Statement of Purpose
Applicant: (Name of Student)
Proposed Department and Degree: Ph.D. in Computer Science
Semester and year that the student is applying for: Fall Semester, 2001
Introduction and Undergraduate Background
As an applicant to Carnegie Mellon University's doctoral program in Computer Science, I am very glad to have an opportunity in introducing my study objectives to you.
I received a B.S. degree from Yeungnam University, which is considered to be among the best engineering schools in South Korea, in February 1996. I majored in Computer Engineering. Throughout four undergraduate courses, I completed the several fundamental courses related to both software and hardware areas of research. The courses were as follows: Operating Systems, Data Structures, Numerical Analysis, Mathematics, Engineering Mathematics, Compilers, Software Engineering, Programming Languages and Practice, DBMS, System Programming and Practice, Data Communication, Digital Logic Design, Microprocessor Laboratory and VLSI System Design. Moreover, as a term project, I designed an 8-Bit microprocessor.
Work Experiences
My work experience started in 1996. I was employed at the Business Communication R&D group in Samsung Electronics company. Samsung is one of the top research & development company in several business areas in South Korea, and in the telecommunications and semiconductor sectors in the international economy. I was assigned to the Business Communication Developing team at Samsung and developed DBMS of the digital Keyphone switching system. Due to the characteristics of the Keyphone exchange system, we did not use a commercial DBMS product. I developed a DBMS product, using HP UNIX and C languages in two years and six months. The management's strategy at Samsung Electronics was in supporting wireless telecommunications technology as one of major information & communication business areas. I was selected as one of the most qualified engineers to join the Wireless Communication Development group in July 1998.
The wireless team was developing CDMA (Code Division Multiple Access) and GSM (Global System for Mobile Communications) cellular phones. I was assigned to the GSM team. My job was developing a GSM cellular phone, which used satellite communications technology. As a preceding project of developing a cellular telephone that uses satellite telecommunication technology, we developed GSM/DCS dual band cellular telephone (SGH-2200). In this project, I developed a MMI (Man Machine Interfaces) of SGH-2200 using Visual Basic for the menu frame and Borland C++ for the main modules. I also developed a GINI debugging tool that analyzed the content of signals between phone and base stations in a GSM network. Moreover, I went on business trips to Europe to test our product in the field where service providers operate GSM networks, and on these business trips, I acquired practical experience in the field.
While developing telecommunication network systems in several countries, I was strongly motivated in applying both theory and practice in research. For example, I learned about the relevant theories in university and acquired the professional and technical skills in designing and implementing products in the field. While doing so, I realized that I wanted to increase and deepen my knowledge in computer science. Therefore, I decided to leave Samsung in August 1999 and work as a researcher at the KwangJu Institute of Science and Technology (K-JIST).
Graduate Studies
In September 1999, I was enrolled in graduate courses as a full time student at K-JIST. K-JIST is a fully government supported research institute of higher education and a cutting edge of research center in South Korea. K-JIST is a leading research institute of higher education for the following reasons. The ratio of students to professors is 5:1; Graduate students are few in number and high in international academic standards Research is conducted in conjunction with industrial and governmental support and acts as a catalyst in the technology transfer process.
Since the medium of instruction at K-JIST is English, and we study with both international students and faculty, I enhanced my English writing and conversation skills. I completed both intermediate and advanced technical writing and English conversation courses. English skills specific to professional communications and science and technical subjects were acquired in
K-JIST 's English for Science and Technology (EST) language program.
My academic interests were distributed systems and mobile software agent. I completed related courses such as Advanced Discrete Mathematics, Distributed Algorithms, Distributed and Parallel Computing, Database Design, Selected Topics on Distributed Systems, Concurrent System Theory. I received both praise and strong support from my professors in these areas of research.
Research and Project Experience
My research interests are designing distributed systems and mobile software agents. For example, I was assigned to do a project in designing and implementing a mobile agent system. The project was one of the projects of KOSEF (Korea Science and Engineering Foundation) and it was entitled "X-MAS: Mobile Agent Platform for Workflow systems" (July 1998). I designed and implemented an inter-agent communication infrastructure using Java software. After that, I wrote a thesis about my research result and it was entitled "Design of Inter-Agent Communication Infrastructure for Agent-based Workflow System" (April 2000). The thesis was accepted by KIPS (Korea Information Processing Society) in a Spring Conference (April 2000) and I received the top award.
