Post-Doctoral Research Associate in Environment
Ecole des Ponts et Chaussées
École des Ponts ParisTech, created in 1747 under the name École Royale des Ponts et Chaussées, is a higher education establishment that trains engineers to a high level of scientific, technical and general competency. Apart from civil engineering and spatial planning, historically the source of its prestige, the School develops high-quality programs and research associated with the energy transition.

This post-doctorate will be carried out within the framework of the European project LIFE ARTISAN (Increasing the Resilience of Territories to climate change by encouraging Nature-based Adaptation Solutions, https://www.ofb.gouv.fr/le-projet-life-integre-artisan). ARTISAN is coordinated by the French Office for Biodiversity and proposes to support the 2nd National Plan for Adaptation to Climate Change (PNACC-2) by strengthening the incentive for the implementation of Nature-Based Adaptation Solutions (NbAS) in France. In this context, the HM&Co laboratory of the Ecole des Ponts ParisTech is in charge of research and teaching actions related to the evaluation of the performance of these Nature-based Solutions. This post-doc offer is mainly interested in the impact of NbaS to mitigate heat islands in urban areas. It is particularly focused on: (i) modeling and instrumentation of thermal-hydric flows in urban environments, (ii) development of training modules dedicated to this topic, (iii) evaluation of NbAS performance using a grid of indicators.
Thermo-hydric modeling to simulate the attenuation of heat islands
The main part of this post-doc is the participation to action C3 “Design and provision of technical resources” in which the ENPC has to contribute to the development of decision-making tools for the choice and design of NbaS in (peri)urban areas. For this objective, it is expected to deepen the coupling between the Multi-Hydro and Solène-Microclimat models carried out within the framework of the ANR EVNATURB project. Applied at the development project scale, this coupled model simulates the water and energy balances of the surface, and thus makes it possible to evaluate the performance of NbaS both in rainwater management and in heat islands mitigating. Beyond an improvement of the numerical scheme, an evaluation protocol will be implemented to ensure the proper functioning of the coupling, and to validate its outputs using experimental data. This protocol will be implemented on (at least) one urban pilot site of the ARTISAN project.. Several tracks are also considered to improve the coupling: (i) taking into account humidity near the ground, (ii) representation of particular SafNs (e.g. trees, valleys), (iii) translation of model outputs into performance indicators. In parallel with this modeling work, experimental campaigns (energy balance) will be implemented in order to obtain validation data.
Scientific enhancement through teaching modules
This second part of the post-doc concerns the C4 action “Development of initial training and continuing education”. On the basis of an inventory carried out on the existing training offer and on the development of a first multidisciplinary module, it is planned to meet the teaching needs relating to NbaS in urban cooling by structuring, valuing and disseminating the knowledge acquired during the ARTISAN project. To do this, a specific initial and continuous training module adapted to various levels of study (from Bac+2 to Bac+5) will be developed and proposed to interested establishments..
Evaluation of the indicators grid
Finally, this will involve working specifically on the C2B action “Monitoring and evaluation practices: appropriation of indicators and collection methods, evaluation of the quality of the protocols”. This will consist in implementing and analyzing a survey relating to the use of the grid of indicators developed during the 1st phase of ARTISAN (https://www.ofb.gouv.fr/sites/default/files/2022-06/ARTISAN_D4_R%C3%A9f%C3%A9rentiel_vf.pdf), and in particular those relating to urban cooling. This questionnaire will focus on the following 3 points: (i) Implementation of NbaS project monitoring indicators, (iii) Relevance of NbaS project monitoring indicators, (iii) Appropriation of NbaS project monitoring indicators.
In addition to these activities, the post-doctoral student will participate in project coordination and follow-up meetings. The writing of scientific papers and participation in conferences highlighting the work carried out will be strongly encouraged.
