Margiotta-Casaluci Lab






Welcome to the

Margiotta-Casaluci Lab

The aim of our research is to understand and predict the causal link between the perturbation of biological  networks and the manifestation of adverse drug reactions. 

Our current research efforts are mainly focused to elucidate the role played by drug-mediated immune and inflammatory responses in determining drug efficacy and safety in both "normal" and pathological conditions.

In parallel with the drug safety research, we are also interested in understanding the molecular mechanisms underlying specific behavioural phenotypes. Specifically, we study the causal links between chronic inflammation, brain health, and behaviour. This research aims at generating novel mechanistic understanding that can potentially support the identification of more effective therapeutic strategies for patients affected by behavioural disorders.  


From a methodological perspective, we integrate computational biology approaches, network biology concepts, and the zebrafish model to investigate important clinically relevant questions.

The Margiotta-Casaluci Lab is based at King's College London, School of Cancer and Pharmaceutical Sciences.

AOP development 

We provide custom-tailored Adverse Outcome Pathway (AOP)-development to support the identification of effective mode-of-action-driven chemical testing strategies.


Chemical risk assessment 

Thanks to our 13-year experience in mode-of-action toxicology, we can help you to decide cost-effective and scientifically sound strategies to facilitate the integration of advanced mechanistic considerations into the traditional environmental risk assessment (ERA) of pharmaceuticals and other chemicals. We also provide custom-made data visualisation strategies to facilitate inter-stakeholder communication and support regulatory decision-making.

Group Leader, Principal Investigator 

Senior Lecturer in Toxicology

Luigi is a Senior Lecturer in Toxicology, and Group Leader at King's College London with more than 15 years of experience in the study of mode-of-action-driven toxicology of pharmaceuticals and cross-species extrapolation. He earned his PhD in Environmental Toxicology from Brunel University London in 2011 ( sponsored by GlaxoSmithKline), under the supervision of Professor John Sumpter OBE,  working on the extrapolation of pharmacological and toxicological data between zebrafish, mammalian pre-clinical models, and humans. Luigi continued to develop his research interests in comparative pharmacology during a 4-year BBSRC/AstraZeneca-funded Post-Doc at AstraZeneca and Brunel University London, where he started his independent research group in 2015. In 2021, Luigi started a Senior Lecturer (Associate Professor) position at King's College London.

Ben Holmes.jpeg



Ben is data scientist and registered associate nutritionist interested in research areas such as human disease, nutrition, sports science and pharmacology. He joined the DEVINA team in January 2022, and since then he has been developing a novel and exciting data platform - integrated with intuitive data viz - that will become a reference tool for any stakeholder interested in the use of toxicity data to support regulatory decision making. 

Philip Marmon.jpg


PhD Candidate

Philip is PhD candidate, holding a 4-year BBSRC/AstraZeneca PhD studentship. His research is aimed at exploring the immune-mediated effects of Non-Steroidal Anti-Inflammatory Drugs (NSAIDs, such as ibuprofen, diclofenac, celecoxib), and at characterising the phenotypic relevance of NSAIDs-target interaction networks, beyond cyclo-oxygenases (COXs) inhibition. Before joining the Margiotta-Casaluci Lab at Brunel University London, Philip graduated in Biomedical Sciences at the University of Sheffield (UK) and gained industry experience working at Oxford Immunotec. 



PhD Candidate 

Ines is PhD candidate, holding a 3-year Isambard PhD studentship. Her research is aimed at characterising the relationship between gut inflammation and behavioural disorders, bridging zebrafish research, human-relevant experimental data, and clinical observations. Ines graduated in Environmental Health at the Polytechnic Institute of Oporto (Portugal), and earned her master's in Toxicology And Risk Assessment from Brunel University London (UK).


BSc Final Year Projects and MSc Dissertations

Salwa Zabir (Biomedical and Molecular Sciences MSc)

Investigating the immunomodulatory effects of environmental chemicals  

Salwa is the recipient of a prestigious Matt Wilson Scholarship, which provides added-value to a research project by enabling costly experiments to be performed that otherwise would not be possible.

Matthew (“Matt”) Wilson studied at King’s College London and obtained an MSc in “Biomedical and Molecular Sciences Research” in October 2011. He graduated with Distinction, ranked 2nd of 33 students, notably whilst undergoing treatment for cancer throughout his studies. T

We are honoured to be the recipient of this Scholarship and we  are committed to carry out outstanding research and ensure that Matt’s legacy lives on!
