Márcia Cristina Bernardes Barbosa is a Brazilian physicist. Born in Rio de Janeiro, Brazil, did her high school at Colégio Marechal Rondon in Canoas, Rio Grande do Sul, Brazil, undergraduate and graduate studies at the Universidade Federal do Rio Grande do Sul (UFRGS), Porto Alegre, Brazil.

 

After getting her PhD she spent two years as a postdoc at the research group of Michael Fisher at the University of Maryland. Back in Brazil she got a permanent position at the UFRGS where she is working until today., as Full Professor of Physics. She is a researcher with publications, thesis advised and organization of schools and international conferences.


A molecule of water – two parts hydrogen, one part oxygen – seems simple enough, but the properties of this mysterious substance have baffled scientists for generations. Throughout her career, Barbosa has sought to unlock the secrets of water’s anomalies, initially from a theoretical perspective and then by focusing her insights on practical applications for medicine and the life sciences.


Barbosa's work has helped explain why many characteristics of water – the motion of its molecules, its reaction to changes in temperature and pressure – make it different from other liquids in vast and important ways, and how biomolecules such as DNA, proteins and fats interact with water within the human body. She has furthermore developed a series of models about the properties of water that have contributed to our understanding of water’s interactions with biological molecules and geological processes.


In 1998 she became involved with the gender issue in physics. She worked as chair of the International Union of Pure and Applied Physics Working Group on Women in Physics. This group organized a number of conferences on women in physics. In 2008 she became vice-president of the Union of Pure and Applied Physics and director of the Instituto de Física da UFRGS. For her activities on gender issues she was awarded with the 2009 Nicholson Medal given by the American Physical Society.


Barbosa was named 2013 L'Oréal-UNESCO For Women in Science Awards Laureate for Latin America.
