Mariana Weissmann (born 17 December 1933) is a physicist from Argentina who specializes in computational condensed matter physics. In 2003, she became the first scientist from Argentina to receive the L'Oréal-UNESCO Award for Women in Science and was also honored with the Konex Prize in the field of Physics.

Work

Weissmann obtained her doctorate in 1965 at the University of Buenos Aires and pursued further postgraduate education at the California Institute of Technology. Her expertise lies in theoretical and computational modeling within solid-state physics.

Her investigations into the computational aspects of condensed matter, with a particular emphasis on ice crystallization, have played a role in enhancing cloud seeding methods designed to influence rainfall. Additionally, she explored the properties of silicon surfaces and their bonding with carbon atoms, including research on doped fullerene molecules.

Throughout her career, Weissmann has mentored many doctoral students and authored more than 100 research articles published internationally. The L'Oréal-UNESCO Award she received in 2003 in the Latin American category marked an important achievement for scientists from Argentina.
