Dr. Stephen Power is an Assistant Professor in the School of Physical Sciences.

He is involved in the development of new modules for the Physics with Data Analytics programme, which is part of the larger DCU Futures Initiative.

His own research is in the field of theoretical condensed matter physics, with a focus on the electronic, spin and valley properties of two-dimensional materials and heterostructures.

Before joining DCU in 2021, he received a Ph.D. in Physics from TCD in 2012 and worked as a researcher and lecturer in Denmark, Spain and Ireland.
