Yao Xiao, MD
Yao is a lab enthusiast keen on scalpel-driving, code-cracking, photo-snapping, and home-decorating. When I’m not busy in the lab unraveling the mysteries of sex hormone, aging and transplant immunology, I’m either exploring new places in the real world or uncovering bugs in The Legend of Zelda: Breath of the Wild. It’s my quirky way of mixing adventure with a love for the unexpected, proving life is full of hidden quests. Join me in the lab or in Hyrule!
