Predicting Cytotoxicity using Cell Painting data
We show that using Cell Painting data improved the performance of cytotoxicity models and we can further interpret descriptors related to nuclei texture, the granularity of cells, cytoplasm and cell neighbours and radial distributions among others. (

Predicting Mitochondrial Toxicity using Cell Painting and Gene Expression
We perform a detailed biological interpretation of Cell Painting features in the context of mitochondrial toxicity prediction. We further show that using Cell Painting, Gene Expression features and Morgan fingerprints significantly improves the applicability domain of structural models. (

Similarity-based merger models
Designing fusion models of morphology and chemical space using a decision boundary based on their distance to the training set to improve the prediction of biological assay outcomes. (

From Pixels to Phenotypes: Interpreting Cell Painting Features in BioMorph Space 
Developing a data-based standardized and comprehensive framework for understanding the complex features in the Cell Painting assay from a biological perspective. (


Using chemical and biological data to predict drug toxicity
In this review, we discuss the various sources of information that can be used to better understand and predict a compound's toxicity, safety or biological activity, including using biological data such as gene expression and cell morphology. (

Current projects 

Advancing the understanding of Cell Painting Representations
This work focuses on interpreting the Cell Painting numerical features using convolutional neural networks to predict toxicity assays such as proliferation, oxidative stress, apoptosis etc. 

Transfer learning from structure to Cell Painting: A case study for Drug-Induced Liver Injury
This work applies transfer learning/graph-based approaches to Cell Painting datasets for the prediction of Drug-Induced Liver Injury.

[New] PKSmart
Human PK prediction, using chemical structure, and animal data, to build interpretable PK prediction models. (Beta version:

[New] Using Predicted in vivo studies and in vitro assay data to predict Drug Induced Liver Injury
We are repurposing in vitro and in vivo data to predict organ-level toxicity with interpretable machine learning. (Beta version: Coming soon!)
