Nan Zhang: Gossip Girl and Science Girl
Nan Zhang stars as Katy on Gossip Girl.
In real life, however, this actress stars in the science lab. She recently said:
"I studied for ophthalmology and neuroscience research, and later I focused on photoreceptor retinal damage and ear protection. So just after the [first Gossip Girl episode] wrapped, I was also working on stem cell research."
Wow. Consider us impressed.
