How to model the impacts of pesticides and chemicals from local to global scale? 

This 18 months programmer position will implement a new modeling platform the Pangea-USEtoxGeo model that assesses the worldwide environmental and human health impacts of chemicals

You are motivated and committed, with experience in data science, programming and a mathematical or modeling background and/or interest. If you want to apply your skills to contribute to advance the understanding and prevention of chemical impacts on the environment and human health, this programming position offers a meaningful opportunity for you!

The job
The position is offered at the Section for Quantitative Sustainability Assessment (QSA) within the Department of Environmental and Resource Engineering (DTU Sustain). QSA offers a collaborative environment to spearhead development of methods and application of life cycle impact assessment and sustainability assessment of products and chemicals, evaluating their impacts on both human health and the environment. Your work will be part of the EU-funded TerraChem project, which aims to assess the terrestrial impacts of chemicals from soils to apex species: chemical pathways, effects and impacts on terrestrial biodiversity and ecosystem services and applications for better chemicals management.

The present programming position does not require specific knowledge in environmental sciences. It will implement the available Pangea  pilot model into a new prepared USEtoxGeo framework in Python. USEtox is the scientific consensus

model for impacts of chemicals on human health and ecosystem working at continental scale, officially endorsed by the United Nations Environment Programme (UNEP) Life Cycle Initiative and used by the European Commission Joint Research Centre. USEtoxGeo will be its high-resolution version with up to 100,000 watersheds, building on a pilot model called Pangea . The implementation of USEtoxGeo follows a modular design to maximize flexibility for future extensions and the underlying data structure is based on graph data structures. The development will be carried out in interaction with project collaborators who will provide the environmental models sides of the project. The position is full-time and based at DTU Lyngby campus, just north of Copenhagen.

You will create a Geospatial model, for which your primary tasks will include the following:

  • Apprehend the USEtoxGEO modeling framework.
  • Implement the Environmental Process Models of USEtox into USEtox Geo and link them to the spatial dataset of soil, air and up to 100,000 watersheds.
  • Program the solving of large sparse differential equation systems to efficiently solve the system and predict increase in concentration in each modeling cells.
  • Link resulting concentrations to exposures and effects on humans and ecosystems
  • Create geospatial interfaces for users to provide inputs, create and parametrize problem specific grids, display and interpret results.
  • Test the model on a series of emission datasets, starting with pesticides applications, persistent organic pollutants and/or household emissions.
  • Prepare a publication describing and documenting the model

Required qualifications
You should have a master’s degree in programming, in data science, applied mathematics, computational methods, environmental or health informatics or a similar degree within the scientific fields relevant to the topics covered above.

In addition, you must have several of the following:

  • Experience in coding in Python, preferably with scientific Python (Numpy, Scipy) and possibly use of graph data structures
  • Independent algorithmic thinking and problem-solving mindset with/without AI programming tools
  • Experience with numerical methods for solving partial differential equations in three dimensions
  • Basic knowledge of chemistry and mass balance relations and/or the willingness to learn
  • Optional experience with GIS in Python (geographic information system)
  • Optional experience with databases and web development
  • Optional experience with environmental modelling
  • Strong scientific skills and rigor
  • Good project management skills
  • Ability to both work independently and in a team

A strong motivation for science-based data research and its application to environmental impacts models, a collaborative team spirit and excellent communication skills in English are essential for a successful application.
