Lin was born in Taiwan and raised in Austria. She studied music at Vienna's Hochschule für Musik with Noel Flores and later on at the Peabody Conservatory in Baltimore with Julian Martin. Lin continued studies even after launching her concert career, with her list of teachers including Richard Goode, Dmitri Bashkirov, and Andreas Staier. After her student years, Lin relocated to New York City, where she regularly appears in concert at 92nd Street Y, Miller Theater, and the Museum of Modern Art. She has also performed at Carnegie Hall and the Kennedy Center for Performing Arts. Lin has frequently appeared at major American and European festivals, including the Spoleto, Chopin, Ars Musica, and Archipel. Since 2014, she has joined Philip Glass to perform his Etudes on world tours.
Lin has recorded for the Hänssler Classic, BIS, Koch International, and Steinway Sons, among others. Her earliest recordings appeared at the beginning of the 21st century with a pair of acclaimed efforts on BIS: Chinoiserie, in 2000, containing Sino-inspired works by Adams, Arensky, Busoni, and others, and the complete piano works of Ruth Crawford Seeger, issued in 2002. Among her other recordings are a 2008 Hänssler Classic CD containing Bloch's Concerto symphonique, Concerto Grosso, and Scherzo fantasque, with conductor Jiri Starek leading the SWR Radio Orchestra Kaiserslautern; InsomniMania from the same year; and a 2011 disc of Mompou works. Lin was one of the first Steinway artists to record files on its Spirio player piano in 2015, using the instrument for a collaboration with Uri Caine entitled The Spirio Sessions. In 2020, Lin issued an album of Glass' piano works on Steinway Sons.
Along with her commercial releases, Lin has been featured across several different mediums, including a 2011 performance on NPR's Tiny Desk Concert, and in a pair of documentaries: Cooking with Jenny and Speaking for Myself. A noted educator, she is on the faculty of the 92nd Street Y and is also an author, having written a children's book titled Melody's Mostly Musical Day, which incorporates music spanning several eras. The book has since been performed as a multimedia concert series for schools and released as an album by Steinway Sons in 2016. ~ Robert Cummings & Keith Finke, Rovi
