Lab Information

At the heart of the NeuroIntersect Lab is a mission to explore the dynamic connections between environment, vitality, healing, and neuroscience. Through collaborative efforts and engagement of clinicians, patients, scholars, and community members, the lab strives to:

  1. Produce meaningful, clinically relevant research that supports the health and vitality of individuals and communities.
  2. Communicate research in a relatable format that promotes integration of knowledge into daily life and clinical practice.

Significant areas of research and communication for the NeuroIntersect research ecosystem are complementary healthcare approaches to solving the well-being and health challenges of frontline workers engaged in community service or defense. Frontline workers are the backbone of our society, providing critical services that ensure public safety, health, and infrastructure. These dedicated professionals operate in high-pressure environments, often facing physical, emotional, and psychological stressors that impact their overall well-being.

Cognition Lab

Lead Researcher – Tahamina Begum, MBBS, PhD

CV

Lab Information

The Cognition Lab is a comprehensive platform for brain–behavior assessment and research that combines neurophysiological and behavioral measures to evaluate cognitive function in real time. Using event-related potentials (ERPs) and the NIH Toolbox Cognition, Emotion, Motor, and Sensory batteries, the lab assesses attention, memory, executive function, processing speed, emotional functioning, and more. By integrating objective brainwave data with standardized behavioral metrics, we create multidimensional cognitive profiles that support long-term monitoring, treatment evaluation, and the development of personalized, evidence-based care plans.

The lab advances interdisciplinary research in cognitive neuroscience and clinical science. In collaboration with Dr. Dominic Fetterly at NeuroLife Institute, we are conducting a Sports-Related Concussion (SRC) trial using the NIH Toolbox to assess cognitive and functional recovery. Through translational, practice-based research, the Cognition Lab connects neuroscience with chiropractic and complementary health care to improve mental health, cognitive performance, and overall to improve quality of life.

Lab Information

NeuroLab is an innovative research lab dedicated to the assessment of brain function, autonomic regulation, and emotional health across the lifespan from pediatric to adult populations. With a strong emphasis on neuroplasticity (i.e., the nervous system’s capacity to adapt and reorganize in response to internal and external influences), NeuroLab employs a multimodal approach that integrates objective measures (e.g., resting-state EEG, HRV, impedance cardiography, computerized neuropsychological testing) with subjective measures (e.g., parent-reported outcomes, patient-reported outcomes). A core focus of NeuroLab is investigating how complementary and integrative health (CIH) interventions, such as chiropractic care, influence neuroplastic changes and related physiological and psychological markers. Through this holistic framework, NeuroLab aims to advance understanding of mind-body interactions and optimize strategies for enhancing neurological adaptability, emotional regulation, and overall well-being in both children and adults.

SPORT (Sports, Performance, Optimization, Research, and Training) Lab

Lead Researcher – Amber Jackson, DC

CV

Lab Information

The SPORT lab is an innovation-driven research hub dedicated to advancing athlete health, performance, and evidence-based care. The lab operates under the guiding principle: “Built for Athletes. Powered by Evidence.” The lab is organized into four branches of research, with the SPEED Program (Sports Performance Early Evaluation & Detection) serving as the flagship initiative. SPEED drives innovation in optimizing athletic outcomes through cutting-edge assessments and training strategies. Complementing SPEED are three additional programs: one dedicated to clinical screening and prevention, ensuring early detection of risk factors; another centered on real-world outcomes research, translating data into actionable care models; and a program emphasizing education and workforce development, equipping clinicians, coaches and students with evidence-based tools. Together, these branches create a comprehensive ecosystem for advancing an athlete’s health, performance, and long-term success.

Salutogenic Research Catalyst Lab: Chiropractic, Population Health and Overall Well-Being

Lead Researcher– Christie Kwon, MS, DC, MPH

The research aims of the Lab for Salutogenic Research will focus on vitalistic exploration of the role of chiropractic care in overall well-being and quality of life. Research projects will explore the impact of vertebral subluxation correction on populations, at all stages of life and all stages of health. Dr. Kwon’s background in public health research lends to opportunities to explore the connection between chiropractic and public health concepts such as primary and primordial prevention, epidemiology, and causation. A focus on longitudinal outcomes, objective and subjective indicators of health, and preventative efforts through chiropractic will be hallmarks of each research project in this lab.

Chiropractic Education & Practice Lab

Lead Researcher – Billy C. Lunsford, BS, DC, MA, CSCS, CCEP, DACO, FIANM

This lab is dedicated to the fusion of understanding how to improve chiropractic education, and aiding practicing chiropractors by understanding symptom presentation, informing assessments, and developing effective treatment plans. Particular areas of interest are enhancing education within the basic, clinical, and chiropractic sciences. Additionally, I hope to discover practical methods for improving patient outcomes within the chiropractor’s office.
