About Me

Juliette Cortes is researcher at the University of Twente and PhD in water management from the Delft University of Technology (The Netherlands). Her PhD research was carried out in an intra-european set up in close cooperation with the Italian National Research Council, Institute for Geo-hydrological Protection (CNR-IRPI, Padua, Italy).

As MSc and PhD student, she participated in two European Projects. The Project DIANE-CM which had two case studies one in Hamburg (Germany) and London (UK). The CHANGES project which had four European study areas in mountain areas. She particularly focused on the Fella Basin in the Northeastern Italian Alps (Friuli Venezia Giulia).

In Colombia, she prepared consultancy and construction proposals for engineering projects with the public and private sector. As field engineer, her tasks included the construction of minor river bank protections at critical locations along main national highways. She also attended one flood emergency in La Mojana, Magdalena (Colombia) where she interacted with local people as first responders.

Her research interests are in the management and communication strategies of river systems. Her research activities have focused on supporting collaborative efforts and community based monitoring strategies using decision support systems that combined multi-criteria methods and fuzzy logic. She aims at applying user-centered design approaches for designing the required web-based tools in decision support.
