About us

The Virtual Screening and Property Prediction group is part of the Digital Biologics Platform (DBxP) in Sanofi R&D. We develop and apply physics-based modeling, molecular simulation and machine learning workflows to support the discovery and optimization of therapeutic proteins (antibodies and nanobodies®). Be part of our team Computational Biophysics for Protein Property Prediction as an intern .

Job Description

Predicting protein properties such as stability and aggregation is an important part of developing protein therapeutics. Proteins are flexible molecules, and their conformational dynamics can affect how they behave in experiments. In this internship, you will investigate whether information from molecular simulations can help predict these properties, using in-house experimental data.

Your tasks :

• Set up, run and analyze Molecular Dynamics and Monte Carlo simulations of proteins, mainly antibodies and nanobodies.

• Calculate descriptors from the simulations (e.g. flexibility, conformational ensemble characterization, surface properties) and relate them to experimental data.

• Build a predictive workflow that combines simulation-derived descriptors with statistical or machine learning models.

• Benchmark publicly available prediction tools, including generative AI for structural ensemble prediction, against Sanofi in-house data.

• Present your results to computational and experimental colleagues and document the workflow.

Requirements & Qualifications

• You are currently enrolled in full-time in a master’s program in biophysics, computational chemistry, structural biology, bioinformatics, physics or a related field
• Mandatory internship of 6 months
• Experience with Molecular Dynamics and/or Monte Carlo simulations and classical molecular modeling (e.g. GROMACS, AMBER, OpenMM, Rosetta, Maestro, MOE, pymol, etc.)
• Programming skills in Python and experience working in Linux environments.
• Knowledge of protein structure, in particular antibodies or nanobodies, is a plus.
• Experience with AI or machine learning (e.g. scikit-learn, PyTorch, protein language models, structure prediction tools) is a plus.
• Curiosity, independence, structured way of working, good communication skills and enjoyment of teamwork.
• Fluent English, written and spoken
