  • Undergraduate: I never went to college as we go to medical school right after high school in Russia.
  • Medical School: Rostov State Medical University, Rostov-on-Don, Russia
  • Interests: I have a soul of a writer and love to write notes about memorable events that I witnessed or about topics that I am interested in and want to dig deeper. This is my way to explore the world and organize my knowledge of any kind. I also like reading, mostly classic books and autobiographies. Agatha Christie’s Autobiography is my all-time favorite. Since I don't want to turn into a complete bookworm, I love to go camping and hiking. And I couldn't find a better place for these hobbies than Oregon.
  • Favorite spot in Portland: As I am new to the city and due to the COVID lockdown I didn’t have much opportunities to explore Portland yet, so for now my favorite spot in Portland is an Aerial Tram cabin where I can catch up a breathtaking view every single day on my way to the OHSU. 
  • Fun fact: I grew up on the shores of the Arctic Ocean and used to meet polar bears on my way to school, so I am a living proof of the myth that Russians are friends with bears.

  • Undergraduate: Colorado College
  • Medical School:  Oregon Health & Science University
  • Interests: Within pathology I have an interest in hematopathology. In my home life my main interest is spending time with my wife and our dog, and together we enjoy many of the delights Oregon has to offer: I love to forage wild edible mushrooms in the spring and fall, explore different cultures through travel and food, identify and photograph plants and animals while hiking and backpacking. More recently, I’ve taken up growing tropical ferns from spores I’ve collected on past travels and propagating my own tropical house plants. Each fall I usually buy 500lbs of apples, press and ferment them, and make hard cider. This year I am going to try my hand at making wine and mead. Then there is the obligatory Oregon outdoor scene; I love to resort and backcountry ski, climb mountains, go for long runs, surf, skateboard, and rock climb. 
  • Favorite spot in Portland: Wildwood Trail, Forest Park
  • Fun fact: Before medical school I ran a screen printing and design company with a friend and together we created the “Philosoraptor” as a t-shirt design which became one of the earlier internet memes and has spawned statues, tattoos, knockoffs, and very nearly a Taco Bell Super Bowl ad.
