When I was in high school, I used to write 3 songs a day, mostly pop and soft rock.
I was influenced greatly by the Beatles and Elton John. It was very difficult and
time consuming to write music (I mean the notation). Then, one day, I read in the
LA Times about a computer program that could help us compose music. Without knowing
much about Computer Science, I decided to be a CS major. I worked for a short period
of time with a professor at UC Irvine, who had a project to generate simple songs.
It was just too simple. I have not given up on writing a program to generate the top
10 hits!!! But as a graduate student, I became more interested in the computer's power
to undertand natural languages. I wanted to see if the machine could help solve international
communication problems by automatically translating one language into another. Thus,
I chose this topic for my Ph.D. dissertation. I feel that you don't have to be a hack
or a technical genius to be in Computer Science. We can utilize the power of this
fascinating machine to make human lives better through Arts, Humanities, Sociology,
Why I am a Teacher:
I had one wonderful teacher in elementary school Ms. Mizugami who truly believed in
my talents, encouraged me and gave me confidence. When I wrote to her upon receiving
my college degree, she still remembered me. Then in this country, so many teachers
(Ms. Woodward is one of them) in junior high and high school gave me support and encouragement
to a girl who arrived here without knowing a word of English. They never said one
word of criticism. All I heard were compliments and support. This was completely different
from Japan. Even in college, teachers such as Dr. Standish and Dr. Bork gave me unconditional
support and guidance. They have changed my life forever. Without them I could not
have made it here today. That's why I am a teacher today. And so many students here
and at UCI have made me very glad that I chose to be a teacher. Being able to touch
their lives and seeing them become successful and happy - that is the greatest reward.
It is much much more important than money. I have only one advice for my students
and other young people. Believe in yourself and find something you truly want to do.
Then you will be able to attain that goal as long as you are willing to keep on working
at it and wanting it more than anything else. Don't ever doubt yourself!
