Jobbannons

Join us in reducing underwater noise and protecting marine ecosystems.

Underwater noise from ships is a growing environmental concern. Both regulatory bodies and ship owners increasingly seek means to mitigate these emissions, which negatively impact marine wildlife. To support this decision making, there is a need for better tools that describe the noise emissions. This issue is especially urgent in the pristine polar regions, where diminishing ice cover is leading to an increase in ship traffic, while, unfortunately, our understanding of noise generation and propagation in ice-covered waters remains limited. We are offering two PhD positions that provide a unique opportunity to advance sustainable transport by developing innovative methods, tools, and insights into this crucial issue.

Project descriptions

• Novel methods for computational hydroacoustics

This project focuses on developing cutting-edge computational methods for underwater noise generation and propagation using the Lattice Boltzmann Method. This approach has the potential to overcome many limitations of existing numerical techniques. As a PhD candidate, you will be responsible for advancing this method and coding it (in C/C++ or Python) to simulate noise generated by ship propellers and other devices. A key goal is to explore fluid-structure interactions and acoustics in polar ocean conditions, where ice presence plays a significant role.

• On-board noise detection and monitoring tool

The second project aims to create a tool for detecting and monitoring underwater noise from within the ship. You will simulate noise radiation and analyze its correlation to measurable quantities on-board. The analysis is done in collaboration with Kongsberg, who will develop and conduct the measurements. You will also explore operational mitigation techniques, enabled by and in connetion with the monitoring tool.

About the division of Marine Technology

The positions are within the internationally recognized Division of Marine Technology at the Department of Mechanics and Maritime Sciences, which drives both fundamental and applied research in marine technology, covering areas such as ship design, subsea systems, and renewable marine energy. We support global industries and communities with solutions that minimize emissions, extend equipment lifespan, and promote safe marine operations. Our research focuses on numerical modeling (e.g., CFD, FEA, FSI, optimization, and machine learning), complemented by experimental work and real-life monitoring.

Our division collaborates closely with Swedish shipping companies, research institutes, and industry partners. Since 2002, we have hosted the Kongsberg University Technology Centre in Computational Hydrodynamics, a hub for long-term research and industrial method development. Our division also contributes to Master’s and doctoral programs, including the Mobility Engineering program and the Nordic Master in Maritime Engineering. We foster an open, collaborative environment with senior researchers, post-docs, and PhD students working together.

Major responsibilities

As a PhD candidate, you will conduct independent research and collaborate with colleagues at Chalmers and industry partners. Your duties include:

• Developing scientific concepts and sharing your findings both verbally and in writing.
• Taking advanced courses that align with your project and support your professional growth.
• Teaching or other departmental duties, comprising 10-20% of your work time.

The position is full-time for up to 4.5-5 years, depending on teaching and departmental work.

Qualifications

Applicants should hold a Master of Science degree (or equivalent, at least 240 ECTS credits) in Mechanical Engineering, Engineering Physics, Mathematics, High Performance Computing, or a related field, with a focus on fluid mechanics and CFD. You must have excellent English communication skills and the ability to work independently, take initiative, and collaborate effectively with multidisciplinary teams. Strong interpersonal skills are essential for interacting with both academic and industry partners.

Contract terms

This is a temporary, full-time position, with a maximum duration of five years.
