Robert J. Nemiroff is an astrophysicist and professor of physics at Michigan Technological University. He earned a B.S. in engineering physics from Lehigh University in 1982 and a Ph.D. in astronomy and astrophysics from the University of Pennsylvania in 1987.
His research has focused on subjects such as gamma-ray bursts, gravitational lensing, and cosmology. He is especially well known as the cofounder and coeditor of Astronomy Picture of the Day (APOD), the widely loved NASA project that pairs striking space images with clear, engaging explanations.
As an author, Nemiroff writes from the rare position of someone deeply involved in both scientific research and public science communication. That combination gives his work an inviting style: grounded in real astrophysics, but always aimed at helping curious readers enjoy the scale, beauty, and mystery of the universe.
