Charles D. Brown II is an American physicist and postdoctoral researcher at the University of California, Berkeley, studying many-body physics of ultracold atoms in optical lattices.

Brown is also a lead organiser of #BlackInPhysics week, a campaign to recognise and amplify the scientific contributions of Black physicists.

[3] During his undergraduate studies, he carried out a 10-week research placement at the University of Chicago supported by the National Science Foundation.

[9][10] Brown received the Leigh Paige Award (2013) and the D. Allan Bromley Fellowship for Graduate Research in Physics (2017) from Yale.

[14] In 2019, Brown joined the Department of Physics at University of California, Berkeley, where he studies ultracold atoms trapped in two-dimensional optical lattices.
