Early life and adult pain can have drastic effects on neurodevelopment and overall quality of life. In the Williams’ Pain, Aging, and Interdisciplinary Neurobehavioral (P.A.I.N.) Lab, our research focuses on behavioral neuroscience and the mechanisms of neurobiology and neurophysiology of pain processing, with a special emphasis on the neonatal. The ultimate research goal is to better understand, recognize, and alleviate pain in the newborn to improve the quality of life in adulthood by uncovering new assessment tools and interventional strategies. Our research interests include the mechanisms of neurobiology and neurophysiology of pain processing, neonatal pain, chronic pain, neurobehavior, osteoarthritis, translational medicine, anesthesia/analgesics, and evoked and non-evoked pain assessment tools. The P.A.I.N. Lab has both pre-clinical and clinical studies to help close the gap in translation.
