I'm just a regular guy. I want people to realize that I embody the true American dream. I work hard. I went to school.

Developed countries will always welcome the Einsteins of this world - those individuals whose talents are already recognized and deemed to have value. This welcome doesn't usually extend to the poor and uneducated people seeking to enter the country. But the truth, supported by the facts of history and the richness of immigrant contribution to America's distinction in the world, is that the most entrepreneurial, innovative, motivated citizen is the one who has been given an opportunity and wants to repay the debt.

To hear the amount of hate that people have in the United States is disheartening. However, I still have hope that we have not reached the pinnacle.

As a researcher at US Berkeley I used to go into the brains of small, little animals and study the way that brains were connected and how little did I know that one day that was going to be my future - exploring the universe of the brain and hold it in between my hands and look at cells migrating.

I continue to do my job as a brain surgeon, as a researcher, and I try to make it better and better every day, not only for my patients but for their families, for my family and for the future generations of our country.

If you look at some of the clips of me in the operating room, I sit in the chair, I control the microscope with my mouth, I connect, my hands are always working in the brain, my feet are controlling everything.

The same skills that I used as a welder, as a migrant farm worker, are similar skills that I'm using as a brain surgeon.
