In his university life, he has studied computer science courses and been to University of California, Berkeley to advance the knowledge in technology. Having served 3 years as a data cientsit in CUHK, he has codeveloped a digital screening tool for dementia, a type of cognitive disorder with applied machine learning and cloud computing techniques. Users only need to draw a simple figure just in 30 seconds to know their dementia risk. The invention is capable of analysing real-time drawing behavioural change precise to pixel level which indicates corresponding brain activities. Non-provisional patent has been filed in the USA and China for the technology.
