Develops research related to concrete technology and its application in structures. It works on the development of special concretes, such as ultra high performance fiber reinforced concrete. The professor’s research covers computational and experimental studies both in the development of new concrete and in the application of the material in structural elements. She has a degree in Civil Engineering from the Federal University of Juiz de Fora (2016), a master’s and doctorate in Civil Engineering (Structures) from the São Carlos School of Engineering at the University of São Paulo (2019, 2023). Professor in the Structures department of the Faculty of Engineering at the Federal University of Juiz de Fora since 2022, she is a permanent professor in the Postgraduate Program in Civil Engineering at UFJF. Participates in several research projects, such as “Investigation of the thermomechanical behavior of cement matrices under high temperatures: Experimental tests and computational modeling”, “Artificial intelligence for analysis of steel-concrete composite structures” and “High-strength steel profiles (Fe-Nb) in high-performance steel and concrete composite structures for infrastructure works”. Main lines of research: 1) Fiber-reinforced concrete 2) Ultra high-performance concrete 3) Computational modeling of concrete 4) Development of special concrete using artificial intelligence.
