Thoughts on her Dartmouth Hitchcock Medical Center Sleep Fellowship:

Eva Mok, MD

"I thoroughly enjoyed my time during Sleep fellowship at Dartmouth Hitchcock Medical Center. There were plenty of opportunities to see the full range of sleep pathologies including sleep-disordered breathing, parasomnias, circadian rhythm disorders, sleep-related movement disorders, insomnia, and hypersomnolence disorders such as narcolepsy. It was very clear that my education and learning was a top priority. I also completed a research project on OSA and influenza that I am proud of and presented a poster at the annual AASM Sleep conference. I learned a lot and felt very well prepared for the next step in my career after fellowship; as a full time Sleep physician seeing both adults and children at another academic institution.

On my days off, I had opportunities for excellent outdoor activities including snowboarding at the nearby world-class ski resorts in the winter and hiking in the breathtaking, Instagram-worthy, New Hampshire mountains during spring and summer."
