Profile

After graduating in Biochemistry (Univ. Lisbon, Portugal), Miguel did a PhD at the MRC Clinical Sciences Centre in London with Prof. Ana Pombo, where he studied the spatial organisation of the genome. He then joined Prof. Wolf Reik’s group at the Babraham Institute in Cambridge to investigate mechanisms of epigenetic regulation, and in particular the role of DNA hydroxymethylation in embryonic stem cells. In 2011 he was awarded a Next Generation Fellowship from the Centre for Trophoblast Research (Univ. of Cambridge) and joined the Blizard Institute (QMUL) in October 2013 after securing a Sir Henry Dale Fellowship from the Wellcome Trust and Royal Society.

Summary

Our group is interested in the epigenetic regulation of transposable elements and its impact on genome function. Almost half of the human genome is made up of transposons, and a proportion of these remain active and mobile. Therefore, their transcription needs to be tightly controlled to prevent mutagenic events. On the other hand, transposons have helped to drive genome evolution, often contributing with gene regulatory elements, amongst other genetic components. Our lab uses epigenomic approaches and molecular biology tools to investigate the epigenetic mechanisms involved in these two seemingly opposing facets of transposon biology. Our group aims to elucidate the functional roles that transposable elements play in the contexts of development, health and disease.

Research

Research Interests:

Control of TE expression

In most somatic tissues, TEs are transcriptionally repressed by a variety of mechanisms, including DNA methylation and histone modifications. We aim to better understand these mechanisms, and are particularly interested in cases where the epigenetic landscape is distinct to that seen in most somatic tissues, such as during preimplantation development. 

TEs as gene regulators

Non-coding sequences within TEs harbour multiple binding sites for host transcription factors. As TEs spread throughout the genome, some of these sequences can become important regulators of host gene expression. We aim to establish causal links between TE regulatory capacity, gene expression and phenotypes. 

TEs in placental evolution

The unique epigenetic landscape of the placenta presents an apparently permissive environment for TE expression, which may have led to an extensive co-option of TEs as placental genes and regulatory elements. We are dissecting the contribution of TEs to the enhancer landscape of both rodent and primate trophoblast.
