  Aron C. Wall is an American theoretical physicist, specializing in quantum gravity. He is Lecturer of Physics at the University of Cambridge, and is one of the winners of the 2019 New Horizons in Physics Prize.
  
  ## Biography and education
  
  He was born on June 7, 1984, the son of programmer Larry Wall. He received a B.A. in liberal arts in 2005 from St. John's College (Annapolis/Santa Fe) and a Ph.D. in physics in 2011 from the Maryland Center for Fundamental Physics of the University of Maryland, College Park, under advisor Ted Jacobson.
  
  From 2011 to 2014 he was a Simons postdoctoral fellow at the University of California, Santa Barbara, from 2014 to 2017 a fellow at the Institute for Advanced Study in Princeton, from 2017 to 2019 a fellow at the Stanford Institute for Theoretical Physics and since then a lecturer in physics at the Cambridge University Department of Applied Mathematics and Theoretical Physics.
  
  ## Research
  
  In 2016, together with Ping Gao and Daniel Louis Jafferis [de], he proposed a mechanism for traversable wormholes without exotic matter. It is based on the interpretation of wormholes as pairs of quantum entangled particles (EPR) by Leonard Susskind and Juan Martín Maldacena, known as the ER-EPR conjecture; however, Wall and colleagues did not use the usual Einstein-Rosen Bridges, but that their wormhole model provides a mathematically equivalent description to quantum teleportation.
  
  ## Controversies
  
  Following Wall's appointment to a lectureship in the Faculty of Mathematics, attention was drawn to his anti-LGBT views, expressed on his blog. Comments included accusing the “gay community” of living a “notoriously promiscuous, reckless, and obscene lifestyle”, saying that to sleep with someone of the same gender is to perform “unnatural sex acts”.
