I will never forget my experience of working alongside doctors to fight against the horrible disease, SARS, in China in 2003. This work taught me the great impact of disease control and prevention and motivated me to apply for the biostatistics program at Yale University, with the ultimate career goal of becoming an influential professional or_ researcher in the field. I firmly believe that my constant thirst for knowledge, high regard for the work in the biomedical and public health fields, and my courageousness will drive my graduate studies and help me achieve personal and professional success.

　　I first became interested in biostatistics when the SARS epidemic breakout in China in 2003. As a member of the University Red Cross Association, I was responsible for assisting the university hospital to publicize disease prevention methods, distribute medicine, and complete health surveys. I learned from that process the value of survey dates in supplying useful strategies for disease prediction, prevention and control. Afterward, when I served as Vice President of the Student Union, I organized an introductory lecture and health survey about hereditary disease for the local community. I truly enjoyed these voluntary public health services, as I was able to use my knowledge to enhance the quality of life for my fellow man. These achievements gave me the determination to fully devote myself to public health services and global health care development.

　　My academic training to this point has provided me with a wide range of general knowledge and skills related to the biological sciences. This training is an excellent first step in preparing for the professional career that I desire. As an undergraduate student in bioengineering at XX University, I acquired a solid foundation in the theoretical concepts associated with genetics, molecular biology, immunology, and biochemistry. I also gained knowledge in the several areas of industrial significance, including bio-products, fermentation, and biotechnology. In addition to the comprehensive studies in my major field, I received as well extensive training in mathematics and computer science, both of which were of great benefit to my study of biostatistics, an important area in various industrial and scientific research efforts. For example, as I learned during my summer internship as an Assistant Researcher at the XX Pharmaceutical Company in 200X, biostatistics has a vital role in the development and marketing of new medicines, in the control of the quality of products, and in the tracking of consumer trends, attitudes and purchases. I have also worked as an undergraduate research assistant for a map-based cloning project in the XX Biology Center, where I used statistical methods to develop WW genetic markers and to calculate the probabilities of recombination. These hands-on training activities gave me a clearer understanding of and a deeper insight into the biostatistics of biological and clinical problems.

　　I look forward to furthering my knowledge of biostatics at Yale University. Indeed, I believe that Yale’s dynamic environment coupled with the emphasis placed on both statistics theory and real-life biological issues in the biostatics program will prepare me well to stand out in future competition. Therefore, my well considered decision to choose your program will certainly help me realize my dreams. I am confident that with Yale’s beneficial guidance and training, I will be well on the way to becoming a noted professional in the area of public health.
