For me it was this idea that there was something really important to be gained just by hanging out with the kids and getting to know them ... and for them to get to know other people who live different lives.

I got to take a lot of pictures of them hanging out and being themselves.

I got to spend a summer while in medical school not doing research, hanging out with kids and taking pictures -- something I didn't get to do while I was studying.

It's really hard to walk into any social-service agency as an outsider, especially when working with kids.

The whole idea of developing the implant is to provide a consistent delivery of medication that can quiet down the inflammation within the eye without causing side-effects elsewhere in the body. We can potentially then get people off all the other medications they have needed for years, many of which cause significant side-effects and are uncomfortable, making the patient fairly miserable.

'Friday' is about hanging out with friends, having fun. I felt like it was my personality in that song.
