Job description

Bulk shipping plays a vital role in global trade, transporting commodities such as iron ore, coal, grain, and fertilizer. Unlike liner shipping, bulk vessels operate without fixed schedules or predetermined routes, requiring operators to continuously adapt vessel deployments and cargo assignments to changing market opportunities and operational constraints. These planning decisions are further complicated by a range of uncertainties, including weather conditions, port operations, and cargo-specific requirements. A critical but often overlooked challenge is the uncertainty associated with cargo hold cleaning and the associated inspection processes, which can significantly affect vessel schedules, operational costs, and emissions

SCRUB (Scheduling, Cleaning and Routing under Uncertainty in Bulk Shipping) is a 2-year research project that aims to develop novel mathematical models and decision-support tools that explicitly account for uncertainties related to cleaning operations, inspection outcomes, weather conditions, and other operational processes. The project will combine real-world industry data and close collaboration with a Danish bulk shipping company to develop advanced optimization and analytics methods that improve routing, scheduling, and fleet utilization decisions while enhancing the robustness of operational schedules in the presence of uncertainty.

SCRUB is funded by the Danish Maritime Fund and involves collaboration with leading shipping companies in Denmark.

Based in Copenhagen - consistently ranked among the world's most liveable cities - you'll enjoy a high quality of life, a safe and sustainable urban environment, and a thriving cultural scene. At the same time, you'll be part of a vibrant, interdisciplinary research community at one of Europe's top technical universities, known for its commitment to innovation, societal impact, and diversity.

Responsibilities and qualifications

As part of the SCRUB project, you will develop advanced optimization models and solution algorithms for robust scheduling and routing of bulk carriers under operational uncertainty. We are looking for candidates with:

• Strong expertise in mathematical optimization
• Experience with large-scale algorithm design and implementation
• Knowledge of decision making under uncertainty
• Ideally, some exposure to machine learning methods
• A passion for research and for pushing the scientific frontiers.
• A desire to work with real industrial challenges.
• Excellent programming skills.
• Good collaboration skills.
• Fluent in English, spoken as well as written.

As a formal qualification, you must hold a PhD degree (or equivalent).
