The above video shows an Interdisciplinary project to develop a nano-scavenger.

Research Areas

  • Age-related sensitivity to pesticides
  • Neuromodulation
  • Endocannabinoid signaling in neurotoxicity
  • Nanoscavengers against OP intoxication
  • Non-cholinesterase targets of anticholinesterases
  • Modulation of neurotoxicity by diet
