Alexander Georgievich Kosovichev (born July 3, 1953) is a Russian astrophysicist, scientist, researcher, and academic.

Kosovichev is distinguished professor of physics at the New Jersey Institute of Technology (NJIT), and has been the director of its Center for Computational Heliophysics since 2014.

[6] Kosovichev was born on July 3, 1953 in the town of Ishim, part of the Tyumen Oblast, in the Russian Federation.

After completing his studies there, he began his doctoral work in the field of solar physics at Moscow State University, where he got his Ph.D. in applied mathematics in 1980.

He joined Stanford University as a senior research scientist in 1994, where he worked at the W. W. Hansen Experimental Physics Laboratory.

This phenomenon is analogous to earthquakes on Earth and has helped scientists better understand the energy release mechanisms during solar flares.

Since joining NJIT in 2013, his work has been focusing on solar research through the establishment of the Center for Computational Helio-physics and his participation in major projects like Kepler, IRIS, SDO, and DKIST.
