Open Research Studies

​Here are our active research studies currently seeking volunteer subjects. Click on each study for more information. If you do not find any studies that you are currently qualified for or interested in but would like to be contacted for a future study, please join our registry and we will add you to our list of potential future subjects. 

OSA: If you have been diagnosed with obstructive sleep apnea

The Effects of Melatonin on OSA
This study aims to learn more about the effects of Melatonin treatment in patients with OSA. 
Chronic Obstructive Pulmonary Disease (COPD) and OSA
We will study people with OSA with and without COPD as well, to learn more about the differences in physiology, respiratory control, and inflammation between these two groups of patients. 
HIV and OSA
We will study OSA patients with and without a HIV-positive diagnosis to explore why people living with HIV on anti-retroviral therapy have a higher occurrence of OSA than people of similar weight and age. 
Tongue Exercises
This study aims to find out whether a set of tongue-strengthening exercises with a custom oral device might be an effective new treatment for OSA, by making the tongue stronger and less likely to collapse the airway during sleep. 

COPD: If you have Chronic Obstructive Pulmonary Disease with or without also having OSA

Chronic Obstructive Pulmonary Disease (COPD) and OSA
We will study COPD patients with and without OSA to learn more about the differences in physiology, respiratory control, and inflammation between these two groups of patients. We are currently recruiting subjects who have both COPD and OSA, but if you have COPD without OSA, let us know if you would be interested in being contacted when we are recruiting COPD-only subjects. 

HIV: If you have OSA and are also HIV-positive and taking Anti-Retroviral Therapy (ART)

HIV and OSA
We will study OSA patients with and without a HIV-positive diagnosis to explore why people living with HIV on anti-retroviral therapy have a higher occurrence of OSA than people of similar weight and age. 

Healthy subjects: If you do not have OSA and are otherwise healthy

Melatonin and Simulated High Altitude
This study will investigate how the supplement melatonin affects sleep, control of breathing, and brain function in the simulated high-altitude environment of a low-oxygen tent.
