I am a postdoctoral fellow in the Department of Mathematics at the University of Toronto, under the supervision of Prof. Robert Jerrard and Prof. Robert McCann.
I did my Ph.D. at the Hebrew University of Jerusalem, under the supervision of Prof. Raz Kupferman, and my M.Sc. at Tel-Aviv University, under the supervision of Prof. Eilon Solan.

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

My research is mostly at the interface of non-linear elasticity, materials science, differential and Riemannian geometry, and the calculus of variations.
I am also interested in game theory (though currently I am not working in this field).

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.
