Edith Heard, FRS, is a researcher in epigenetics. She is a Professor at the Collège de France, holding the Chair of Epigenetics and Cellular Memory, and since 2010 has been Director of the Genetics and Developmental Biology department at the Institut Curie in Paris, France.[3] Heard is noted for her studies of X chromosome inactivation.[4][5][6][7][8]

Education

Heard graduated with a Bachelor of Arts degree in Natural Sciences (Genetics) from Emmanuel College, Cambridge in 1986. She completed her PhD degree in cancer research in 1990 at the Imperial Cancer Research Fund Laboratory in London, UK.[9]

Academic Work

Heard's main areas of research include genetics, epigenetics and developmental biology,[2] in particular focussing on X-chromosome inactivation. X-chromosome inactivation was discovered by the British scientist Mary Lyon in 1961, and occurs when one of the two copies of the X chromosome present in female mammals is inactivated. Heard and her colleagues discovered that X chromosome inactivation happens not once, but twice, during development – first in all cells designated to building the placenta, then again in some cells sent off to build the embryo.[10][11]

Honours

In 2009 Heard received the Prix Jean Hamburger and the Grand Prix de la FRM in 2011. In 2013 she was made Fellow of the Royal Society in recognition for her discoveries in epigenetics.[1] Her nomination reads:

Heard has made several groundbreaking discoveries in epigenetics, through her studies on X-chromosome inactivation, the process of dosage compensation in mammals. Heard developed powerful single-cell techniques enabling the analysis of fixed and living embryos and embryonic stem cells. These led to one of her major discoveries, showing that X-inactivation is a highly dynamic process during early embryogenesis and revealing major differences in X-inactivation strategies in different mammals, from mouse to man. Heard has also performed pioneering work revealing that in addition to epigenetic modifications, chromosome organization and nuclear compartmentalization are important players in the initiation and maintenance of X inactivation.[1]
