskeletal disorders, cellular transport disorders or neuronal migration disorders (hereditary spastic paraplegia (HSP), lissencephalopathies)
  • 2-hydroxyglutarate aciduria and related syndromes
  • Lysosomal storage disorders
  • Neuronal cell polarity

We welcome initiatives for scientific collaboration and ideas for the treatment of neurodegenerative diseases.
