Two AI postdoc or machine learning engineer positions for oncology research

Two AI postdoc or machine learning engineer positions for oncology research KU Leuven is an autonomous university. It was founded in 1425. It was born of and has grown within the Catholic tradition. Located at the Gasthuisberg campus in the picturesque city of Leuven, the Laboratory of Cell Stress & Immunity (Department of Cellullar & Molecular Medicine) and the Laboratory of Computational Oncology (Department of Oncology) are looking for two experienced researchers in machine learning for applications in personalized healthcare. The LoCO ( and CSI labs ( are young, dynamic teams that aim to integrate digital twins of biological systems in drug design and repositioning for patient stratification. We particularly focus on cancer and immune-related diseases. Website unit Responsibilities In this project, you will be developing AI solutions that combine machine learning with knowledge-based inference, validated by independent experiments and partially supervised by human-in-the-loop systems. A key question will be how agentic AI and foundation models can be correctly guided, such that our tumor micro-environment simulation accurately represents the world model. This is necessary for the AI-driven target identification to correctly guide the target selection for follow-up antibody design. Offering the right context and finding ways for experts to translate their domain knowledge into flexible and mineable formats for the recommender approach will be crucial. You will coordinate with other team members to ensure scalability of the workflow, while working in a secure environment that contains real‑world patient data. You will actively contribute to developing the heart of the next‑generation system for drug target recommendation and associated biomarker detection systems. You will join a consortium already building digital twins of biological systems, such as AI‑driven virtual cells (AIVC), while contributing to developing image‑based biomarkers (digital pathology) and AI‑based structural antibody design. For this task, a large data lake containing public and in‑house biological datasets on thousands of patients (e.g. single‑cell and bulk RNA‑sequencing, joint omics profiles, perturbation datasets for knock‑out and drug response, as well as clinical metrics) is available. You will leverage these existing datasets and tools to create an AI‑enabled simulation of the tumor micro‑environment to identify critical pathways in disease progression. Overall, the approach will result in a robust recommender system to select top candidate pathways and priority proteins for targeting with novel antibodies designed by our consortium. These will be validated in both mouse models and patient explants to ensure that our simulations align with the global model.
