"My name is Peng Si and we are now in De La Zerda Lab.
I grown up in Northeastern city in China so the name of the city is Changchun.
I love writing Chinese calligraphy.
I love play table tennis.
I am very far from my parents.
I miss them a lot.
I remember seeing in college, I watched a fantastic documentary, The Planet Earth, recorded
by BBC.
So when I watched that video I was amazed by the beauty of the nature and the mystery
of life.
I remember seeing in college also like watching science fiction movies.
When I see those scenes happening, probably that happen in the future I was, I am very,
very excited.
So what we are doing here is that we develop nanotechnology and immediate tools which enables
us and the doctors to visualize the molecular information inside a tumor.
We are able to detect those nanoparticles where they are, where they inside tumor and
which molecule they are attached to.
So that means when they use some drugs to trigger, to treat tumor, we know what's happening,
what changes in the tumor and by knowing that, the doctors actually can have a idea if they
strike, it's efficient or not.
Like the reason you're seeing that signal is because of the particles.
Like if I want to look at some cell surface receptor that's expressed by a particular
type of cancer.
Most of my grandma and the grandpa got cancer.
I mean I saw they suffer a lot of pain and although they had a happy life, in their whole
life but the last well two years they suffer.
They suffer a lot.
I was really sad about that.
When I was a young kid I cannot understand why people spend a lot of money to have those
therapies for cancer but they still cannot survive.
They cannot treat the cancer.
That's one of the thing that make me determined to go to pursue the life stance that especially
the tumor, tumor study.
I was amazed by what I am doing.
Sometimes when I play the video I made, and show the blood vessels, the nerve vessels,
I was amazed how beautiful they are, how organized the structure they are.
So here you can see the laser is pointing in this point and there's another laser that's
scanning on top and you can see as this crosser comes over those beads they are starting to
move and this is because we some gold nanoparticles on top of them.
They really look like science fiction movie.
I think that's a new phase of human beings that we can tackle this kind of disease which
has bothered people for very, very long time.
You kind of explore the mystery of life and also you will be able to test the series that
you learned in the textbook if that's correct or not.
You are learning new things every day actually.
You will be the first person to know something other people never knows.
I really want to make something impactful to the world and to change the world, to impact
the human beings."
