Susan Bernal


Susan Andrea Bernal López is a Colombian materials scientist who is Professor of Sustainable Construction Materials at the University of Bath. Her research considers design, development and characterisation of novel cements and concretes. She was awarded the 2020 Institute of Materials, Minerals and Mining Rosenhain Medal and Prize.

Early life and education

Bernal was born in Bogotá, Colombia. She was an undergraduate and postgraduate student at the University of Valle, where she worked on alkali-activated cements. Specifically, her doctoral research considered the carbonation of concretes that are based on alkaline activated slag. She worked with Ruby Mejía de Gutiérrez, a Professor of Materials Science, on a number of papers and they registered a patent together. During her doctorate she carried out two internships, one supported by the United States Department of Energy to work at the Argonne National Laboratory, and one at the University of Melbourne.

Research and career

After graduating, Bernal moved to Aarhus University, where she spent a year as a postdoctoral fellow at the iNANO Instrument Center of the University of Aarhus.
In 2010, Bernal moved to the University of Melbourne, where she continued to work on geopolymers. Bernal was appointed as research fellow at the University of Sheffield in 2012, where she investigated alternatives to conventional cements and concretes. Concrete is one of the world's most popular building materials, and contributes to five to eight percent of global carbon dioxide emissions. She was made a lecturer in 2015.
In 2018, Bernal moved to the University of Leeds, where she continued to develop novel cements and concretes that are more sustainable and durable. In particular, she made use of natural clays and industrial waste. She joined the University of Leeds as an academic fellow and she became a professor there in 2019. In 2024 she relocated to the University of Bath, as a Professor in the Department of Architecture and Civil Engineering. Since the start of 2025, Bernal has been a part of numerous research papers, writing alongside some of her old colleagues from th University of Leeds. She took part in a paper called "Structural Alterations in Alkali-Sulfate-activated Slag Cement Pastes Induced by Natural and Accelerated Carbonation". This paper was published by Science Direct in their January 2025 issue, and was written alongside and, who were also employed at the University of Leeds.
