Synchronization is one of the fundamental phenomena in complex systems and nonlinear dynamics. There are a large number of systems where synchronization is an important effect and we shall focus on two of them:
a) Mobile systems: the emergence of coordinated movement in space and time without an apparent controller.
b) The Janus-faced nature of synchronization in brain dynamics, or how synchronization impairs and drives the brain, and the importance of physics for the prediction of epileptic seizures.
The school will cover:
– A general introduction to synchronization phenomena;
– Systems where spatial and temporal synchronization occur simultaneously, as observed in sperm cells, starfish embryos and swarmalators in general;
– Introduction to epilepsy and seizure dynamics;
– Seizure prediction methods: Modern nonlinear models for the detection and forecasting of dynamical transitions from time series; challenges and opportunities for more efficient data analysis.
The event will also include a workshop on the weekend of February 8-9 covering current research in the field.
This school is part of the Topics in Nonlinear Science: Fundamentals and Applications.
There is no registration fee and limited funds are available for travel and local expenses.

Attention! Some participants in ICTP-SAIFR activities have received email from fake travel agencies asking for credit card information. All communication with participants will be made by ICTP-SAIFR staff using an e-mail “@ictp-saifr.org”. We will not send any mailings about accommodation that require a credit card number or any sort of deposit. Also, if you are staying at Hotel Intercity the Universe Paulista, please confirm with the Uber/Taxi driver that the hotel is located at Rua Pamplona 83 in Bela Vista (and not in Jardim Etelvina).
BOARDING PASS: All participants, whose travel has been provided or will be reimbursed by ICTP-SAIFR, should bring the boarding pass upon registration. The return boarding pass (PDF, if online check-in, scan or picture, if physical) should be sent to secretary@ictp-saifr.org by e-mail.
COVID-19: Brazilians and foreigners no longer have to present proof of vaccination before entering the country.
Visa information: Nationals from several countries in Latin America and Europe are exempt from tourist visa. Nationals from Australia, Canada and USA will be required to obtain a tourist e-visa for visits after April 10, 2025.
Accommodation: Participants, whose accommodation will be provided by the institute, will stay at Hotel Intercity the Universe Paulista. Hotel recommendations are available here.
How to reach the Institute: The school will be held at ICTP South American Institute, located at IFT-UNESP, which is across the street from a major bus and subway terminal (Terminal Barra Funda). The address which is closer to the entrance of the IFT-UNESP building is R. Jornalista Aloysio Biondi, 120 – Barra Funda, São Paulo. The easiest way to reach us is by subway or bus, please find instructions here.
Poster presentation: Participants who are presenting a poster MUST BRING A PRINTED BANNER . The banner size should be at most 1 m (width) x 1,5 m (length). We do not accept A4 or A3 paper.
