- Profile
-
Eleni graduated with a Bachelor’s degree in Informatics and Telecommunications and a Master’s degree in Microelectronics from the University of Athens, before taking her DPhil (PhD) at Sussex, in Computer Science and Artificial Intelligence.
From 2004 to 2006 she worked at the University of Bern and from 2007 to 2009 at the Swiss Federal Institute of Technology Lausanne (EPFL). In 2009 she joined the University of Sheffield as Lecturer, where she is Professor since 2016.
- Research interests
-
Bioinspired Machine Learning, Neuromorphic Computing, Computational Neuroscience
Eleni and her team take inspiration from biological principles to design novel, machine learning techniques, and in particular reinforcement learning and reservoir computing methods. They also work closely with material scientists and engineers to design hardware that computes in a brain-like manner.
