Dear Prospective Employers;

I am seeking a position in AI/SE. As the included resume indicates, 
I am expecting to obtain my PhD degree concentrated on 
artificial intelligence and software engineering 
at Computer Science Department, Texas A&M University on 
December 1992. 
 
During the last two years, I have developed a specification
methodology for expert systems (TBSM) , accomplished a specification 
for R1/SOAR based on the methodology (in a reverse engineering
fashion), generated a formal foundation of the methodology, developed
an algorithm for verifying the specification 
for potential inconsistency, investigated issues regarding validation
of expert systems using the methodology, extended TBSM using fuzzy 
logic, implemented a knowledge acquisition tool (TAME) in a 
hypertext environment that supports the acquisition of the
specification, and used fuzzy logic for specifying imprecise 
requirements. Both TBSM and TAME are currently in
the process of patent application through the university.

My thesis work has lead to an accepted journal paper to appear in IEEE
Expert, two journal papers in review, a book chapter (two in review),
and eight conference and workshop papers. I have several 
years of experience as research associate, research assistant, as well
as teaching assistant at Texas A&M University, and a summer hiring
research programmer at IBM. I also serve as a consultant through SBIR 
to a NASA contract.

Should you desire any more information, please do not hesitate to
contact me. My email is yjlee@cs.tamu.edu, and phone numbers are (Home)

Sincerely Yours

CAREER OBJECTIVE

To utilize my education and experience in the areas of  
software engineering, artificial intelligence, hypertext, and real
time systems, and apply the research initiative to industry practice. 

EDUCATION
PhD in Computer Science at Texas A&M University (TAMU); Dec. 1992 (expected).
Master of Computer Science at Texas A&M University; Dec. 1988.
BS in Electrical Engineering at Chung Yuan Christian University; June 1984.

PATENT
Developed a task-based specification methodology and system which is in 
the process of patent application through Texas A&M University.

COMPUTER LANGUAGES AND SYSTEMS
o  Specification Language: Z.
o  Programming Language: C, LISP, Pascal, Fortran.
o  Interface Toolkit: Microsoft SDK Window Development, X-Window.
o  Expert Systems Language (Tool): CLIPS, OPS5, LOOM.
o  Hypertext system (language): KMS (action language).
o  Operating System: UNIX, MS-DOS.
o  Machine: SUN, Macintosh, TI-Explorer, Silicon-Graphics.

RESEARCH INTERESTS
o  Software engineering.
o  Artificial intelligence.
o  Fuzzy logic.
o  Hypertext.

My research plan consists of several tasks: 1) to use fuzzy logic as a
basis for soft functional requirements to tackle uncertainty issues in
classification type of expert systems and validation of expert
systems, 2) to develop the formal foundation for validation/testing of
software specifications in the context of TBSM, 3) to further explore
the issues of considering both specification and prototype
representation for the purpose of design in the framework provided by
TAME, 4) to automate the process of converting the prototype
representation to executable prototype systems, and 5) to conduct an
empirical evaluation of the TBSM. 

EXPERIENCE
o  Jan 1992 - Present: Teaching Assistant at Computer Science 
   Department, TAMU.
   o  Assist instructor in teaching C, Fortran, and Pascal computer
      languages.

o  Aug 1990 - Dec 1991: Research Associate/Assistant at Computer Science 
   Department, TAMU. 
   o  Developed a task-based methodology for specifying
      expert systems and other complex software systems.
   o  Accomplished a specification for R1/SOAR, in a reverse engineering
      fashion, using the task-based specification methodology.
   o  Generated the formal foundation for the task-based specification 
      methodology.

o  May 1990 - Aug 1990: Research programmer at the IBM Federal Systems 
   Division, Houston.
   o  Played a major role in developing a design methodology 
      (TOP) to facilitate the verification of expert systems,
      which is in the process of patent application.

o  Nov 1987 - Jan 1989: Research Assistant at Entomology Department, TAMU.
   o  Implemented an integrated information system combining user 
      interface, graphics, database, and simple rules to manage
      brush problems in Microsoft Window environment using C language.
