Sir David Charles Baulcombe FMedSci FRS (born 7 April 1952) is a British plant scientist and geneticist. He was Regius Professor of Botany at the University of Cambridge (Emeritus since 2019) and is currently Biological Secretary and Vice President of the Royal Society. In 2026, Baulcombe was announced as the next Master of Trinity College, Cambridge.
David Baulcombe was born on 7 April 1952 in the United Kingdom, in Solihull, Warwickshire, (in England's Midlands), into what he describes as "a non-scientific family".
As a child growing up in England’s West Midlands, David Baulcombe developed a fascination for algae, mosses, and other ‘lower plants’, which eventually led him to study botany at Leeds before shifting his focus to molecular biology.
He received his Bachelor of Science degree in botany from the University of Leeds in 1973, and continued his studies at the University of Edinburgh, receiving his Doctor of Philosophy degree in 1977 for research on Messenger RNA in vascular plants, supervised by John Ingle.
After his doctoral research, Baulcombe spent the next four years as a postdoctoral fellow at McGill University from January 1977 to November 1978, and then at the University of Georgia until December 1980. He then moved to the Plant Breeding Institute in Cambridge (PBI) from 1980 until 1988 before joining the Sainsbury Laboratory in Norwich in 1988. In March 2007 he became the professor of botany at the University of Cambridge and in 2009 was elected as a Fellow of Trinity College, Cambridge. In 2009, the Cambridge professorship was renamed "Regius Professor of Botany": the first Regius Professorship created by Queen Elizabeth II.
Since 2024, David Baulcombe has been Biological Secretary and Vice President of the Royal Society. In 2026, Baulcombe was announced as the next Master of Trinity College, succeeding Sally Davies.
One of Baulcombe's major discoveries in 1999 with Andrew Hamilton was of small interfering RNA (siRNA) that is the specificity determinant in RNA-mediated gene silencing in plants. These small RNAs were subsequently discovered in animals and fungi as part of a process first described as RNA interference by Fire and Mello in 1996. Fire and Mello were awarded the Nobel Prize in Physiology or Medicine in 2006 for their work, although some have argued that Baulcombe was among those overlooked for that year's prize.
Following the discover of small interfering RNAs, the Baulcombe research group at the Sainsbury Laboratory helped unravel the importance of RNA silencing and small interfering RNA in epigenetics and in defence against viruses. More recently, siRNAs have been developed as drugs to treat diseases in humans.
Other interests of the Baulcombe group involve disease resistance mechanisms in plants through the actions of NB-LRR (NLR) proteins. These proteins act in pairs with one partner serving as a sensor and the other as a helper. Baulcombe and his then PHD student Jack Peart provided the first evidence for NLR proteins acting as a pair.
Baulcombe has been married to Rose Eden since 1976, and they have four children. His interests include music, sailing, and hill walking.
In June 2009, Baulcombe was knighted by Queen Elizabeth II in the 2009 Birthday Honours List, "for services to plant science".
Baulcombe has also received the following honours and awards:
1997 election to EMBO Membership;
2001 election as Fellow of the Royal Society (FRS);
2002 election as Member of the Academia Europaea (MAE);
2002 recipient of the Ruth Allen Award of the American Phytopathological Society;
2002 recipient of the Kumho Science International Award in Plant Molecular Biology and Biotechnology, awarded by the Kumho Cultural Foundation, Korea;
2003 co-recipient (with Thomas Tuschl, Craig Mello, an Andrew Fire), of the Wiley Prize in the Biomedical Sciences, awarded by the Wiley Foundation at Rockefeller University;
