Among the latest sanctions on Russia over its invasion of Ukraine are penalties aimed at President Vladimir Putin’s two adult daughters.

The eldest, Maria Vladimirovna Vorontsova, was born in 1985, and works as a pediatric endocrinologist and genetics researcher. She leads state-funded programs that have received billions of dollars from the Kremlin and are personally overseen by Putin, according to the U.S. Treasury Department.

Putin’s younger daughter, Katerina Vladimirovna Tikhonova, was born in 1986. In 2015, Bloomberg reported on a new $1.6 billion startup incubator and science center next to Moscow State University — to be run by Tikhonova.
