Research Interests:

Dr. Faden's research focuses on mechanisms and modulation of cell death and neuroinflammation after experimental brain or spinal cord injury, including molecular and cell biology, animal modeling, behavior and drug discovery. The program is highly interdisciplinary, utilizing molecular and cellular biology, biochemistry, electrophysiology, pharmacology, behavior, magnetic resonance imaging and spectroscopy, and quantitative histological analysis.

There are 4 major lines of investigation:

  1. examining mechanisms of cell death in CNS injury, using both in vivo and in vitro models with particular emphasis on caspase-dependent versus caspase-independent programmed cell-death;
  2. elucidating the role of metabotropic glutamate receptors (mGluR) in posttraumatic cell death and microglial modulation, and delineating the signal transduction pathways involved;
  3. investigating the role of cell cycle pathways in the pathobiology of traumatic brain and spinal cord injury; and
  4. developing novel neuroprotective treatment strategies, with particular focus on multifunctional targeting.
