Two jobs, two countries, two homes

Yulij Il’yashenko is well known in the dynamical systems community for his work on the 16th Hilbert problem, generic properties of dynamical systems, and non-local bifurcations. He works part-time both at Cornell University in the USA and at Moscow State University, the Independent University and the Steklov Institute in Russia. Hinke Osinga asked him what it was like to grow up in the former USSR and how he has come to enjoy his life split between two continents.