Research Interests and Specific Goal
After considering my interests and reviewing all information about departments of compute science in several universities, I decided to apply to Carnegie Mellon University's doctoral program leading to a Ph.D. degree at Carnegie Mellon University. Professor M. Satyanarayanan's current research interests and projects are very likely to meet my expectations regarding a Ph.D. research project.
My research interests are as follows:
1) Mobility and Scalability in distributed systems
2) Reliable distributed file system
3) High-performance distributed computing
As a computer engineer, I have a strong background in computer science, professional and technical skills in programming and about four year's development experiences in the field. As a researcher, I have a strong theory base in distributed systems and project experiences in design and implementation of mobile agent systems. I am familiar with all the fundamentals and practical experiences in my research field.
What I hope to gain from doctoral studies at Carnegie Mellon University is an acquisition of advanced knowledge and the ability to carry out independent research. Upon completion of my Ph.D. degree, I will seek to pursue my studies with the aim of applying my knowledge towards the solution of specific problems in the field of distributed systems at Carnegie Mellon University, or another research institute. It is my hope that my participation in relevant research projects will contribute in the development of new and signicant knowledge in the field of information and communications technology.
I appreciate your attention and consideration in reading this statement.
Sincerely yours,

I would like to build on my solid education and experience as an engineer for a Ph. D. degree in computer science at a distinguished university. I wish in particular to be trained at an advanced level in software systems, database systems, applied-AI and knowledge-based systems. My ultimate goal is to become a professor teaching computer science at a Chinese university. I believe that advanced training in a quality graduate program will help me realize my goal.
Having worked in both academia and industries, I have narrowed down my career interest to teaching and researching, although I can also appreciate the value of other types of career. I feel that, by teaching and researching at an advanced level within the context of a university, I can make the most contribution to the progress of science and technology in my country. This is because, to a large developing country like China, the propagation of scientific and technological knowledge is at least as important as the development of cutting-edge expertise. Enough people are already devoted to mastering the state-of-the -art in computer science, but not nearly enough people are prepared to spend their life training new generations to be better than they are.
As a computer professional, I am versed in a full range of computer knowledge and skills. As a graduate student, I devoted the better part of my time to doing research on data consistency, a topic that is fundamental not only to the database itself but also to data mining. In my Master's thesis, I proposed, under the most commonly used division of schemes, a new computing method that strikes the best balance to date between cost and computation performance. In the capacity of a system analyst and project engineer, I have worked with all kinds of software applications, and created a lot of my own as well. I once provided a model for the routine on form, which dominates daily operations in many offices. Some of my work already stands on fore front of the technological progress in China. Some time ago, I met the President of the New Technology Development Company affiliated with Beijing University, one of China's most distinguished higher-learning institution. He told me that about their new product, a program of textual search within whole context, which can identify text titles and text intelligently. Much to my surprise, I found that the program was virtually the same as the form-based handling system. If I had done a proper job in disseminating what I had done, there would be this repetition of work.
I have developed some insights about the WWW technology, which is now part of the normal office environment. Its widespread use has generated a lot of demands for change in the format of both the web server and the web browser. One answer to some of the demands is being met by the adoption of the intranet technology. With it, the architecture of CGI, +SQL DB+WEB SERVER has become a popular topic. I tried my hand in this area several years ago, and would dearly love to enhance my expertise.
The ands-on experience in so many different areas has endowed me with string sensitivity to changes and progress in computer science, particularly to problems that arise out of routine work. I am known among my colleagues for my ability to ask the right questions at the right moment, especially when dealing with DB, query tools, office models and the Internet. With further training, I hope to be able to combine ANN or other AIs with DB for information handling. I am glad to say that my competence at independent research will serve me well as I try to put my ideas into practice.
In view of the above, I would greatly appreciate it if you could accept me into your program and offer me whatever financial you might be able to. By giving me an opportunity to study under your seasoned guidance, you will produce not only another computer scientist but also a computer scientist who will spawn many other computer scientists.
