Neurobiology Research Group

The Neurobiology Research Group seeks to unravel the mechanisms of cognitive functions, from attention and behavior to memory and executive control. We are interested in cognitive dysfunction in a broad spectrum of neurological, neurodevelopment and psychiatric disorders and aims to study various aspects of neurodegeneration, using a multidisciplinary approach form behavioral studies to advanced molecular biology techniques.

Dr. Saadia Zahid’s (Neurobiology Research Group)

The brain is the essence of our minds that makes us human while governing and maintaining cellular and molecular mechanisms required for a healthy body. The aim of our research is to understand the various underlying mechanisms in Alzheimer’s disease (AD) through advance molecular approaches. The lab is extensively involved in exploring the molecular basis of neurodegenerative disorders with a focus on neuronal damage, cellular aging and various post translational modifications (PTMs) using both in vivo and in vitro systems with a variety of techniques including neuroscience, structural biology, novel proteomics and genomics technologies. We are also curious to unravel the molecular association between metabolic disorders with AD by studying effects of synthetic antidiabetic drugs. The researchers at our lab are also involved in investigating various natural products of therapeutic potential which offers an excellent approach to identify novel agents to treat AD and its associated disorders. The lab successfully established the role of various natural compounds as active psychostimulant and anti-anxiety and depressant agents. In addition, involvement of various PTMs in glioblastoma multiforme is another exciting research target of our lab. We at NBL are determined to find novel drug candidates to develop better therapeutic strategy for combating AD and other neurological aberrations by employing both wet lab and Insilico approaches.

Focus of the Laboratory:

  • AD as a metabolic disorder: a new paradigm
  • Proteomics and Genomics of AD
  • Post-translational modifications in AD and brain tumor.
  • Proteins as drug targets for AD
  • Phytochemicals of therapeutic potential for AD
