Workshop on Time Series Analysis

22-24 November, 2022

The University of Auckland, Grafton Campus

The workshop aims at mathematicians, physiologists, engineers and scientists who are not expert in time-series analysis and will provide theoretical background as well as hands-on experience.

You will learn how to detect oscillations, discern determinism from seemingly noisy data and infer interactions and couplings between oscillatory processes.

Attendees will have the opportunity to analyse their own signals. A toolbox MODA (Multiscale Oscillatory Dynamics Analysis, https://github.com/luphysics/MODA) will be introduced and guidance on how to use it will be provided.

Our invited speakers include Prof Aneta Stefanovska,  Lancaster University, UK, Prof Peter McClintock, Lancaster University, UK, and Associate Professor Jeffrey Hogan, the University of Newcastle, Australia.

See detailed program below.

Registration is free, however, the workshop is now at full capacity. You can still register your interest by filling in the form below and we will contact you if there is any cancellation. If you have questions, you can email the organisers directly: workshop@insightfulmodelling.com

New Zealand-based Students who live outside Auckland and wish to attend the workshop might be able to receive some financial support. Please write to the organisers (email: workshop@insightfulmodelling.com) stating the title of your project, name of your supervisor and your university.
