What we do

Quality control of new cells, tissues and organs

Led by George and Dorian

We aim to automate the quality control of lab-grown cells, tissues and organs with single-cell and spatial resolution. This is important for both models of rare disease and transplantation.


Collaboration with Prof Kurian and Prof de Coppi.

Rapid skin sheets for gene therapy

Led by Vignesh and George

We aim to accelerate the growth of engineered epithelial grafts for skin rare diseases while preserving their self-renewal properties.


Co-supervise with Prof Li and funded by the MRC.

Natural history of micronutrient deficiencies

Led by Jas

We aim to understand the pattern of local adaptation to micronutrient deficiencies (Selenium, Zinc, Iron and others) as humans migrated around the world. These deficiencies are a global health burden worldwide and particularly prevalent during pregnancy and early childhood.

Determinants of iPSC differentiation success

Led by Pau

We aim to understand which factors drive the success of iPSC models of development or rare disease. As it happens, the in vitro accumulation of deleterious variation likely plays a major role. See bioRxiv manuscript.

Severe pre-eclampsia: molecular causes and consequences

Led by Dorian, Yara, Jose and Leysa

We aim to unveil the molecular underpinning of pre-eclampsia, which has no treatment and only resolves upon delivery. We apply single-cell and spatial transcriptomics to interrogate the maternal-fatal interface throughout gestation as well as interrogating potential infections.

Co-supervised with Associate Prof Hillman Dr Kristiansen and Prof Sebire. Funded by the MRC.

Manuscript in preparation.

Childhood Leukaemias: treatment, resis-tance and CAR-T targets

Led by Ilaria, Eduardo and George

We aim to profile resistant cells in CML and AML at single-cell resolution, including the transcriptome, surface proteome and driving mutations. We also test CAR-T properties as well as their life cycle, from infusion to expansion. See bioRxiv manuscript.

Mainly supervised by Assistant Prof Giustacchini. Funded by TAS, AMS (to Giustacchini) and the GOSH BRC.

Assessing Genomic Risks in gene therapy

Led by Dimah

We aim to provide quick and robust measures of viral vector integrations in patients undergoing gene therapy. We apply highly optimised capture and enrichment approaches, followed by stringent computational analysis. It is applicable to natural infections.

Co-supervised with Dr Williams and funded by KACST.

B6-dependent epilepsies

Led by Fatimah

We aim to investigate different childhood epilepsies responsive to B6 treatment using Mass Spec approaches.

Mainly supervised by Prof Mills and funded by KFMC.

Manuscript in preparation.
