Personal History Chien-hao,liu

Personal History Applying to a Ph.D. program is my short term goal and becoming an outstanding researcher and teacher is my ultimate goal. In order to fulfill my object, I have studied hard and performed very well on my academic studies and plan to continue my graduate studies at a university where I can broaden my vision and surround myself in a superb environment to do advanced research. I believe that the esteemed University of California at Berkeley is an excellent place for me to continue my graduate studies towards a Ph.D. degree. In childhood, I spent a lot of time playing LEGO and reproduce manmade elements found in the real world(excavators, airplanes, boats ,etc) or machines in the imaginary world (UFO, robots with A.I.). During playing LEGO, I learned how to achieve my goal systematically and think like an engineer. While constructing one of them, I first figured out the shape and the characteristics of it, and then thought of how to use the LEGO elements I had to built the prototype. If I didn’t have the proper pieces , I assembled two or more LEGO blocks to fit my model. From handling LEGO, I discovered the joy of making things by hand and I played appliances I could put my hands on to figure out how they work. This passion about the mechanism prompted me to choose Mechanical Engineering as my undergraduate major at National Taiwan University. My interest in pursuing my graduate studies in the United States grew even more in graduate school at National Taiwan University. From the course, Introduction to Solid State Physics, I learned how the large-scale properties of solid materials result from their atomic-scale properties such as crystallography, electromagnetism, and quantum behaviors. This new knowledge put me at awe and made me want to study further. Therefore, I choose the phonon and its application on Solidly Mounted Resonators as my research topic. I favored developing mathematical models for physical phenomena and solving them with computers. From the results of simulation, some details of phonon behavior were understood further. In order to build solid knowledge background, I took a number of classes about modern physics and electromagnetism. In the end of the second semester, I fabricated the Solidly Mounted Resonator with microfabrication technology in the Microsystems Technology Lab supervised by Prof. Yuan-Fang Chou. I believe theoretic simulation would be verified by the experiments. During graduate studies, I discovered the joy of doing research and intended to apply Ph.D. program in U.C.B. I am interested in the fields of Micro and Nano technology, Phonon and Acoustics, and Bioengineering that are promising industries in the future. Since the area of research in the Mechanical Department at U.C.B closely overlaps my own interest, I believe U.C.B is an excellent campus for

me to continue my graduate studies towards a Ph.D. degree. I look forward to join U.C.B and, after graduation, be an outstanding researcher who will improve the life quality of human beings.
