Recognition
Grego was named as a Fellow of the American Physical Society (APS) in 2021, after a nomination from the APS Forum on Physics and Society, "for producing significant, highly influential technical and policy analyses of critical issues in international security and arms control, especially in the areas of missile defense, space weapons, and space security, and for sustained activities that have engaged and educated students, colleagues, policy makers, and the public about these issues".

She was the recipient of the 2023 Leo Szilard Lectureship Award of the APS, "for significant, influential analyses of critical issues in international security and arms control, especially in the areas of missile defense, space weapons, and space security; for sustained activities educating students, colleagues, policymakers, and the public about these issues".
