ICTP International Chairs

ICTP International Chairs are prestigious visiting positions allowing distinguished physicists and mathematicians to spend extended time at ICTP. While in Trieste, these high-level researchers deliver lectures, lead discussion groups, guide research, and mentor scientists from disadvantaged countries. They make an invaluable impact on ICTP’s community by providing a unique opportunity for scientists in all stages of their careers and from all corners of the world to have direct exposure to the world's best scientific talent. Those scientists, in turn, share their knowledge with colleagues and students in their home countries.

Ramanujan International Chair

ICTP's Ramanujan Chair is hosted in the Mathematics section and named in honour of Indian mathematical genius Srinivasa Ramanujan (1887 – 1920). Since 2025, the chair has been held by Brazilian mathematician Carolina Araujo of the Institute for Pure and Applied Mathematics (IMPA) in Rio de Janeiro, Brazil. An algebraic geometer specializing in birational geometry and foliations, Araujo is a distinguished mathematician and a promoter of women in mathematics, with longstanding connections to ICTP. 

Virasoro International Chair

The Miguel Virasoro Visiting International Chair is hosted in ICTP's Condensed Matter and Statistical Physics section. It was launched in 2024 and has since been held by Subir Sachdev, a condensed matter physicist known for his important contributions to the understanding of entangled states of quantum matter.
