Dr. Rika Yoshii

Dr. Yoshii received her Ph.D. Degree in Computer Science from the University of California, Irvine (UCI) Before she joined the Department, she was a project leader at Rockwell and a research staff member for the Northrop Research and Technology Center, and then returned to UCI as a researcher for the Educational Technology Center and a lecturer for the ICS department. She joined the Computer Science Department at CSUSM in 1993. She is a U.S. citizen. And she is a proud graduate of the local Point Loma High School (Go Pointers!!)

She is also the Graduate Advising Coordinator of CS.

She is the Chair of the Governance and Planning Committee of the college.

She is a member of the Graduation Initiative Steering Committee.

Background

Why I Chose Computer Science:
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, and Medicine.

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!
