He received in 1982 his PhD in Astrophysical Sciences from Princeton University with thesis advisor Jeremiah P. Ostriker[1] and held postdoctoral positions at the University of California, Berkeley and the Canadian Institute for Theoretical Astrophysics in Toronto. Merritt's fields of specialization include dynamics and evolution of galaxies, supermassive black holes, and computational astrophysics.
Merritt is a former Chair of the Division on Dynamical Astronomy of the American Astronomical Society. He is a founding member of the Center for Computational Relativity and Gravitation at RIT.
His scientific contributions include Osipkov–Merritt models,[2] black hole spin flips,[3] the Leonard–Merritt mass estimator,[4] the M–sigma relation,[5] stellar systems with negative temperatures, [6] and the Schwarzschild Barrier.[7]
