Industrial PhD student in Machine Learning and Drug Design in Molecular AI

Project: Development of machine-learning methods to improve binding-affinity estimates

We are looking for an Industrial PhD student in Computational Drug Development to work on a project in a collaboration involving AstraZeneca Molecular AI Discovery Science Gothenburg Sweden Division of Computational Chemistry Lund University and the Foundations of Machine Learning group at KTH. This position is funded by DDLS (DataDriven Life Science / SciLifeLab).

The project: The industrial PhD student will focus on developing precision ML/AI models for rational small-molecule drug design. The overarching objective is to build physics-informed machine learning models for binding affinity prediction enabling generative models to design chemically plausible compounds and prioritize candidates from hit discovery through to lead optimization. To achieve this the PhD student will apply a range of computational approaches incorporating fundamental features derived from physics-based methods and integrating them with start-of-the-art machine learning techniques. This combined strategy aims to enhance predictive accuracy and efficiency and improve the quality of next generation drug candidates.
