Van Der Hoef & Partners vacatures

Do you have a strong background in machine learning, deep learning, and/or computer vision? Are you curious, independent, and motivated to push the boundaries of AI in a real-world, high-impact domain? Do you enjoy working in an interdisciplinary and international research environment, closely collaborating with other PhD students, clinicians, engineers, and industry partners?

We are looking for an ambitious PhD candidate to work on foundation models for oncology, embedded in the Foundation Models For Oncology (fomo.fo) lab, a collaboration between the Netherlands Cancer Institute (NKI), the University of Amsterdam (UvA), and Kaiko.ai. The position is part of the national NWO Perspectief FIND (Foundation Models for Industry) project.

Foundation models are transforming artificial intelligence by enabling transfer across tasks, data regimes, and application domains. In oncology in particular their potential impact is profound: from earlier and more accurate diagnosis to better treatment planning and longitudinal patient monitoring. However, current foundation models are largely optimized for language or natural images and struggle with the core challenges of medical data, including three-dimensional structure, multimodality, temporal progression, data scarcity, and strict privacy constraints.

This PhD project aims to contribute to a new generation of oncology-native foundation models that can robustly reason over complex multimodal medical data such as radiology, histopathology, and associated clinical information. The research will focus on developing scalable, transferable, and data-efficient learning strategies that move beyond narrow task-specific models and towards general-purpose representations of patient state.

The project is embedded in the national FIND consortium, which brings together multiple Dutch universities, research institutes, and industry partners to advance foundation models for underserved, privacy-sensitive, and application-critical domains. Within FIND, this PhD will specifically focus on the healthcare and oncology track.

What are you going to do?

As a PhD candidate in computer science, you will conduct fundamental and applied research on foundation models for oncology. Together with your supervisors, you will help shape the precise research direction. Your work may include, but is not limited to, the following activities:

• Developing novel foundation model pre-training and post-training methods for oncological data, 3D medical imaging, multimodal patient data, and longitudinal cohorts;

• Designing novel architectures and learning strategies that explicitly model spatial, temporal, and multimodal structure;

• Evaluating models on clinically relevant downstream tasks such as detection, segmentation, structured reporting, and disease progression modelling;

• Performing high-quality academic research at the intersection of deep machine learning, medical imaging, and oncology, with the goal of publishing at top-tier venues such as NeurIPS, ICLR, CVPR, and leading journals;

• Developing robust, well-engineered research code as part of a fast-paced and highly skilled team;

• Collaborating closely with clinicians and researchers at the Netherlands Cancer Institute, as well as academic and industrial partners within UvA, Kaiko.ai, and the broader FIND consortium, to ensure clinical relevance and translational impact;

• Regularly reporting on research progress and presenting intermediate and final results internally and at international conferences and workshops;

• Assisting in relevant teaching and supervision activities;

• Completing and defending a PhD thesis within the official appointment period of four years.
