College of Science

Eight UA science disciplines are in U.S. News & World Report's top 20. 

The University of Arizona is a Research University engaged in extensive research.  Why is that important for undergraduates?  Research-focused universities attract top faculty members who in turn attract substantial grant money to perform their research, improving education opportunities for students. 

Because of this, even as undergraduates, students have opportunities to become involved in cutting-edge research.  In fact, approximately 60 percent of the undergraduates in the College of Science conduct independent research with faculty members.  Undergraduates receive excellent quantitative and analytical training and coursework.  They also learn teamwork, time management, critical thinking and problem-solving skills.  Graduates move on to challenging jobs right out of college or to graduate, medical and professional schools where they enjoy very high acceptance rates.
