Our research sits at the intersection of gene regulation, human evolution and population genetics. We are particularly interested in the role gene regulatory processes have played throughout human evolution and continue to play in giving rise to present-day human diversity, and the implications this has for the widespread adoption of personalised medicine. Because gene regulation is not easily predicted (at least for now!) from sequence-level data, we use multiple a combination of computational biology and functional genomics approaches to understand the means by which cellular mechanisms interact to regulate gene expression, and, under the action of natural selection, ultimately give rise to inter-species or population-level differences. Our work directly speaks to, and seeks to remedy, the lack of diversity and representation in human genomics today.

Currently, one of our main focuses is understanding the challenges of people in Southeast Asia, with a particular interest on the Indonesian archipelago and the interactions between Homo sapiens and other, now extinct, regional hominins, such as the Denisovans.

Ongoing research in the group makes use of multiple cutting-edge approaches, including induced pluripotent stem cells (iPSCs), massively parallel reporter assays (MPRAs), functional genomics assays at bulk and single cell resolutions and machine learning, bringing together multiple disciplines to address questions that cannot be tackled independently by any single one of them. We are also one of the few groups worldwide with an established record in generating iPSC lines from non-model organisms such as great apes.
