Postdoc Position Revealing Urban Waste Dynamics from Images with AI

Are you passionate about AI, urban sustainability, and real-world impact? Join the "Clean Inner City" initiative as a postdoc and revolutionize urban waste management in Amsterdam!

Job description
The city of Amsterdam is actively developing new policies and pilot projects to transform how it manages urban waste. In collaboration with AMS (Amsterdam Institute for Advanced Metropolitan Solutions), the city seeks innovative solutions to tackle the growing issue of waste and litter, particularly in its city center. To support this effort, the AMS Institute and the Municipality of Amsterdam have launched the “Clean Inner City” project to create, test, and evaluate advanced solutions for sustainable urban waste management. 

This postdoctoral position, funded under the "Clean Inner City" initiative, focuses on developing a smart sensing and monitoring system to better understand urban waste dynamics in Amsterdam. This includes but is not limited to, identifying entry processes of plastic (and other types of) waste into the environment from images, describing transport and retention processes in urban water systems, and exploring key explaining variables. The postdoc researcher will work on (1) collecting images at relevant study sites in Amsterdam, (2) designing and training AI-based models using deep learning, and (3) identifying and classifying the waste into different categories and exploring its transport dynamics in urban environments.

Key tasks of this postdoc position include:

• Developing a camera-based AI system to collect images at several field sites in Amsterdam.
• Collecting and curating image data (e.g., street-view images, hydrometeorological images) and potentially generating simulated datasets.
• Developing and training specialized deep learning models for waste-objects detection, classification of different waste types, and identifying waste patterns and actors contributing to these waste patterns.
• Collaborating with interdisciplinary teams and stakeholders to integrate the AI model into a real-world waste monitoring system. 

The postdoc will be based in the 3D Geoinformation research group in Delft, and it is a joint position with the River Plastic Team of the Hydrology and Environmental Hydraulics group at Wageningen University & Research (WUR). The candidate will be supervised by Dr. Liangliang Nan (TU Delft), Dr. Tim van Emmerik (WUR), and Prof. Jantien Stoter (TU Delft). You will be expected to spend 1-2 days per week at WUR and/or AMS, but this is open for discussion and may be subject to change depending on the project needs and the candidate’s interest.

Job requirements
You should have:

• a PhD degree (or can be expected in the coming months) in computer science, artificial intelligence, environmental science/engineering, civil engineering, geosciences, or a related discipline.
• passion to work on an emerging research topic with high societal relevance.
• interest and expertise in object detection from images and/or classification using deep learning, preferably with a strong publication record. Experience in plastic (or waste in general) detection or classification is a plus but not mandatory.
• affinity and motivation to plan and conduct (field) experiments in the Netherlands.
• demonstrated enthusiasm and proficiency in working with (complex) observational datasets.
• good command of English (oral and written).
• excellent programming (Python or/and C++), communication, and presentation skills.
• affinity with working in multi-disciplinary teams across institutes in an internationally oriented environment.
• enthusiasm and ability to publish research results in peer-reviewed academic journals/conferences.
