Research Interests

My research focus is on neurobiology study of affecting brain cells both in vitro and in vivo upon the progression of neurodegenerative diseases. I also experienced in development of novel non-viral/antibody based technology for drug and gene delivery into the brain. At Chulabhorn Research Institute, my main research aim is to investigate neuroprotective effects of Thai medicinal plants on acute and chronic brain disorders. Long-term damage of brain cells would possibly lead to the development of neurodegenerative diseases such as stroke, Alzheimer’s and Parkinson’s diseases. An expected outcome to pursue this aim is for the further development of alternative therapy of active compounds deriving from readily available Thai plants.
