The Institute for Advanced Study (IAS) is a private institution in Princeton, New Jersey, designed to foster research by scientists in a variety of fields without the complications of teaching or funding, or the agendas of sponsorship.
The IAS uses the word faculty in a special way and denotes a lifetime appointment. Although the faculty at the IAS do not teach classes (because there are no classes) they often do give lectures at their own initiative. Also they have the title Professor along with the prestige associated with that title. Furthermore they often direct research. This list includes all current and former Faculty members, and dates of tenure at the Institute.
