Sandra Sinsch is a certified music pedagogue, music therapist and music geragogue. She studied at the national music universities in Hamburg and Trossingen, the University of Applied Sciences Munster and was a scholarship holder of the German National Academic Foundation. From 2011 to 2016, she was a lecturer at the ITU State Conservatory in Istanbul, after that she worked as a music pedagogue in Egypt. Today Sandra Sinsch works as a music therapist at the Salus State Hospital for Forensic Psychiatry Saxony-Anhalt in Stendal, Germany. The clinical pictures treated there are: Schizophrenic psychoses, personality disorders such as antisocial/dissocial personality disorder, borderline personality disorder/emotionally unstable personality disorder, sexual preference disorders, intelligence deficits, brain-organic disorders, autism and ADHD.

She uses active and receptive methods of Western music therapy as well as classical Arab and Ottoman music therapy. Since musical work in the context of custodial measures goes beyond conventional music therapy, she also integrates music education and music geragogical elements into her work. This is also reflected in the topic of her dissertation project conducted at the Catholic University of Eichstätt-Ingolstadt."Music education in the Forensic Psychiatry - conditional factors for strengthening resources and promoting participation, social learning and cultural education".

She is a member of the following societies: AMPF- Research in Music Education, German Society for Music Geragogy, DGM, German Society for Music Psychology, IASE- Islamic Working Group for Social and Educational Professions Germany.
