A research university is a university that is committed to research as a central part of its mission. It does not matter whether the institution is public or private, or how the research is funded. Such universities have a strong focus on research and often have well known names. Undergraduate courses at many research universities are often academic rather than vocational and may not prepare students for particular careers, but many employers value degrees from research universities because they teach fundamental life skills such as critical thinking. Globally, research universities are predominantly public universities, with notable exceptions being the United States and Japan.
