[4] Weithaas worked for some years as a professor at the Berlin University of the Arts[3] and moved in 2004 to the Hochschule für Musik "Hanns Eisler".

[8] Harmonia Mundi has published her recordings of works by Béla Bartók, Johannes Brahms, Maurice Ravel, Henri Dutilleux, Claude Debussy and Franz Schubert.

[9] Weithaas partners with the pianist Silke Avenhaus on tours[10] and on five recordings of works by Schubert, Brahms, Felix Mendelssohn, Antonín Dvořák, Josef Suk and French composers on the label CAvi-Music.

[11] As the artistic director of Camerata Bern, Weithaas was responsible for the recording of two Beethoven works for the ensemble's 50th anniversary, the String Quartet No.

Fiona Maddocks, a reviewer for The Guardian, wrote in 2015 that a recording by Weithaas of Bruch's Violin Concerto reminded her "with quiet and compelling eloquence, why it's a masterpiece".
