The research mission of Lin Brain Lab focuses on exploring nutritional and pharmacological interventions to decelerate brain aging, enhance recovery from stroke and traumatic brain injury, and minimize the risk of Alzheimer’s disease (AD), the predominant form of dementia. Leveraging advanced tools like neuroimaging, gut microbiome sequencing, transcriptomics, proteomics, and artificial intelligence, the lab intricately investigates the multifaceted nature of neurodegeneration. The future vision is to cultivate precision medicine and individualized nutritional strategies, specifically aimed at underlying genetic elements such as the APOE4 gene. We anticipate that these endeavors will lay the groundwork for a future in which brain aging, brain injury, and AD are not merely subjects of study but conditions effectively countered through tailored and precise interventions.
