**Frans Pretorius **is professor of physics at Princeton University. He holds a Ph.D. in physics from the University of British Columbia, in Vancouver, Canada. His primary field of research is Einstein's theory of general relativity, with a special emphasis on black holes. He is involved in understanding the nature of and gravitational wave emission from binary compact object mergers, where each member is either a black hole or neutron star. He also studies critical phenomena at the threshold of gravitational collapse, the stability and dynamics of higher dimensional black holes, and the nature of singularities that generically appear in black hole and cosmological spacetimes, among other topics. He received the Dirac Medal in 2021, the Galileo Galilei Medal in 2021, and the New Horizons Prize in Physics in 2016. He is an elected Fellow of the American Physical Society and the International Society on General Relativity and Gravitation.
