Nicholas Stergiou, PhD

University of Nebraska Omaha, USA

Ana Diniz, PhD

Faculdade de Motricidade Humana – Universidade de Lisboa, Portugal

João Rocha Vaz, PhD

Universidade Europeia, Lisboa, Portugal

Luís Silva, PhD

Coordination

Pedro Pezarat-Correia, PhD

Faculdade de Motricidade Humana – Universidade de Lisboa, Portugal

Participants will learn how to use nonlinear methods to analyze real biological data by first learning about the underlying mathematics of each nonlinear method in a simple and friendly way. Participants with varied backgrounds are welcome.

The workshop includes a strong practical component. Instructors will use class discussions and hands-on practice to facilitate understanding of the material covered in the lectures. Additionally, the participants will have the unique opportunity to discuss their own works/projects in individual sessions with Professor Nick Stergiou.

Prerequisites

At the beginning of the course, participants are required to show evidence of having:

Knowledge of college algebra, basic trigonometry, basic statistics and basic computer skills (needed to be successful in this workshop). This course is designed to be a comprehensive introduction to nonlinear analysis tools. Researchers, clinicians, and graduate students of all levels are encouraged to attend.
