Paula J. Babb, DO

  • Undergraduate: B.S. in Molecular Biology and Minor in Chemistry, Eastern Oregon University
  • Medical School: Western University of Health Sciences of the Pacific Northwest, Oregon
  • Interests: Regarding Pathology: Cytology, Gynecologic and GI Pathology. Regarding everything else and life in general: I enjoy hiking, skiing, biking, backpacking, art and spending time with my wonderful friends and loving family!
  • Favorite spot in Portland: Hoyt Arboretum, Tryon Creek park or anywhere else with a trail, some water and lots of trees!
  • Fun fact: I used to fight Wildland Fire for the US Forest Service before going to medical school. I eventually become a Helicopter Rappeller, which was an absolutely amazing way to get to some really remote places in the woods. These were very formative years for me and the stories I have are plentiful. My personal path to finding a love for Pathology was winding, and as I have learned, this is not an uncommon phenomena. Also, there are 1,400 species of bats, the largest of them is the golden-crowned flying fox (Acerodon jubatus) found only in the Philippines. These bats have a wingspan of 5 feet 6 inches!

  • 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.

Eric Nomura, MD

  • 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.
