I turn scattered results into one general theory — research knowledge that others can build on directly.
My work spans abstract algebra, invariant theory, topology and mathematical physics, carried out mostly at Göttingen, then at Moscow and Bryn Mawr.
The shape of this portfolio — taller means stronger evidence in that mode.
I am a mathematician: I developed the theories of rings, fields and algebras that shape abstract algebra, and I proved the two theorems that tie every continuous symmetry in physics to a conservation law.
