The greatest grand challenge for any scientist is discovering how to prevent the spread of HIV and finding the cure or an effective vaccine for AIDS.

I wanted to become a mathematician, physicist or astronomer.

During the week that I arrived in the United States, I saw an airport, used a telephone, used a library, talked with a scientist, and was shown a computer for the first time in my life.

Because I believe that humans are computers, I conjectured that computers, like people, can have left- and right-handed versions.

Scientists try to discover or unravel the mysteries of nature. Some of the problems we are trying to solve have been solved in nature.

Because I am not formally trained in the medical sciences, I can bring in new ideas to AIDS research and the cross-fertilization of ideas from different fields could be a valuable contribution to finding the cure for AIDS.

When I enrolled in college at age 19, I had a total of eight years of formal classroom education. As a result, I was not comfortable with formal lectures and receiving regular homework assignments.
