During the 1970s, large budget limits made it hard on the university's physical development; however, the 1980s saw a surge in money given to research in the social and physical sciences. At that time, the university's work in the anti-missile Strategic Defense Initiative and investments in South Africa caused anger on campus. During the 1980s and 1990s, the university used many resources to help rebuild its large hospital area and improve the academic buildings on the North Campus. The university also made computer and information technology on the campus important.
