Biography
Dr. Andrew Keane completed his undergraduate studies in Australia and Germany before beginning a PhD at the University of Auckland in New Zealand. Upon completing his PhD in Applied Mathematics in 2016, he became a postdoctoral researcher at the University of Auckland. Since August 2019, Dr. Keane is a lecturer in applied mathematics at University College Cork in Ireland. His research expertise lies in dynamical systems and applying its techniques to systems from various areas of application, in particular climate systems.Research Interests
Dr. Keane is interested in the application of dynamical systems theory to areas beyond mathematics and actively embraces the cross-fertilisation between disciplines. So far he has studied systems in the context of neural networks, electro-chemical oscillators, climate systems, evolutionary robotics and control theory. Methods and tools from dynamical systems have the ability to unravel complicated behaviour, allowing one to potentially explain, understand and predict important physical phenomena. Key topics of Dr. Keane's research are climate dynamics, delay differential equations, bifurcation theory and coupled oscillators.
