About Me

I am a PhD candidate at the Construction Management and Engineering Group, University of Twente. I am a civil engineer passionate about roads. Interested in the research of road infrastructure systems by analyzing processes that lead to more sustainable development.

I hold a bachelor’s degree in civil engineering and a master’s degree in civil engineering with an emphasis on road infrastructure from Universidad de los Andes, in Bogotá, Colombia. Before pursuing my master’s degree, I did an internship at CEMEX, a multinational building materials company. During this period, I provided support and assistance for the development of pavement design proposals.

While I was doing my master's, I worked as a Research Assistant in the construction management group of the Department of Civil and Environmental Engineering. During this time, I conducted studies related to sustainable practices focused on how to successfully manage and develop road infrastructure projects by applying system dynamics and decision-making approaches. After my master's, I kept working at Universidad de los Andes supporting a research project focused on evaluating carbon abatement strategies in the Colombian social housing sector. My experience has been fundamental to understanding the importance of analyzing infrastructure components from systemic perspectives if we want to find efficient solutions that contribute to the sustainability of the sector.  


Many innovations have emerged to reach sustainability targets in the road infrastructure sector. However, the sector is still struggling in the implementation of sustainable asphalt innovations. Efforts in the infrastructure sector are not unified and there is a challenge to align firms’ innovation trajectories with public clients’ policy targets. There is no consensus among stakeholders on sustainability values which prevents the efficient incorporation of asphalt sustainable innovations. My PhD research project seeks to develop a guideline for stakeholders to speed up the implementation of these innovations.

It aims to contribute to the understanding of the system behind the implementation of sustainable innovations in the asphalt sector, including the interactions among actors involved in the development of projects. For this, it will have an exploratory phase to identify the main factors that affect the implementation of the innovations and the dynamics among them. Following a Complex Adaptive System approach, a model to represent the relationships among the factors identified is built to understand the mechanisms behind the implementation of the innovations. The succeeding phases are focused on developing strategies that lead the asphalt sector to be more sustainable. The purpose is to identify actions to speed up the implementation of the innovations and share them with stakeholders through workshops.
