We have a vacancy for a PhD candidate in machine learning at the Department of Computer Science (IDI), NTNU, Gjøvik. The position is a three-year full-time doctoral appointment and will be based at Gjøvik campus.

Are you motivated to take a step towards a doctorate and open up exciting career opportunities?

As a PhD candidate with us, you will work towards your doctorate in a strong international research environment and gain experience that supports a future career in higher education, research, or knowledge-intensive industry. 

The position reports to the Unit Leader of Colorlab.

About the project

The research will address the growing need for reliable methods that can assess the authenticity of visual media and provide understandable evidence for model decisions. The candidate will investigate how general-purpose pretrained visual and multimodal representations can be adapted for analysing authentic, synthetic, and manipulated images or videos.

The work will combine predictive performance with explainability, uncertainty estimation, robustness, and generalization. Attention will be paid to performance across datasets, content sources, generation methods, and real-world transformations such as compression, resizing, and re-encoding.

The final scientific scope will be refined together with the successful candidate and in dialogue with the relevant academic and external research environments.

Duties of the position

• Develop machine-learning methods for detecting, localizing, or characterizing synthetic and manipulated visual content.
• Study representations learned by large pretrained visual or multimodal encoders, including probing, adaptation, fusion, and efficient fine-tuning strategies.
• Design explanation methods that connect predictions to meaningful spatial, temporal, frequency-domain, semantic, or example-based evidence.
• Evaluate robustness and transfer to unseen datasets, content sources, and manipulation processes, including realistic post-processing and distribution shifts.
• Investigate uncertainty, calibration, and reliability measures that can support responsible human decision-making.
• Develop reproducible benchmarks and evaluation protocols covering predictive quality, explanation fidelity and stability, and computational efficiency.
• Publish results in peer-reviewed international venues and present the research at conferences, consortium meetings, and to interdisciplinary audiences.
• Participate in doctoral training, research-group activities, and collaboration with relevant academic and external research environments. 

Be prepared for changes to your work duties after employment.

Required selection criteria

• You must meet the requirements for admission to the IE faculty's Doctoral Programme, see Section 6-1 of the PhD regulations for more information.
• You must have a master's degree or equivalent in computer science, artificial intelligence, machine learning, computer vision, or signal processing. The degree must include a substantial independent project equivalent to a master's thesis.
• You must have a strong and relevant academic background from your previous studies and have an average grade from your master's degree study, or equivalent education, equal to B or better compared with NTNU's grading scale. Applicants with a weaker academic background may be considered if they can document that they are exceptionally suited for PhD education, for example through relevant work experience and/or peer-reviewed academic work.
• You must have good knowledge of machine learning and deep learning, with a sound understanding of experimental research methodology documented through coursework, projects, or publications.
• You must have strong programming skills in Python and experience with a modern deep-learning framework such as PyTorch or TensorFlow.
• You must have good written and oral English communication skills.

The appointment is to be made in accordance with NTNUs guidelines for recruitment positions for general criteria for the position.

Preferred selection criteria

• Experience with computer vision, video analysis, self-supervised learning, vision transformers, or multimodal learning.
• Experience with pretrained representation models, transfer learning, parameter-efficient adaptation, or representation probing.
• Knowledge of media forensics, synthetic-content analysis, manipulation localization, or related authenticity problems.
• Knowledge of explainable AI, uncertainty estimation, calibration, out-of-distribution detection, adversarial robustness, or causal analysis.
• Experience with causal inference, counterfactual explanations, or uncertainty quantification in deep learning
• Evidence of high quality scientific writing, publications, a strong master's thesis, research software, or relevant open-source contributions.
• Prior experience working across geographically distributed teams.

Personal characteristics

To complete a doctoral degree, it is important that you are able to:

• Show strong motivation for research and a willingness to engage deeply with challenging scientific questWork independently while contributing constructively to an interdisciplinary team.

• Communicate, present, and collaborate effectively, including explaining technical ideas clearly and presenting research results to interdisciplinary audiences and consortium partners.
   

Emphasis will be placed on personal qualities.

We offer

• Stimulating research tasks at the intersection of machine learning, visual computing, and explainable AI.
• A strong international academic environment with access to relevant research infrastructure and expertise.
• Opportunities for collaboration, professional development, and participation in leading scientific venues.
• An open and inclusive working environment with committed colleagues
• Working capital that can be used to implement the project
• Career guidance and follow-up during the PhD period
• Favorable terms as a member of the Norwegian Public Service Pension Fund (SPK)
• Free Norwegian language training at a basic level (A2)
