Ronald Chervi o I direct the University of Michigan's Sleep Disorder Center. And my job is split into three main parts. I see patients and read their sleep studies. I teach -- we train a good number of fellows. We have one of the largest sleep specialist training programs in the country. And I'm involved with research to figure out how we can diagnose sleep disorders better and treat them better. We have close to 20 faculty who are involved with the clinical Sleep Disorder Center. And they come from all walks of life. So people who get subspecialty training in sleep can come from pulmonary medicine or internal medicine or neurology or psychiatry or pediatrics or otolaryngology. And in fact, we have specialists from all those backgrounds who have trained in sleep and become sleep specialists. So it's a very broad-based and fertile grounds for us all to be learning from each other and providing what we hope will be the very best care for each patient that we see. One of the reasons that I'm in this field is because we generally have really good outcomes for patients. So we see patients who have been unhappy because they just can't stay awake during the day or they can't sleep at night, often for many years. And by the time we're done assessing them and treating them, we often have much happier patients. So I think probably some of the happiest patients in the Department of Neurology, which is my own particular department, are actually sleep patients. And it is very gratifying at the end of the day to have been able to help to that degree.
