VA Sleep

Why Sleep? A good night’s sleep not only can make everything feel better but is one of the most powerful things we can do for preventive health. Being able to guide my patients towards many good nights and better long-term health as a result is an honor and privilege. 

My favorite thing about Portland: Portland’s medical culture is so supportive and built around values of comradery and collegiality. Portland is also an incredible city that allows you to go for a hike filled with waterfalls during the day and finish with an incredible meal at a local restaurant to round out the night.

VA Sleep/Pulmonology and Critical Care

Why Sleep? I chose sleep because it is an uncharted fascinating field of medicine! I was struck the very first time I heard “we spend a third of our lives asleep and we don’t understand why we sleep”.  There is still so much to learn about sleep medicine and the more we know the more we are finding how it much it impacts people’s lives.  As a critical care physician, I saw first-hand how important sleep is for people with critical illness and in my pulmonary medicine practice we treat sleep disordered breathing every day. So essentially, I find sleep medicine a fascinating field which impacts society in ways we continue to discover.

My favorite thing about Portland: The vast array of parks and outdoor spaces.  You can hike in the Gorge, on Mt Hood, at the Coast or just in one of the many city parks and have a great experience.

VA Sleep/Neurology

Why Sleep? It is a young and exciting field that is rapidly evolving and has a lot of opportunities. I also love the interdisciplinary nature of the field which challenges me to keep learning not only about new developments in neurology but also in other fields such as medicine, psychiatry, and pediatrics. 

My favorite thing about Portland: It’s a city big enough to have everything you’d want from an urban area but not so big that it’s hard to navigate. The people are super friendly. You are surrounded by very diverse geography with the beach being less than 1.5 hours to the West and the high desert being 1.5 hours to the East.

VA Sleep/Psychiatry

Why Sleep? I’ve been interested in sleep since I was a child and my interest in sleep has become very much intertwined with my study of circadian physiology over the last 25+ years.  I was originally drawn to sleep out of a curiosity about the functions and nature of a complex brain-state in which we spend so much of our lives.  Later it was the near 24-hour rhythmicity in so much of our biology (and particularly in sleep and wakefulness) that captured my imagination.  Being able to apply this knowledge to help those suffering from sleep disorders is incredibly rewarding.

My favorite thing about Portland: I have a strong community of friends who live in Portland and it is a very quirky and livable city where I can walk to work year-round.

Kimberly Hutchison, MD

OHSU Sleep/Neurology

Why Sleep: I have always been interested in the brain, and in particular consciousness.  Sleep medicine gives me the chance to study the mysterious state of sleep while helping both healthy and ill patients function at their best.  

My favorite thing about Portland: My favorite thing about Portland is all the parks to run in...and the proximity to the beach…and the mountains.  The skiing!!!  Did you say one thing???

Miranda Lim, MD

Miranda Lim, MD

VA Sleep/Neurology

Why Sleep? My research program centers around understanding the function of sleep - one of biology’s greatest mysteries. I am constantly thinking about why we sleep -- whether I am helping patients with neurological disorders or examining sleep across the lifespan in our preclinical animal models.

My favorite thing about Portland: Having lived previously in the Southwest, South, Midwest, and East Coast areas of the US, there is no better place than the Pacific Northwest. Portland in particular combines the best of all worlds - great weather, progressive people, low cost of living, no traffic, mountains/coast/vineyards/desert all within just a couple hours’ drive. We have a creek in our backyard and yet we live only 10 minutes from OHSU and great city life downtown. My favorite thing about Portland is everything!

OHSU Pediatric Sleep/Pediatric Pulmonology

Why Sleep? Sleep chose me. I started out by reading 3-channel studies with impedance sensors and oximetry on infants in the hospital. I remember flipping through stacks of hundreds of pages, marking events with a pen, adding up the events, counting recording hours and calculating apneas per hour. Lucky for me, one of the adult psychiatrists, Dr. Bob Sacks, had established a small 4 bed sleep lab in the Hatfield research building (parents had to sleep on an exam table or sit in a rather uncomfortable chair during the study). I teamed up with one of the pediatric psychiatrists and we started doing full sleep studies in children in the lab. Over the course of a few years, we established the pediatric sleep program that is now serving children with highly complex sleep disorders.

My favorite thing about Portland: That most people are happy to engage in a conversation about anything. The food. The summer weather.

OHSU Sleep/Anesthesiology

Why Sleep? As an anesthesiologist, I am especially interested in how sleep disorders can affect patients in the perioperative period.  Helping patients feel better by addressing their sleep issues is wonderful, and keeping them as safe as possible during the time around surgery is something I am passionate about.  

My favorite thing about Portland: My family moved to Portland in 2018.  I love that you can enjoy the city and all that it offers, as well as the gorgeous mountains and coast all in the same day!

Christian R. Morales Perez, MD

Christian R. Martin Morales, MD

VA Sleep

Why Sleep? I chose sleep medicine because I noted that it had far too few sleep doctors to address the highly prevalent sleep disorders. Treatment of these disorders can be life-changing to many patients.

My favorite thing about Portland: Portland has amazing summers with warm sunny days and blissfully low humidity, great for floating down the rivers. Portland also has an abundance of fruits right at arm’s reach. I love exploring the neighborhoods and picking cherries, pears, plums, and berries straight off the branch.

OHSU Pediatric Sleep

Why Sleep? I enjoy being part of a multidisciplinary program that strives for excellence in teaching, research, and providing high quality care to patients.

My favorite thing about Portland: I enjoy hiking, biking, and running on the many trails that Portland has to offer.

Asha Singh, MD

Asha Singh, MD

OHSU Sleep/Neurology

Why sleep? I love working as a sleep specialist at OHSU as I am able to help patients of all ages in treating their sleep disorders.  As we sleep 1/3 of our lives, it is important to optimize sleep to aid in daytime functioning. 

My favorite thing about Portland: My favorite thing about Portland is the food scene including the coffee.  I also enjoy exploring with my family the variety of hiking trails, skiing, and beaches!

Elizabeth Super, MD

Elizabeth Super, MD

OHSU Pediatric Sleep/General Pediatrics

Why Sleep? I enjoy helping children and families achieve restful and healthy sleep to improve their quality of life. Working in multidisciplinary teams to achieve better sleep and functioning for children is incredibly gratifying.

My favorite thing about Portland: Portland’s proximity to the Columbia River Gorge, Mount Hood, and the Oregon Coast enables lots of outdoor play in every season!

Jeremy Wearn, MD

Jeremy Wearn, MD

VA Sleep/Hospitalist

Why Sleep? Initially, my interest in the field was inspired by a fascination with the complex relationships in the foundational components of sleep medicine - respiratory dynamics, cardiovascular function, airway anatomy, and neurodiagnostics.  In practice, I appreciate the ability to develop meaningful patient relationships that can lead to transformative impacts on health, which is driven by a shared understanding of importance of a good night’s rest and the direct impact it has on one's mental and physical health.

My favorite thing about Portland: A very friendly and approachable city with access to outstanding outdoor activities and some the country’s best food and breweries
