Ottoline Leyser aims to understand how plants adjust their growth and development to suit the environmental conditions in which they are growing. In particular, she is studying how plants change the number of shoot branches they produce depending on factors such as nutrient supply and damage to the main shoot. She is particularly interested in the roles and mechanisms of action of plant hormones such as auxin.

One of her discoveries — the auxin receptor — has helped to explain how hormone signals shape the response of a plant to its environment. She began studying the growth of shoots in the 1980s in Arabidopsis, which at the time was an emerging model for plant biology.

Ottoline was awarded a CBE in 2009 in recognition of her pioneering work in plant science. In parallel to her research, and in conjunction with the Royal Society, she collated Mothers in Science: 64 Ways to Have it All (PDF), a book that highlights how female scientists have successfully combined parenting with their research careers.
