PhD

University of Plymouth

The objective of the PhD is to get an estimate of the performance of current methods in detecting AD from the analysis of functional connectivity and also what modifications can be applied to these methods so that they can detect AD potentially earlier.

Research Fellow

Complete Ambient Assisted Living eXperiment (CAALYX)

Responsible for creating a business plan for the succesful exploitation of the project's Intellectual Property as well as the project's dissemination and exploitation activities. Also participated in the development of a proof of concept project to build a realistic demonstrator within virtual worlds (Second Life) as the main developer.

Apr 2005 - Apr 2008

Research Assistant

BIOPATTERN

Acting head of the Data Acquisition Task Force. Main developer of the BIOPATTERN web portal (biopattern.org). Also participated in activities to do with the organisation of a large collection of various medical datasets so as to provide safe access to a group of researchers from across Europe.

Dec 2004 - Jun 2005

Research Assistant

The Heart To Heart Project

Main developer of a piece of software that was to run in a mobile device performing cardiac and respiratory rate monitoring for infants suspected of Sudden Infant Death Syndrome.

My work involved the literature review and implementation of the set of algorithms most suitable for the monitoring purposes. The whole software was written in C++ for the linux environment and was also modified to run on a small embedded platform (the gumstix board) to act as a demonstrator.

Research Assistant

Technological Education Institute Of Athens

Participated actively in the research going on within the Medical Image and Signal Processing (MEDISP) Lab of the Medical Instrumentation Technology department. Also acted as a lecturer's assistant in computer programming modules relevant to C and C++. This work was also carried over to relevant teaching at a master’s course hosted by the Technical Institution of Athens and Brunel University through external contracts.

Skills

Skills

Linux User

I have been using Linux since Slackware 3.5 and i am confident with the concepts introduced by *NIX systems. While my personal favourite is Debian, i have been responsible for managing systems running Suse  (Web and DBMS server), Fedora (web, DBMS and file server for our research group) and Ubuntu.

Python Programming

I got involved into Python programming as an alternative to MATLAB and was really impressed by the simplicity and elegance of the language. I have since then used Python for various projects but so far nothing as large as what i have implemented with MATLAB or C++.   Projects that can readily be demonstrated include:   Parallel Implementation Of The Strogatz And Wattz Small World Network Phenomenon On Amazon's Elastic Computing: This demonstration was part of a talk that was given at the university of Plymouth on Amazon's Elastic Computing and Elastic Storage facilities and how these could be affecting scientific computing. The program uses Parallel Python to spawn a process over a number of Amazon Elastic Computing Instances, collect the results and visualise them. The program also uses the Networkx package.   A parser for AC3D files using PyParsing and PyVisual: Looking for a convenient way to load my own 3d Objects in a 3D scene, i implemented a parser for the AC3D format which loads and reconstructs a 3D model from a textual representation of its form. This program will feature as an example in the next release of pyparsing.

MATLAB Programming

Projects implemented in MATLAB's programming language that can be readily demonstrated:   Underwater Sound Propagation And Its Impact On Acoustic Communications Systems: This project is divided into two parts: a) The Underwater Sound Propagation Simulator: Essentially, the output of this part is the impulse response of an underwater channel given the geometric characteristics of the emitter, receiver and their relative positions in space. A modified version of the ray-tracing technique was employed. b) The acoustic communications system simulator: A full simulator including an information source, a convolutional encoder, a modulator, the propagation channel (taken from the USP simulator), a demodulator and a viterbi decoder. This project was used to extract plots of Bit Error Rates VS SNR and at various Emitter, Receiver configurations for my MRes final project.   A toolbox for the analysis and visualisation of functional connectivity networks of the brain: The toolbox contains full implementations of various network structure metrics (clustering coefficient, mean path length, energy, average connection density, cost and others) as well as various models for the construction of various networks such as lattice, small world, scale free and others. The toolbox is specifically targeted towards the processing of time series data such as those obtained via functional modalities such as EEG or fMRI. This project has been used throughout my PhD Dissertation for the study of functional networks of the brain.

C / C++ Programming

Projects Implemented Entirely In C / C++ that can be readily demonstrated:   Digital Image Processing (DIP): A "photoshop" application for medical images implementing a range of image processing techniques such as the application of windows, filtering in the space and frequency domains, image spectra, histogram equalisation and others. Developed as an MDI application using the MFC framework.   Three Dimensional Ultrasound Reconstruction: An application providing an intuitive interface for the exploration of ultrasonic volumetric images obtained via common (i.e non 3D) ultrasound heads. The project stemmed out of a more complex application involving segmentation and surface reconstruction due to medical specialists feedback on artefacts introduced by the rendering process. Developed using the MFC framework and OpenGL.   Tomographic Reconstruction: Implementation of the basic filtered back projection tomographic reconstruction algorithm with the objective of applying it to data obtained via a prototype tomographic device.

Interest

Photography has been one of my interests since an early time in my life. Other than this, i pretty much enjoy any sea related activities.

I am holding a Royal Yachting Association Powerboating Level 2, Intermediate and Safety Boat certificates as well as the Short Range Marine VHF and First Aid certificates (Which are anyway prerequisites for the Safety Boat certification).
