Résumé

Geneticist's personal drive

Yuancheng (Ryan) Lu, a 34-year-old geneticist, is motivated by both his family history and personal risk factors to study age-related vision loss.

His great-aunt in China died after being unable to see oncoming traffic, and Lu himself carries a genetic mutation linked to macular degeneration, a leading cause of blindness in older adults.

Sunlight exposure is another risk factor for this condition, which is why he wears darkening aviator glasses that adjust to brightness automatically.

Lu works at the Whitehead Institute in Cambridge, Massachusetts, where he focuses on developing gene therapies to prevent or reverse age-related vision loss.

His personal connection to the issue drives his scientific research, which aims to address a critical health concern with potential life-changing implications.
