    Agnes Le Port


    Agnès Le Port is a researcher at UMR MoISA and hosted by the National Institute of Nutrition (NIN) since August 2023.

    Epidemiologist in Public Health and Nutrition, her past research has focused mainly on the prevention of malnutrition in women and children in West Africa, through the evaluation of programmes and interventions focusing on maternal and child health and nutrition, nutrition education, nutrition-sensitive agriculture and social protection, using mixed methods approaches, combining both quantitative methods (randomized controlled trials, quantitative surveys) and qualitative methods (process evaluations).

    Since joining the IRD, her research focuses on nutrition transition, multiple forms of malnutrition (including overweight, obesity, micronutrient deficiencies and diet-related non-communicable diseases), food environments and, more broadly, sustainable food systems. In Vietnam, Agnès is particularly interested in studying   children and adolescents’ dietary behaviors, especially in relation to school food environments and school meals. More broadly, her research aims to identify, implement and evaluate interventions to improve the health of populations and promote healthy and sustainable diets.

    She is involved in the CGIAR initiative "Sustainable Healthy Diet Through Food System Transformation (SHiFT) as part of the Action Plan between France and CGIAR (2022-2024).


  • Alexis Drogoul, UMI UMMISCO
    Alexis Drogoul


    Alexis Drogoul (UMI UMMISCO, on assignment at Thuy Loi University) works on the design of Artificial Intelligence tools to assist in the modeling and simulation of complex systems, with a marked willingness to facilitation of interdisciplinary work and extraction of transversal concepts. Since 1991, he participates to the definition of some of the fundamental concepts of "agent-based modeling", while working on many thematic applications (in ethology, hydrology, geography, traffic…). In 1998, at the crossroads of computer science, experimental economics and participatory design, he works more specifically on participatory modeling and simulation approaches allowing to involve social actors in the design of models and particularly suitable to the management of conflicts for shared resources; they have been successfully applied in the field (in Bhutan, Vietnam, Thailand, Mexico). From 2005, he became the designer and one of the main architects of the modeling and simulation platform GAMA which aims to make available to non-computer specialists designing tools of spatially explicit models, multi-formalisms and multi-scales, and enable "smart" exploration (using simulation and optimization) of the area of their parameters. In the same time, thematic projects he is involved in for 10 years now, first in Hanoi and later in Can Tho and in Da Nang, are moving towards decision support in the policies of fight against environmental disasters (sea level rise and water salinization in the Mekong Delta, biological invasions, epidemiology of avian influenza, urban disasters).

    Research profile

  • Marine Herrmann, UMR LEGOS
    Marine Herrmann


    The research activities of Marine Herrmann ( UMR LEGOS) aim to improve our knowledge of regional marine systems. Her work uses modeling, satellite observations and in-situ measurements in order to understand the ocean circulation, its response to the different variability factors (anthropogenic, continental, atmospheric, oceanic...) and its influence on marine ecosystems.

    On assignment at USTH since October 2015, she develops, within the framework of HILO laboratory, a research project on the upwelling of Nha Trang. This upwelling is one of the key processes of ocean circulation in the East Sea, which develops in summer under the influence of the summer monsoon. This upwelling strongly influences the biological activity and therefore the fishery resources of the region. The questions relate to factors behind its strong interannual variability, to its long-term response to climate forcing and to the pelagic ecosystem response to this variability.
