Sebastian Wieczorek received his MSc in Theoretical Physics from Adam Mickiewicz University in Poznań, Poland, in 1998 and his PhD in Mathematical Physics from Vrije Universiteit Amsterdam, The Netherlands, in 2002. After his PhD, he worked as a researcher at Sandia National Laboratories in Albuquerque, New Mexico, USA, for the Department of Energy and Lockheed Martin Corporation. He joined the University of Exeter in the UK in June 2006, first as a Lecturer, then as a Senior Lecturer and Associate Professor of Mathematics. In August 2014, Sebastian took up the position of Chair Professor of Applied Mathematics and Head of Applied Mathematics at University College Cork.

Sebastian Wieczorek specialises in nonlinear dynamics. He constructs differential equation models to describe how real-life systems evolve over time. He also develops mathematical concepts and techniques for analysing such models. His main focus is on instabilities - large and sudden changes in the state of a system caused by small disturbances. Examples of his research include:
(i) Tipping Points (Critical Transitions) in natural and human systems.
(ii) Multiple timescale (fast-slow) and non-autonomous phenomena.
(iii) Mathematical modelling in medicine and human health.
(iv) Nonlinear dynamics of semiconductor laser systems.
