Larry

I like to do math research with people. My other hobbies include painting and practicing Kung Fu. I have painted Euler and Archimedes in oil paint. My Kung Fu sensei teaches 7-star Praying Mantis. Every summer I would go back to China to practice Kung Fu. Wish I could get a Ph.D in pure math in the future.
