Esther began playing the violin at four years old and made her concerto debut aged eight. At 16 she became the youngest prizewinner of the International Jean Sibelius Violin Competition and two years later was one of the youngest ever prizewinners of the Queen Elisabeth Competition. In 2014 she became a BBC Radio 3 New Generation Artist and in 2018 was selected as one of Classic FM’s Top 30 Artists under 30. In 2020 WQXR named her one of 20 “Artists to Watch.”

She performs with leading conductors—including Vladimir Ashkenazy, Gustavo Dudamel, Esa-Pekka Salonen, Myung-Whun Chung, Vasily Petrenko, Thierry Fischer, Karina Canellakis, and Andrew Davis—and orchestras such as the Los Angeles Philharmonic, Philharmonia, Seoul Philharmonic Orchestra, Deutsche Radio Philharmonie, BBC Symphony Orchestra, and the Royal Liverpool Philharmonic. She has performed at a range of prominent festivals, including BBC Proms and Aspen Music Festival, and has appeared in recital at Lincoln Center and Wigmore Hall. The Royal Philharmonic Orchestra appointed her as their inaugural Artist-in-Residence in 2018, through which she participated extensively in educational and outreach projects, alongside concert performances in London and across the UK.

Esther has recorded the Sibelius, Glazunov, Tchaikovsky, and—most recently—Barber and Bruch concertos for Deutsche Grammophon. She featured prominently on the soundtrack and accompanying disc of the feature film On Chesil Beach and is a guest artist on pianist Chad Lawson’s album breathe, both released by Decca Records and recorded at Abbey Road Studios.

Deutsche Grammophon has also released two recordings by the Z.E.N. Trio, which she founded together with fellow BBC Radio 3 New Generation Artists Zhang Zuo and Narek Hakhnazaryan, and which tours widely in North America, Europe, Asia, and Australia. The first album includes works by Brahms and Dvořák, and is followed by Burning Through the Cold featuring piano trios by Shostakovich, Babajanyan, Rachmaninoff, and Khachaturian.

Esther has curated a two-hour special programme for BBC Radio 3 and is a frequent contributor to BBC Music Magazine, Gramophone, The Arts Desk, and The Strad, which featured her on the cover of its August 2021 edition. She writes not only about repertoire and practice techniques, but also about less commonly explored areas, such as the mental health and wider well-being of musicians.
