Alice Kust Harding is an American astrophysicist at the NASA Goddard Space Flight Center, Greenbelt, Maryland.

[2] In 1980, Harding was appointed as astrophysicist in the Astrophysics Science Division at Goddard Space Flight Center, a post she has held since then.

Her main research interests have been high-energy particle acceleration and radiation processes in pulsars, highly magnetized neutron stars (magnetars), gamma-ray bursts, and supernova remnants.

[4] Harding was awarded the status of Fellow[5] in the American Physical Society,[6] after being nominated by their Division of Astrophysics in 1991,[7] for pioneering investigation of the theory of pulsar atmospheres, including the pulsar wind and its role in accelerating particles to high energies, and for contributions to the theory of basic electromagnetic interactions in the presence of super-strong magnetic fields.

[8] Harding was awarded the 2013 Bruno Rossi Prize together with Roger W. Romani for establishing a theoretical framework for understanding gamma-ray pulsars.
