Research

Collaboration + Applied Work

My research intersects autonomic regulation, interoception, trauma physiology, identity systems, and neuro‑innovation. I welcome inquiries related to research collaboration, applied psychophysiology projects, consulting, or interdisciplinary work connected to these domains. If you’re exploring a project or want to discuss potential partnership, you’re invited to reach out.

Autonomic‑Interoceptive Predictive‑Processing (AIPP) Model

A systems‑level model integrating autonomic regulation, interoception, and predictive‑processing to explain persistent multisystem symptoms in trauma‑exposed and psychosomatic populations.

This project develops the Autonomic‑Interoceptive Predictive‑Processing (AIPP) model, a unified framework describing how autonomic dysregulation, interoceptive appraisal, and predictive‑coding dynamics generate and maintain multisystem somatic symptoms. Drawing on psychophysiology, trauma biology, gut‑brain communication, and symptom‑network science, the model clarifies why symptoms persist in the absence of structural pathology and how chronic stress reshapes autonomic set‑points, precision‑weighting, and threat priors.

ENS–Brain Axis & Vagal Regulation

Exploring how the enteric nervous system, vagal tone, and gut‑brain signaling shape emotional regulation, stress physiology, and somatic symptom expression.

This project investigates the ENS–brain axis as a bidirectional regulatory system influencing autonomic tone, interoceptive accuracy, inflammation, and stress resilience. Areas of focus include vagal pathways, microbiota‑brain communication, neurogastroenterology, and the role of gut‑mediated prediction errors in symptom persistence. This work supports integrative approaches to trauma recovery, chronic stress, and multisystem dysregulation.

Digital Object Identifiers (DOIs)

DOIs serve as persistent, citable records of my research outputs. The DOIs listed here correspond to preprints, conceptual summaries, and manuscripts in progress, providing stable access points for readers, collaborators, and future citation.
