Nonlinear Analysis Core
Nonlinear Analysis Research Core
The Core currently has expertise in the following methods.
Annual Nonlinear Analysis Workshop
Every year the Core holds a workshop centered on the nonlinear analysis of human movement. Its purpose is to introduce research scientists, clinicians, educators and students to a variety of nonlinear methods. For more information please visit the Workshop’s webpage.
Please contact the Core for information on rates.
How to Initiate Work with the Core
- Compelte a Project Initiation Form and send it to firstname.lastname@example.org.
- This will be followed by a communication from the Core to better understand your needs.
- The Core will send a quote for the work.
- Provide to the Core data or other items needed to complete the work.
- Work commences.
- Dr. Nick Stergiou, Core Facility Director
- Dr. Jenna Yentes, Core Facility Associate Director
- Mr. Benjamin Senderling, Core Facility Coordinator
