Understanding and treating persistent dizziness through active inference and the lived experience of the person.
I’m a physical therapist and co-founder of Two Trees Physical Therapy in Ventura, California, where much of my work is with people living with dizziness. With research collaborators, I’ve developed a framework that explains why dizziness (and similar conditions, such as pain) can persist, and how recovery comes through re-engaging with what matters to the person. I share it through research, teaching and writing.
Research
An active inference account of persistent dizziness, built with the patient’s lived experience at its center.
Teaching
Integrative Spin on Dizziness, a six-hour CEU course approved in California, Oregon, Washington and Nevada, plus guest lectures for DPT and residency programs.
Writing
Occasional letters to colleagues on dizziness, affordances and the science of making sense of the world.
