Born in 1979 in Kaunas. In 2007 she completed her composition  studies under Rytis Mažulis at the Lithuanian Academy of Music  and Theatre. In 2003 she took part in the Composition and Music  Technology Programme in Tampere. In 2004 she participated in masterclasses in Dundaga and Istebna, as well as the Acanthes  composition workshops in Metz, where she studied under Jonathan Harvey, Philippe Manoury, and Martin Matalon. In 2006 she  trained at the Stuttgart State University of Music and Performing  Arts under Marco Stroppa and Caspar J. Walter. She takes part in  a variety of interdisciplinary projects, composes music for dance  productions and films, and her works are regularly performed at  contemporary music festivals in Lithuania and internationally.

Many of her compositions reflect two long-standing areas of  creative interest: the relationship between textile patterns and  musical structures, and a fascination with the ideas of classical  Indian culture: its sound, scales and expressive states. Nearly all  of Medekšaitė’s works composed after 2005 are based on a technique she developed for translating textile patterns into musical  parameters. The starting point is a geometric weaving pattern;  the white and black fields of the grid (warp and weft) determine  sound parameters such as pitch, duration, dynamics and timbre.  Over time this principle has been combined with other compositional techniques, such as serialism, minimalism, microtonality, and stochastic composition. The composer emphasises that  almost all of her works could bear the title Textile, even though  they have been given more individual names.

The traditions of Hindustani music are also a source of aesthetic  and technological inspiration for her. This is reflected both in  the titles of many of her compositions—often referring to specific  ragas—and in her use of the scales and characteristic colouring  of that music, recreated using Western instruments, including  through the use of sustained drone tones.
