My Approach

Whenever I learn something new, I try to find its application with original ideas. In elementary school, I was interested in capillary action. I invented an applicable experimental apparatus with paper and tea, instead of glass tubes or cloths and water. The paper has cuts, and tea rises along each cut when it is soaked. I tested some paper samples in different cut intervals, and found that fine cuts (with many surfaces) can carry tea to a high level. In junior high school, I learned how to solve linear equations. I discovered that the solving process is separated into two independent procedures, transposition and four arithmetic operations. I created useful templates which calculate the solution of equations immediately after I copy the coefficients of equations into each blank of the template. In high school, I studied the equations of motion in physics. I applied the resolution of vectors, which was taught in mathematics, to force vectors. The motion is obtained systematically by solving algebraic equations for each component of force vectors. In university, I practiced the calculation of expectation values in quantum mechanics. I simplified the complicated calculation by the symbolization of creation and annihilation operators. Finally, in graduate school, I constructed coupled map lattices (CMLs) for three interdisciplinary issues, food chains, astronomical patterns, and food textures. The proposed CMLs perform fast computation, which not only reproduces the dynamic behavior of these complex systems, but also predicts a new class of dynamic behavior.

I will keep learning in any fields, and find various applications with original ideas. Persistence will pay off!

On the day I graduated with my Ph.D., under cherry blossoms in full bloom.
