This program is first-of-its-kind in India with a specific focus to provide research experience and training to highly motivated students and young researchers in the interdisciplinary field of complex dynamical systems theory that has applications in diverse fields in science and engineering, such as the study of biological systems, atmosphere and oceans, materials and structures, economics and social systems, archaeology and anthropology, languages, and many others.

The specific theme for summer-2016 program is "Geophysical Phenomena".

We especially encourage early graduate students, postdocs, and early faculty to apply for participation. Applications from exceptional advanced undergraduate students may also be considered, depending on their level of preparation.

This two month long program will consist of the following activities:

23 May - 04 June: Two-week preparatory summer school. Details of lecturers and topics are given below.
23 May - 23 July: Two-month summer research program. A few selected fellows will get a chance to work on a project mentored by an expert in mathematical modeling of geophysical phenomena.
18 - 23 July: One-week discussion meeting. The fellows will present their work during the summer, along with talks by other researchers. Considerable time will be reserved for discussions.
Throughout the summer months, we will also have active seminar series on various mathematical and physical aspects of earth sciences
