Each year the Institute is able to welcome a small number of doctoral students from institutions which are based abroad to spend a period of up to 12 months in order to benefit from access to the Library and other facilities in the Institute. Those interested should contact the Director, sending a short curriculum vitae in English, a one-page summary of their research topic, the dates of the projected visit and two letters of recommendation from academic referees. It is recommended that applicants write at least three months before they wish to arrive.
