Claire Voisin is a famous math expert from France.

She studies algebraic geometry. This is a way to study shapes using math. She looks at how shapes change and work. Claire has solved many very hard math puzzles. In 2002, she showed a big idea was wrong. This idea was called the Hodge conjecture. Solving this was a major feat. She also solved a puzzle about curves. People had studied this for over twenty years.

Claire has won many big prizes. She won the Sophie Germain Prize in 2003. In 2017, she won the Shaw Prize. She also won the Crafoord Prize in 2024. She was the first woman to win it. Claire was the first woman to hold a special math job at the Collège de France. She was also a speaker at a big math meeting in 2010. She belongs to many groups for great thinkers. These groups help share her math ideas with the world.

Claire Voisin is a famous mathematician from France.

She studies a field called algebraic geometry. This area of math looks at shapes using equations. She explores how these shapes change and how they work. Her work often focuses on things called Hodge structures and mirror symmetry. These ideas help us understand the deep rules of geometry.

Math experts often try to prove if a big idea is true. Sometimes, they discover that an idea is actually false. In 2002, Voisin did exactly this. She showed that a certain version of the Hodge conjecture was wrong. The Hodge conjecture is a very famous puzzle. It is one of the seven Millennium Prize Problems. These problems are so hard they each have a one million dollar prize.

Claire has spent her life solving very difficult puzzles. In 2007, she won the Ruth Lyttle Satter Prize in Mathematics. This was for her work on the Kodaira conjecture. She also solved a part of Green's conjecture. This specific puzzle had stayed unsolved for over twenty years. Other math experts had been studying it for a long time. Her work helped clear up a very old mystery.

She has received many important awards for her talent. In 2003, she won the Sophie Germain Prize. She won the Shaw Prize in 2017 along with János Kollár. In 2024, she became the first woman to win the Crafoord Prize. She was also the first woman to hold the Chair of Algebraic Geometry at the Collège de France. From 2015 to 2020, she held this important position there.

Many groups of great thinkers have invited her to join them. She is a member of the French Academy of Sciences. She is also part of the Royal Society. In 2014, she was elected to the Academia Europaea. She even joined the German Academy of Sciences Leopoldina in 2009. These groups allow her to share her discoveries with other scientists. Her life shows how math can help us see the world differently.

Claire Voisin is a highly influential French mathematician.

She specializes in a field known as algebraic geometry. This branch of mathematics uses algebraic equations to study geometric shapes. Voisin focuses on complex structures and how they behave. Her research includes variations of Hodge structures and mirror symmetry. These topics explore the deep connections between different mathematical shapes and spaces. She has also written several important books about Hodge theory.

Mathematical progress often happens by testing famous ideas. Sometimes, a mathematician proves that a long-held idea is actually incorrect. In 2002, Voisin achieved this by disproving a specific version of the Hodge conjecture. This conjecture applied to compact Kähler varieties. The Hodge conjecture is one of the seven Millennium Prize Problems. These problems were selected by the Clay Mathematics Institute in 2000. Each of these seven problems carries a prize of one million US dollars.

Voisin has also worked extensively on the Kodaira conjecture. This conjecture involves deformations of compact Kähler manifolds. In 2008, she received the Clay Research Award for her disproof of this idea. Her work on this topic helped change how mathematicians understand these manifolds. She also made a major breakthrough regarding Green's conjecture. This conjecture concerns the syzygies of the canonical embedding of an algebraic curve. Voisin solved the generic case of this specific problem.

Green's conjecture was a very difficult puzzle for the math community. Algebraic geometers had been studying this specific case for over two decades. Voisin's resolution provided much-needed clarity to the field. While she solved the generic case, the full conjecture for all arbitrary curves remains partially open. This shows that mathematical discovery is often a continuous process. Her work on these conjectures demonstrates her ability to tackle long-standing mysteries.

Throughout her career, Voisin has received many prestigious honors. She won the European Mathematical Society Prize in 1992. In 1996, she was awarded the Servant Prize by the Academy of Sciences. She received the Sophie Germain Prize in 2003. In 2017, she shared the Shaw Prize in Mathematical Sciences with János Kollár. Recently, in 2024, she became the first woman to win the Crafoord Prize in Mathematics.

Her professional achievements include several historic firsts. In 2016, she became the first female mathematician to join the Collège de France. She was also the first person to hold the Chair of Algebraic Geometry at that institution. She held this chair from 2015 to 2020. In the same year, she received the Gold medal of the French National Centre for Scientific Research. This is the highest scientific research award in France.

Voisin is recognized by many elite scientific organizations worldwide. She is a member of the French Academy of Sciences. In 2009, she joined the German Academy of Sciences Leopoldina. She was elected to the Academia Europaea in 2014. In 2016, she became a foreign associate of the National Academy of Sciences. She was also elected a Foreign Member of the Royal Society in 2021.

Beyond her research, Voisin has contributed to the global math community. She was an invited speaker at the 1994 International Congress of Mathematicians in Zürich. In 2010, she served as a plenary speaker at the Congress in Hyderabad. She also served on the Mathematical Sciences jury for the Infosys Prize from 2017 to 2019. Her academic life is deeply connected to many international institutions. Her work continues to influence the study of algebraic geometry across the world.
