Adrian Constantin

Adrian Constantin (born 22 April 1970) is a Romanian-Austrian mathematician who does research in the field of nonlinear partial differential equations. He is a professor at the University of Vienna and has made groundbreaking contributions to the mathematics of wave propagation. He was later educated at the University of Nice Sophia Antipolis (BSc 1991, MSc 1992) and at New York University (NYU), where he got his PhD in 1996 under Henry McKean with the thesis "The Periodic Problem for the Camassa–Holm equation". He did post-doctoral work at the University of Basel and at the University of Zurich. Since then he has been university professor for partial differential equations at the University of Vienna, and also had a chair at King's College London during the period 2011–2014.

Constantin specializes in the role of mathematics in geophysics using nonlinear partial differential equations to mathematically model currents and waves in the oceans and in the atmosphere. These flows and waves play an important role in the El Niño climate phenomenon and in natural disasters such as tsunamis. and the importance of the Coriolis force.
