Department of Computer Science (DIKU) invites applicants for a postdoctoral position in Computer Science. The position is part of the project Differentiable Realism from AI and Modeling (DREAM), financed by the Novo Nordisk Foundation.

Start date is (expected to be) 1 January 2027 or as soon as possible thereafter. The position is for either 1 year or 2 years.

The project
This postdoctoral project will develop general self-supervised and unsupervised machine-learning methods for biological data where reliable labels are scarce, expensive, or impossible to obtain. The aim is to build methods that use unlabelled experimental data together with differentiable simulations to generate realistic synthetic datasets, transferable representations, and robust downstream models without relying on large human-labelled datasets.

There is freedom to influence the project, and the exact direction of the project will be defined in dialogue with the candidate. Possible methodological directions include generative distribution matching, domain adaptation, diffusion- or score-based models for noise and style transfer, contrastive and masked self-supervised learning, uncertainty-aware learning, and few-shot adaptation.

The project is rooted in scientific machine learning, with biological imaging and biophysical simulation as driving testbeds. We work with data that range from chromatin organization to microorganism tracking. A strong candidate may come from machine learning, computer vision, generative modelling, scientific computing, simulation-based inference, or a related area.

Who are we looking for?
We are looking for highly motivated candidates with a PhD or equivalent research experience in computer science, machine learning, scientific computing, physics, applied mathematics, engineering, computational biology, or a closely related field.

Relevant experience may include one or more of the following:

• generative AI, including diffusion models / flow matching, GANs, VAEs, normalizing flows, or energy-based models
• self-supervised, unsupervised, or semi-supervised learning and representation learning
• contrastive learning, masked modelling, domain adaptation, or unpaired translation
• synthetic-to-real learning, simulation-to-reality methods, or few-shot adaptation
• differentiable programming, automatic differentiation, and optimization in JAX, PyTorch, or similar frameworks
• scientific machine learning, inverse problems, differentiable simulation, or physics-based modelling
• computer vision, biological image analysis, microscopy data, or other noisy high-dimensional scientific data

The successful candidate should be able to conduct independent research, formulate general methodological questions, write and maintain research software, and collaborate with researchers working on application-specific projects and experimental validation data.

Our section
The project will be hosted by the IMAGE section, which performs research in machine learning, computer vision, and simulation. The section is a part of the Department of Computer Science, Faculty of SCIENCE, University of Copenhagen. We are located in Copenhagen.
