PhD position in big data analytics to support ecosystem-based risk management of marine ecosystems

Technical University of Denmark (DTU)

Denmark 🇩🇰

A PhD position on data science is available at the National Institute of Aquatic Resources at the Technical University of Denmark (DTU Aqua) from January 2022.  The position is part of two EU H2020 projects: MISSION ATLANTIC – Towards the Sustainable Development of the Atlantic Ocean https:\\ and BRRIDGE-BS – Towards a productive, healthy, resilient, sustainable and highly-valued Black Sea . The PhD must therefore actively contribute to the large international research network established in this project. The project work is primarily carried out in the Section for Oceans and Arctic at DTU Aqua in Lyngby.

Project description
Marine ecosystems are complex adaptive systems consisting of large networks regulated by the adaptive dynamics of their constituents. Interactions in the networks occur across different levels of ecological organizations (from individual, to population and communities), and are both directly and indirectly modified by environmental pressures. Spatial and temporal dynamics on all levels of ecological organization are emergent properties of these interactions and regulated by local environment conditions. These complex dynamics and structures are central to life on Earth, and are generally investigated using both direct observations and mechanistic modelling of selected biological and physical quantities. However, it remains of critical importance to identify and characterise the relevant scales of ecosystem interactions, the responses of those to pressures and provide indicators of ecosystem state including them in a coherent framework for risk assessment in support of resource management.

In the current PhD project, we plan to develop statistical frameworks based on machine learning approaches (e.g. deep-learning, Bayesian non-parametric models, reinforcement learning) to combine observations and data from general ocean models to:

  • Develop adaptive statistical models of marine ecosystems able to combine deterministic and stochastic temporal representations;
  • Identify and predict the spatio-temporal dependencies across specific ocean regions;
  • Assess the role of resilience for ecosystem dynamics;
  • Detect anomalies in very large spatio-temporal datasets of ecosystem state;
  • Determine the importance of uncertainties in data input and prediction of ecosystem dynamics;
  • Advance decision support tools for risk and vulnerability management in marine ecosystems.

Candidates for the PhD position should have a two-year master’s degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master’s degree.

We are looking for candidates with:

  • An excellent background knowledge and experience in handling and analysing large data (e.g. satellite and in-situ observations)
  • Proven skills on advanced statistical modeling
  • Ability to develop the project across disciplines (e.g. data science, marine ecology, oceanography, mathematics, etc.)
  • Flexibility concerning research stays abroad
  • Good communication skills in English, both written and orally
  • Ability to conduct research independently and problem solving skills
  • Strong interest in participating in an inter-disciplinary and international research environment
  • Willingness to contribute to a positive and inspirational work atmosphere

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the successful candidate is enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide.

Description of Oceans and Arctic at DTU Aqua, Technical University of Denmark
The research spectrum of the Section for Oceans and Arctic covers oceanography, population ecology, observation technology and the Arctic. The research into oceanography integrates biological, physical and chemical parameters’ interactions in the ocean, ranging from individual plankton to regional seas. We focus on understanding the key processes that govern the structure and function of pelagic food webs, as well as climate and ecosystem interactions with a strong focus on quantitative methods.

The purpose of DTU Aqua is to provide research, advice and education at the highest international level within the sustainable exploitation of living marine and freshwater resources, the biology of aquatic organisms and the dynamics of ecosystems as well as their integration in ecosystem-based management. DTU Aqua has ca. 260 employees, of whom a third are scientific staff. The other employees are assistant biologists, laboratory technicians, IT employees, administrative staff, ship’s crew, student assistants etc. The institute is organized into eight scientific sections that carry out the research, educational and advisory activities. In addition, the institute has a number of scientific and administrative support functions, including the research vessel DANA. DTU Aqua has employees in Kgs. Lyngby, Silkeborg, Nykøbing Mors and Hirtshals as well as on Dana.

Technology for people
DTU develops technology for people. With our international elite research and study programmes, we are helping to create a better world and to solve the global challenges formulated in the UN’s 17 Sustainable Development Goals. Hans Christian Ørsted founded DTU in 1829 with a clear vision to develop and create value using science and engineering to benefit society. That vision lives on today. DTU has 12,900 students and 6,000 employees. We work in an international atmosphere and have an inclusive, evolving, and informal working environment. DTU has campuses in all parts of Denmark and in Greenland, and we collaborate with the best universities around the world.
