She served as an ambassador of her home country while living with an American host family, who became her second family. Yuliya returned to the U.S. to pursue pre-medical undergraduate studies in Biology at the University of Delaware, where she discovered a passion for research. She conducted biochemical research for two years, where she studied the function of selenoproteins in order to understand their role in cellular homeostasis and tumorigenesis. Yuliya then moved to Michigan to pursue her goal of becoming a physician-scientist by enrolling in the combined D.O. - Ph.D. program at Michigan State University. Her lab research examined the pathogenesis of ankylosing spondylitis and investigated the role of immune modulators as novel therapies. During clerkships, Yuliya discovered a passion for neurology and decided to pursue her career as a physician-scientist in neurology with plans to conduct research in immune-modulated neurologic diseases. Outside of medicine, Yuliya enjoys hiking, bicycling, figure skating, and cooking. During a trip to the Pacific Northwest several years ago Yuliya and her partner Luul fell in love with the PNW, and they are thrilled to be back in Portland with their cat Bella.

Alicia Dupre, M.D.
Alicia Dupre grew up in small town Barrington, New Hampshire where she spent her free time around dogs and flying planes before traveling down to Boston for college and Medical School at Boston University. A history buff, Alicia loved the “Wicked” old buildings and atmosphere of New England, and throughout college split her time between a Cellular, Molecular, Genetic Biology Major and a History Minor before finding her place in medicine after volunteering with Boston Children’s Hospital. Throughout medical school, she continued volunteering, engaging with Boston’s homeless population on once-monthly Tuesday evenings and Parkinson’s Patients on Sundays. It was through these extracurriculars that she came to love Neurology, in particular the Neuro-ICU. However, she was not just content with exploring the brain on Earth, and was fortunate to spend time researching our bodies in space with NASA at the end of her medical school career. She saw the Pacific Northwest for the first time when she started her PGY-2 Neurology year Bootcamp but is loving everything about it. In her spare time, she loves reading, is a huge movie buff, spending hours at the beach or on the water, and taking up new hobbies such as Paddleboarding, learning the Ukulele, and trying to understand the piano.

Michelle Nguyen, M.D.
Michelle Nguyen was born in SoCal but grew up in the boonies of the San Francisco Bay Area. For college, she moved across the country to Alabama where she reluctantly adopted the phrase “y’all” and discovered her secret talent of eating her weight in crawfish in record times. She studied Neuroscience and Philosophy at the University of Alabama at Birmingham (UAB) and became interested in public health and addressing health inequities. Throughout her undergraduate career she volunteered her time as a counselor for the Crisis Hotline, worked as a rural medical outreach volunteer, and founded a chapter of PERIOD, an organization promoting equitable access to menstrual hygiene products and empowering menstruators to take charge of their lives through advocacy, education, and service. She stayed at UAB for medical school where she continued to work with underserved populations and discovered her passion for Neurology, engaging in multiple QI projects related to stroke and memory disorders. In her free time, she loves to hike, make origami, eat spicy food, and watch sci-fi/dystopian television shows. After a long stint in the southeast, Michelle is thrilled to be returning to the west coast (best coast) and fulfilling her long-time dream of living in the Pacific Northwest.

Daniel Quinlan, M.D.
Daniel was raised in Eagle River, Alaska, located 20 minutes north of Anchorage. He received his Biology degree at the University of Alaska Anchorage, and during college, researched Alaskan ethnobotanicals and worked in mental health and as a scribe at his local ER. During medical school at the University of Washington School of Medicine, he volunteered by talking to high school students about careers in medicine and worked for a year as a pathology “post-sophomore fellow” in the UW pathology department. Ultimately, he followed his original passion for Neurology with plans to return home to Alaska to serve his community. Outside of medicine, Daniel loves rock climbing, mountain biking, reading, movies, and playing board games and video games with friends. He also enjoys spending time with his partner and his dog, Axel. Daniel is thrilled to stay in the Pacific NW, and to train in Portland at OHSU.

Paige Skorseth, M.D.
Paige was born and raised in Baldwin, Wisconsin. She moved to River Falls, Wisconsin prior to high school, and then attended DePaul University (Chicago, IL) for her undergraduate degree in Bioscience. At DePaul, Paige was also captain of the cross country and track & field teams. It was her experience as a Division I athlete that interested her in the role of lifestyle, and specifically diet and exercise, in neurologic disease. She returned to the University of Wisconsin School of Medicine and Public Health for medical school. During her medical school time, she also pursued certificates in clinical research and public health. Some of her past research has focused on eating disorders and iron deficiency in elite athletes, parental and patient expectations for the diagnosis of pediatric concussion, ketogenic diet in pediatric epilepsy, and the correlation of concussion outcomes with certain social determinants of health. Her hobbies include kiteboarding, surfing, trail running (often with her parents), fishing, hiking, and traveling. This year, she is looking forward to making new friends, entering the amazing Portland running scene, and visiting every yurt in the Pacific Northwest.
