About HanBang

Hi My name is Sang K. Han. I used to be a neuroscientist with a longstanding research interest in the somatosensory system, particularly my studies focused on defining neurocircuitry of pain and itch pathways.

A culmination of study in science and traditional oriental medicine has given me a unique understanding of the human body, allowing me a creative approach in dealing with malfunction of human body.
