Neil Brockdorff (born 7 May 1953) is a British molecular biologist and geneticist renowned for his pioneering research on X‑chromosome inactivation (XCI) and epigenetic regulation in mammals. He has held senior academic positions at the University of Oxford and the University College London (UCL), where he serves as Professor of Developmental Biology and Director of the MRC London Institute of Medical Sciences. Brockdorff’s work has substantially advanced the understanding of how long non‑coding RNAs and chromatin remodeling complexes orchestrate dosage compensation and cellular differentiation.

Academic and research career
| Year | Position | Institution |
|---|---|---|
| 1980–1985 | Postdoctoral Fellow | University of Cambridge (Laboratory of Peter L. Jones) |
| 1986–1992 | Lecturer in Genetics | University of Oxford |

Brockdorff’s early work focused on transcriptional regulation in embryonic stem cells. In the mid‑1990s he shifted his research to the mechanisms underlying XCI, leading to the identification of several key factors involved in the silencing process.
Research contributions
X‑chromosome inactivation
- Discovery of Xist RNA (1996): Demonstrated that the long non‑coding RNA Xist is essential for initiating XCI in mouse embryos.
- Polycomb recruitment (2000): Showed that Xist recruits Polycomb repressive complex 2 (PRC2) to the inactive X chromosome, establishing a repressive chromatin environment.
- Chromatin remodeling (2004): Identified the role of the chromatin remodeler SMARCA4 (BRG1) in the spreading of Xist across the X chromosome.
Epigenetic regulation
- Elucidated the interplay between DNA methylation, histone modifications, and non‑coding RNAs in maintaining long‑term gene silencing.
- Developed chromatin immunoprecipitation (ChIP) protocols adapted for low‑input embryonic stem cells, facilitating genome‑wide epigenomic mapping.
Stem cell biology
- Contributed to the derivation of naïve pluripotent stem cells from mouse and human embryos, linking XCI status to pluripotent state transitions.
