"Successful people are not gifted; they just work hard, then succeed on purpose." -- G. K. Nielson
"If we knew what it was we were doing, it would not be called research, would it?" -- Albert Einstein
"If I had an hour to solve a problem I'd spend 55 minutes thinking about the problem and 5 minutes thinking about solutions." -- Albert Einstein
"The three great essentials to achieve anything worthwhile are, first, hard work; second, stick-to-itiveness; third, common sense." -- Thomas A. Edison
"It's simply a matter of doing what you do best and not worrying about what the other fellow is going to do." -- John R. Amos
For prospective students:
I mainly work with PhD students.
While working with me, I expect that research should be a student's primary intellectual activity.
