I am an educator and neuroscientist who studies how the brain learns to read and what happens when a young brain can't learn to read easily, as in the childhood learning challenge, developmental dyslexia.

The act of learning to read added an entirely new circuit to our hominid brain's repertoire. The long developmental process of learning to read deeply changed the very structure of that circuit's connections, which rewired the brain, which transformed the nature of human thought.

There's an old rule in neuroscience that does not alter with age: use it or lose it. It is a very hopeful principle when applied to critical thought in the reading brain because it implies choice.

Deep reading refers to a whole continuum of processes that include some of the most important things about thinking and how we connect thought to what we read - critical analysis, analogical reasoning, how we infer from the text, how do we take another's perspective.

I think the combination of graduate education in a field like Computer Science and the opportunity to apply this in a work environment like Microsoft is what drove me. The impact these opportunities create can lead to work that has broad, worldwide impact.

I believe this system of mass incarceration would have Dr. King turning in his grave. There's no doubt in my mind that Dr. King would be doing everything in his power to build a movement to end mass incarceration in the United States; a movement for education, not incarceration.

A self-defined challenge is an irresistible teacher.

But if we learn to think of it as anticipation, as learning, as growing, if we think of the time we spend waiting for the big things of life as an opportunity instead of a passing of time, what wonderful horizons open out!
