Graduated in 2002 from the National University of San Juan, Argentina. Subsequently, she completed her Ph.D. at the University of Alicante in 2008, having been awarded a scholarship through the International Cooperation Program with Latin America. In 2008, she joined as a Assistant in the Department of Physics, Systems Engineering, and Signal Theory (DFISTS) at the University of Alicante (UA), where she later held positions as Assistant Professor (2011-2016) and Contracted Doctor (2016-2021). She has been a lecturer at the university since 2021.

She is a member of the Astronomy and Astrophysics Group of the DFISTS and a member of the University Institute of Applied Physics to Sciences and Technologies (IUFACyT). Her research focuses on the study of the collisional processes of small bodies in the Solar System, which are applied to modelling the collisional evolution of populations such as the Kuiper Belt and Jupiter's Trojans. She has also investigated asteroid fragmentation and the formation of asteroid families through numerical simulations. Currently, she is involved in the NEO-MAPP project and the HERA mission.

She has undertaken brief pre-doctoral stays at CASLEO (CONICET; Argentina), the Institute of Astrophysics of Andalusia (CSIC, Spain), the University of British Columbia (Canada), and the Besançon Observatory (CNES, France). In 2010, she completed a 6-month postdoctoral stay at the Southwest Research Institute in Boulder (Colorado, USA), for which she received a grant from the Generalitat Valenciana. In 2023, she started a 6-month sabbatical stay at the European Space Astronomy Centre (ESAC, Madrid).

She has authored over 20 articles in JCR-indexed journals, with two notable contributions published in multidisciplinary journals such as Science and Nature Communications. She is a co-author of more than 50 communications at national and international conferences. She regularly serves as a reviewer for various scientific journals indexed in the JCR. She has supervised two Ministry of Education and Vocational Training collaboration grants. She has supervised 7 Master's theses, two of them in the ERASMUS+ program, and is currently co-supervising two doctoral theses in the IUFACyT Ph.D. program.

She is a member of the Spanish Society of Astronomy (SEA) and the Royal Physics Society. She is a member of the Investigation Team for the Hera space mission (ESA) and the Investigation Team for the DART space mission (NASA). She was a member of the Local Organizing Committee for the 7th Workshop on Catastrophic Disruption and the IV Meeting on Planetary Sciences and Exploration of the Solar System. She has also been a member of the Scientific Committee of the biennial SEA Meeting in 2018, 2020, and 2022.
Currently, she is the chair of the Planetary Sciences community in Spain.

In 2020, the asteroid 2000 GT109 was renamed (51023) BenavidezLozano by the International Astronomical Union, recognising her work in Planetary Sciences.
