Statement of purpose

When I was about fourteen, my mother bought me a fancy bicycle. And from that day on, every night after finishing my homework, I always fetched a little bench sitting next to my bicycle. And used all the tools I can find at home, such as wrenches, hammers and lubricant, to do some “experiments”. I adjusted the gap between wheel and friction disk, added lubricant on the gear system and improved the comfort of gear shifting. If the outcome failed to satisfy me on the next day, the “experiments” had to be repeated. In retrospect, it is obvious that my strong interest in doing work related to mechanic was developed from that period and my persistence was trained by that educational “experiments” as well.

In 2011, I graduated from XXX Foreign Language School and was admitted to the department of Power and Energy Engineering in XXX University of Technology, which ranks top among engineering programs in China. In the first academic year, due to much focus on student activities and various contests, I didn’t pay enough attention to academic study, I ranked only 13 in my class. Motivated by the shame and my eager to excellence, I poured huge endeavor into my academic study in the second academic year, and reaped what I sowed. I ranked among the top 10% in my department.

During the undergraduate study in my campus, I constantly strived to improve myself, and kept a good GPA of 3.65 (5.0). I have taken the class named Principle of Internal Combustion Engine, in which I got the basic understanding of engines with steps and dominant emphasis; from the class Signal Analyzing and Processing, I learnt to show a working condition graphically and from the class the Emission and Control of Internal Combustion Engine, I come to realize the vitality and difficulty of low emission of engine. Besides taking classes in classroom, I have devoted to myriad experiments and course designs, I have designed a gear box and heat transfer independently, I tested the load and velocity characteristic of a two cylinder diesel. And in a semi-noise reduction lab, I managed to analyze the working condition of a diesel with numerous data detected by various sensors. Taking such specialized engineering course have definitely provided me with a solid foundation for working at the interface between theory and reality. Besides taking course required by our training plan, I also attempted to extend my scope by undertaking some extra-curriculum projects. By doing so, I wanted to establish a more comprehensive perception of how the theoretical knowledge could be applied to practical uses.

While class learning equipped me with basic theoretical knowledge, project experience led me on the road to academic maturity. In the second academic year, I started a project with four other fellows under the guide of professor Yang (one of my referees). We devised a three way valve triggered by human’s infrared signal detected by infrared sensor. And it is controlled by two time relays, used to maximize the efficiency of the system. We spent most of a summer vocation buying electric parts, inevitable tools and another 3 months assembling various parts together in the electric lab. Through wiring, welding, and testing all by ourselves, the whole system was functional as we expected. And it won a second prize in our campus science competition. From that experience, I understand the importance of team cooperation and persistence towards goal. Meanwhile at that time, I managed to apply for professor Lv’s lab (one of my referees) for further enlargement of my horizon. I have observed how master and doctoral students do their experiment on diesel engine (such as ETC testing and so on), and how they attended to problem that emerged unexpected. No matter how heavy my academic work at that time, whenever they had a discussion meeting, I would always join their discussion in purpose of new knowledge.

One of my challenges come in the third year. I cooperated with friends from the department of Computer and Science on a project on image procession funded by The National Natural Science Fund. It was really a challenge for me. I accepted it and thus get a deeper understanding of image and signal procession. Based on the technology of image processing, we proposed a new method to count cells on the image of microscopic cells with high level of recognition. To precisely count the number, our method included edge detecting and marking, efficient usage of three channel information of enhanced nucleus, binaryzation of dynamic threshold in separated areas and finally denoising. The experiment showed that our method was precise and quickly-reacted, moreover it could effectively rule out the impact of impurities. And with little adjustment, it could be applied to other fields, not only decrease the labor involved, but the budget as well. What’s more, we managed to publish our paper in Applied Mechanics and Materials, which meant my dream was thriving towards sunshine.

Looking back, I’ve already dealt with a range of relevant issues such as mechanical vibration, image and signal procession, and have got familiar with a number of experiment techniques towards internal combustion engine. These research experiences have opened a door towards the scientific world of engineering for me. Looking forward, I will definitely devote myself to this area and hope to make a contribution to a variety of essential issues.

My current interests lies in mechanical engineering but not limited to. I am now engaged in my internship (next semester the internship begin). By my scrutiny of your departmental website, I am glad to know that you place great pride in your interdisciplinary work ethic and provide a variety of resources, especially advanced engine lab and E3 lab, which not only matches my academic background, but also aligns well with my interest and passion. In addition, it has a promising future and I really expect to contribute to this area. Therefore, I’m eager to be a part of your program, since the interdisciplinary training and strong academic atmosphere will certainly help me become a successful researcher to make discoveries in this field.

Others judge me by what I’ve done, but I hope you judge me by what I am capable doing. I have overcome challenges over and over again when others don’t think I can. I am positive that the graduate training from your program can equip me with great insights and strong expertise, and TAMU will definitely be the place where I can realize my dream.
