In 1990, she was awarded a full scholarship by the Japan Solidarity Committee for Asian Alumni to pursue the Bachelor of Music degree in the Musashino Academia Musicae in Tokyo, Japan. There she had the opportunity to study with the world-renowned violist, Prof. Ulrich Koch. In 1995, having been awarded the Graduate Merit scholarship from the University of Michigan and the National Arts Council Arts Bursary, she pursued the Master of Music performance degree at the University of Michigan in Ann Arbor, Michigan, USA, studying with Prof. Yizhak Schotten.

Upon returning to Singapore in 1997, Judy joined the Methodist School of Music as a faculty member and pedagogy coordinator, teaching the violin, viola and music appreciation classes. Other teaching engagements includes chamber music coaching at Raffles Institution (Junior College), Anglo Chinese Junior College, and as a viola tutor in the Singapore National Youth Orchestra and the Methodist Girls School.  She is also an adjunct faculty in School Of The Arts, teaching the viola.  In addition to an active teaching schedule, she also performs with various ensembles, like the Metropolitan Festival Orchestra and the Re:Sound.
