I am a mathematician, working at the Einstein Institute of Mathematics in the Hebrew University of Jerusalem.

My research is mostly at the interface of non-linear elasticity, materials science, differential and Riemannian geometry, and the calculus of variations.
More recently, I became interested in infinite dimensional Riemannian geometry, in particular in the study of the geometry of shape spaces and diffeomorphism groups, and their applications.

In Hebrew, my name is written “שיא מאור”, and my first name is pronounced like the third letter in the English alphabet.

I have been playing the piano and composing music for many years, and had the honor of learning from some great musicians including Josef Bardanashvili, Amnon Wolman and Ilya Dimov (composition) and Sara Tal and Michal Tal (piano).
Below are some compositions and recordings (more to come soon):

  • Piano Sonata, third part (performed by Ruth Zori). Second prize, Yardena Alotin composition competition (2014), Bar Ilan university. First performed by Shira Shaked as part of the 2014 Piano Project of Stony Brook University.
  • Some recordings of my contrabass/piano free-improvisation duo with contrabassist/composer Orr Sinay.
