Simon is a high energy theorist whose interests center on the exploration of theories of elementary particles and their interactions which go beyond the so-called Standard Model of particle physics. Simon uses the ideas and tools of lattice field theory to study these theories at strong coupling using supercomputer simulations.

In particular, he has worked on discrete approaches to quantum gravity and has pioneered the study of supersymmetric lattice gauge theories in particular the famous N=4 Super Yang-Mills theory that forms the cornerstone of the AdS/CFT correspondence relating gauge theories to gravity.

He is also worked on mechanisms and models of dynamical symmetry breaking such as technicolor and composite Higgs models.

Most recently he has become interested in the construction of tensor network formulations of lattice field theories. Such approaches have the potential to avoid the notorious sign problem that plagues Monte Carlo methods of simulating quantum field theory and connections  can be drawn to holography and quantum gravity. Such approaches also can serve as the first step in a reformulation of QFTs suitable for quantum computation.
