Welcome to the Computer Science Department
at the University of California, Santa Barbara!

Why Computer Science?

Computer Science is an exciting, challenging, and growing field that impacts the world and everyday life in countless ways.

Computer scientists are involved in creating technology and systems that are used in a wide range of industries, including medicine, communications, entertainment, manufacturing, business, and science. CS research pushes the state-of-the-art in computing theory and practice, and it leads to new technologies that change the world.

Despite all the impressive achievements of the field, we are convinced that there are many more exciting discoveries and applications of computer science yet to come, and you can be part of this process of exploration, discovery, and invention!
