[1][2] Bern's dissertation manuscript can currently be found in Lawrence Berkeley Laboratory's archives, examining "possible nonperturbative continuum regularization schemes for quantum field theory which are based upon the Langevin equation of Parisi and Wu.

The new theoretical developments of the 1990s and 2000s came in time for a renewed interest in extensive calculations in the context of the experiments at the Large Hadron Collider.

[5] The method of generalized unitarity provided new insights into the perturbative treatment of N = 8 supergravity and showed that there is a smaller degree of divergence than expected; higher-loop evidence suggested that "N = 8 supergravity has the same degree of divergence as N = 4 super-Yang–Mills theory and is ultraviolet finite in four dimensions".

[6] Prior to this, it had been generally assumed that quantum gravitation from three loops resulted in uncontrollable divergences.

[7] In 2014, he received the Sakurai Prize with David A. Kosower and Lance J. Dixon for "pathbreaking contributions to the calculation of perturbative scattering amplitudes, which led to a deeper understanding of quantum field theory and to powerful new tools for computing QCD processes.

"[8] In 2023, Bern and his collaborators David A Kosower and Lance J Dixon were awarded Galileo Galilei Medal from Italy’s Instituto Nazionale di Fisica.
