I am the director of the Pain Science Technology And Research (STAR) Lab. The mission of the Pain STAR Lab is to foster collaboration between clinicians and researchers aimed at developing, testing and validating novel technologies and methods to diagnose and treat chronic pain. The research vision encompasses hypothesis-driven and data-driven scientific discovery leading to translational research.
Our research program is guided by the scientific premise that sensory and emotional states are governed by neural circuits. Our main goal is to elucidate and map these circuits with unprecedented cellular specificity and temporal resolution, using multidisciplinary research tools such as optogenetics, self-report behavioral paradigms, and high-density (>200 units) neural recordings in vivo across the spine-brain continuum. Basic science discoveries are then translated to biomedical applications in collaboration with healthcare partners, using non-invasive brain imaging and machine learning.
Chronic pain is one of the most widespread, costly and disabling health conditions in the United States. Musculoskeletal pain is the most common type of chronic pain, and chronic low back pain is highly prevalent in this category, with healthcare costs estimated at $100 billion annually.
Our research is based on emerging scientific findings showing that pain is mediated by brain activity. Therefore, our main goal is to define the brain networks mediating pain. Our strategy is to reduce scientific theory to clinical practice using non-invasive brain imaging and big data analytics, thus enabling accurate classification and assessment of patients with pain, and providing healthcare professionals the opportunity for earlier interventions to prevent long-term pain, disability and opioid use.

In a new study led by Carl Saab, PhD, and published in NeuroImage, researchers have developed a novel methodology that combines electroencephalography (commonly called EEG) and artificial intelligence to diagnose pain. This marks a giant step forward in objectively diagnosing pain, which has long been a difficult and inaccurate process that relies almost entirely on self-report.
