With current skating partner, Annabelle Morozov, he is the 2024 CS Lombardia Trophy silver medalist.

[9] As a singles skater, Chen trained in Riverside, California, alongside his sister under Tammy Gambill.

[10] Chen then moved to Michigan to live with his mother, and he then changed coaches and began training with Marina Zoueva before the next season.

[6] Chen began skating with Katarina Wolfkostin in 2019, and he moved to train with her coaches, Igor Shpilband and Pasquale Camerlengo, in Novi, Michigan.

[17] The season was shortened due to the COVID-19 pandemic, with domestic competitions initially changed to a virtual format, leading up to the 2021 U.S. Championships.

[20] Wolfkostin/Chen then competed at the 2021 U.S. Championships, after Chen was medically cleared to skate after a second opinion was obtained following a knee injury, originally thought to be an incapacitating ACL tear.

Despite the injury, they placed first in both the rhythm and free dance, earning them the gold medal for the national title.

[21][22][23] Returning to international competition for the first time in over a year, Wolfkostin/Chen began on the Junior Grand Prix by competing at the first French JGP of 2021, in Courchevel.

[28] Due to the pandemic, the 2022 World Junior Championships could not be held as scheduled in Sofia in early March and, as a result, were rescheduled for Tallinn in mid-April.

[30] Wolfkostin/Chen were considered frontrunners for the title, however, following a fall at the beginning of the rhythm dance, they placed ninth in that segment, 6.40 points behind third-place Bashynska/Beaumont of Canada.

[32] Despite their disappointing result at the World Junior Championships, it did not alter Wolfkostin and Chen's plans to move up to the senior level for the following season.

"[33] In addition, Wolfkostin and Chen announced in May that they would be leaving coach Igor Shpilband to train at the new Michigan Ice Dance Academy in Canton, Michigan, under coaches Greg Zuerlein, Tanith Belbin White, and Olympic champion Charlie White.

[33] The team debuted new senior programs at the 2022 Lake Placid Ice Dance International, where they won the bronze medal.

[35] At their second Challenger, the 2022 CS Budapest Trophy, Wolfkostin/Chen won the bronze medal, setting three new personal bests in the process.

[41][42] At their second event, the 2023 JGP Hungary in Budapest, they placed first after the rhythm dance with a new season's best score.

"[44] In January, Pedersen/Chen placed third in the rhythm dance and second in the free skate to win the silver medal at the junior level of the 2024 U.S.

It was subsequently announced that they would be coached by Charlie White, Tanith Belbin, Nikolai Morozov, and Greg Zuerlein in Canton, Michigan.
