Academic Profile

I obtained my Degree in Electrical Engineering by the Department of Electrical and Computer Engineering of the National Technical University of Athens and my MSc in Sound and Vibration Studies and my PhD in Audio Signal Processing from the Institute of Sound and Vibration Research at the University of Southampton. During 2010-2012 I worked on the design and implementation of computationally efficient algorithms in time-series modelling problems as a Postdoctoral Researcher at the Department of Economics of the University of Cyprus. Prior to that I worked as a Postdoctoral Research Fellow in the Institute of Sound and Vibration Research (ISVR) of the University of Southampton for the project Biologically  Inspired Acoustics Systems (BIAS) during which I conducted research on the experimental, analytical and numerical modelling of ultrasonic backscattering in air and on harnessing the echolocation sensory modality of bats and dolphins for the design of assistive technologies for the blind.

Current Research

As of February 2013 I am a Research Fellow in the project BIOSOUND – Biodiversity monitoring using smartphones: designing an acoustic system for intelligent birdsong analysis. The project is run jointly by the Department of Zoology (Biodiversity Institute) and the Department of Engineering Science (Machine Learning Research Group) at the University of Oxford. My research is focused on the design of species classification algorithms for field recordings of birdsong as well as on the development of mobile device applications and on the creation of web based citizen’s science platforms for the implementation of these algorithms in a crowd sourcing environment.
