Basic research has played a key role in the evolutionary process of the human race since the dawn of history. Though it may not produce temporary profit sometime, it does bring about profound influence to our life in the long term. Obsessed in the beauty of Nature sine my childhood, I decided to devote all my energy to explore the secrets of Nature . When I was a high school student, I borrowed the book "Atoms in the Family " written by Laura Fermi. I was deeply moved by the research life of Enrico Fermi and his friends. They actively worked together with common interests, hitting on significant discoveries through mutual suggestion and stimulation. How I wish I could experience such cooperative and original life someday.

I have devoted most of my time to learn Physics, Mathematics and Biology, cultivated my intuition and imagination. Some problems were every difficult to solve, they always haunted in my mind for days, but when after unremitting thought, finally the inspiration flashed up. I felt that was one of the most exciting and joyful moment of life thought, finally the inspiration flashed up, I felt that was one of the most exciting and joyful moment of life .

My grades in the courses of Physics and Mathematics are the best in my class To facilitate further study in Physics I selected the courses "Applied Modern Algebra" focusing on the theory of group, ring, field and "The Principle of Real Analysis " concerning the Lebesgue Measure and Calculus. In the course of Lab of Modern Physics, I did many interesting experiments such as Laser Raman Spectroscopy, X-ray diffraction studies, Mossbauer effect, Optical pumping magnetic resonance. Besides, through research work after class. I learned what had not been taught before, e.g. how to model the real world, how to apply the theory to practice and got more understanding about the projects.

As a student major in Optoelectronics at the Department of Electronic Engineering, I am also versed in Electronics, Computer Science, Communication System and Laser Technology through firm and a large quantity of practical training. For example, I have made the computer simulations of electronic circuits, programmed optimum algorithm for rapid search, designed and composited a simple CPU project, In our Lab of Lasers and Optoelectronics, I completed many experiments about tunable dye lasers, static properties of solid lasers and Q-switched dyes, second harmonic lasers, holography and optical modulators. These are all useful means for basic research.

Your graduate school has the marvelous academic environment and the high quality of Ph. D. Education I have expected. I hope I could join you to learn to be an independent researcher with broad base of natural sciences. I also hope to combine the Chinese Ancient Philosophy with Modern Science in the United States. Upon completion of the study, I shall return to my motherland and further my research to do more contribution for the common benefit of society. I shall return to my motherland graduate status endowed by Tsinghua University, so if I can not get your admission. I have to study by myself while making a living.

The unforgettable song often sounds in my mind. "Climb every mountain, ford every stream, follow every rainbow till you " till you find your dream. A dream that will need all the love you can give, every day of your life for as long as you live. I am sure that someday my dream of research life will come true.
