Born in California to Korean parents, Angela started playing the cello at age 10. Performing from an early age soon thereafter, Angela won virtually every competition in Korea and made her debut with the Seoul Philharmonic at the age of 12. At age 14, she started her studies at the Curtis Institute of Music with Peter Wiley and the late Orlando Cole. While at Curtis, she made her debut with the Philadelphia Orchestra and Christoph Eschenbach.

In recent seasons, Angela has performed with Anne-­Sophie Mutter on her Virtuosi European Tour, Spira Mirabilis' Beethovenfest Bonn residency, the Marlboro Festival, and Camerata Salzburg. She has been awarded the Silver Medal and Seong­Yawng Park Talent Award at the International Isang Yun Competition, in addition to prizes at the Stulberg International Competition and the Young Tchaikovsky Competition.

Angela is active as a baroque cellist, often performing the Bach Suites on baroque cello, and has played continuo with Helsinki Baroque and Gamut Bach Ensemble Philadelphia. In addition to performing early music, she has a deep interest in the music of our times and is dedicated to playing the works of living composers, taking part in dozens of world premieres.

Angela also studied at the New England Conservatory (MM) and the Universität der Künste Berlin (Konzertexamen), where she was a DAAD Scholar (German Academic Exchange), graduating with highest distinction in 2013. She has also studied baroque cello at the Frankfurt Hochschule für Musik.

She is currently on the cello and chamber music faculty at the Carnegie Mellon University School of Music in Pittsburgh.

Angela plays a Tirolean cello from the late 18th century.
