معرفی
Jan Sieber is a Professor in the Department of Mathematics and Statistics at the University of Exeter, United Kingdom, and an active member of the Centre for Systems, Dynamics and Control. His research bridges theoretical and applied mathematics with environmental science and engineering, focusing on critical transitions in complex systems. ORCID: 0000-0002-9558-1324; contact: J.Sieber@exeter.ac.uk.
His primary expertise includes nonlinear dynamics, delay differential equations, tipping points in climate and ecosystems, and continuation methods in experiments. He extends this work into applied mathematics, control engineering, numerical bifurcation analysis, pure mathematics, physical geography, environmental geoscience, mechanical engineering, and ecological applications, particularly examining instability mechanisms in Earth systems and biological networks.
Scientific recognition includes the prestigious EPSRC Fellowship supporting his work on complex system instability.
