Recent research involves new technologies to monitor patients during sleep remotely; using simplified, wearable devices to enhance patient management. He was awarded a grant from the National Institute of Health (NIH), as principal investigator, on a study monitoring pregnant women throughout gestation, capturing the onset of obstructive sleep apnea using wearable technology. He is also the chairman of a task force sanctioned by the American Dental Association (ADA), Children’s Airway Screen Taskforce (CAST), directed to develop a new protocol for screening young children for sleep-related breathing disturbances, Children’s General Airway Screen Protocol (CGASP), for the detection of obstructive sleep apnea (OSA) allowing for early intervention in young children, focusing on reducing the burden of obstructive sleep apnea in future generations.

He trained under the mentorship of the “father of sleep” William Dement, MD, PhD and sleep medicine pioneer who discovered the Upper Airway Resistance Syndrome, Christian Guilleminault, MD, while at Stanford University. Dr. Simmons is an early pioneer in the study and education of enhancing awareness of the important relationship between—clenching/sleep bruxism/TMJ disorder with OSA, as well as the relationship between ADHD and disturbances of sleep, having lectured to the healthcare community on these topics for approximately 30-years.

Also, education is an important aspect of his career, by training medical students, residents, and fellows in sleep medicine. Then establishing the SEC as an outreach to educate the healthcare community. He was instrumental in guiding the Texas State Board of Dental Examiners, leading to the new rules requiring dentists to obtain specific education in sleep medicine to provide appliance therapy to patients with OSA.

Collaboration has been a central theme for Doctor Simmons throughout the years, having worked closely with dentists since the mid-1990s and other types of healthcare professions, and he sits on the board of many organizations, including the American Academy of Physiologic Medicine and Dentistry, which promotes an annual Collaboration Cures conference.
