Born in Kwang-Ju, South Korea, Ji Oh immigrated to Los Angeles with her family when she was 16 years old. She was exposed to art from early childhood and was especially fascinated with color mixing and drawings. Receiving recognition for her talent in American high school was a big encouragement during her adjustment to life in America. She received her BFA from California State University Fullerton and her MFA from Claremont Graduate University in Drawing and Painting. As the representative of her graduate school, Ji participated in the Visual Art Competition for the Los Angeles Arts Council Art Scholarship Awards and was awarded the Second Prize. Following graduate school and an inspirational two-month solo backpacking tour of western Europe, Ji continued her art career and private teaching at her studio in Walnut, California. She has exhibited her artwork extensively at museums and galleries throughout the United States and internationally, including Australia, Japan, Korea, Mexico, and Singapore. In 1997, she was an instructor in painting and drawing at Idyllwild Art Academy. In 2002, Ji Oh was commissioned by the Kawaguchi Art Station in Kawaguchi, Japan to create art for the Lilia Cultural Center, and her work now resides in their permanent collection. Her most recent shows include solo exhibitions at the PYO Gallery in Los Angeles, and INSA Gallery in Seoul, South Korea. She has curated three art shows, including "Los Angeles Festival: Crossing LA", and has worked as a juror for the City of Beverly Hills Art Show, a panelist at the Watts Towers Art Center. In addition to being a guest art history lecturer at Patten University in Los Angeles, she has lectured on "Woman Artists Past & Present" at the Korean Cultural Center in Los Angeles, and Western art history lectures at the Andrewshire and Rubicon Galleries in Los Angeles. In 2013, she presented a lecture series on contemporary and post modern art at the Lynn J. Gallery in Buena Park, California titled "Love Art to Hate Art". Ji periodically conducts art history lecture series at her private gallery. She is teaching art at Ji's Art Studio in Southern California.
