Research Interest

1.1 Neurogenesis in the adult and developing brain.

I focus on new neurons that are continually generated throughout adulthood in predominantly two regions of the brain, especially, the subgranular zone (SGZ) of the dentate gyrus in the hippocampus.

1.2 Application of bioactive compounds from Thai plants in biomedical research.

I am interested in the antioxidant effect of Thai plants on neural stem cells in the hippocampal dentate gyrus that is associated with memory, anti-aging and anti-cancer.
