About me

I am a Reader in the School of Computer Science and Engineering having served as Head of School from 2002-2019. I am a member of the Computational Vision and Imaging Technologies Research Group.

I received my BSc in Computer Science (1987) and MSc in Advanced Computer Science (1988) from Queen Mary University of London. Following my graduation I worked as a Knowledge Engineer on an AI assisted system (AICQS) for the support of UNISYS customer services (1988-1990) and as a Research Fellow on an SERC medical image interpretation project for the dynamic modelling of cancerous cells (1990-1992). The latter project initiated my interest in motion-based recognition and the analysis of visual behaviour. I received my PhD from Queen Mary, London in 1996 with a thesis on the development of parallel implemented artificial neural networks on DAP for motion-based recognition.

 At the University of Westminster I founded the Computational Vision Research Group (CVRG) in 1997. CVRG’s early work focused on the use of dynamic visual information in the modelling and interpretation of objects and events in a scene, based on recurrent neural networks, multi-view Kernel PCA models and data-driven models using minimum description length. This position was also argued through the publication of a bestselling monograph “Dynamic Vision: From Images to Face Recognition” (Gong, McKenna, Psarrou 2000).  In later years I worked on hypersprectral analysis for applications in cultural heritage, video annotation and unsupervised region extraction and abstraction. Most recently I have been involved with the development and evaluation of explainable deep learning models for image system performance and the metrification of image quality for automotive applications.

Throughout my career at Westminster I have been involved in the development of teaching and research strategy. During my tenure as Head of School I have successfully delivered change management through two University restructures. I have  University-wide experience in academic processes and have acted as a member of  a number of University and Faculty committees including: the University’s Research Committee (1997-2003), University’s Work Allocation Modelling Committee (2012-2018), University’s Curriculum Review and Innovation Committee (2016 – 2018), member of University’s Athena SWAN  SAT (2012-2018), elected member of Faculty’s Research Committee (2014-2018),  Chair of the Computer Science – Engineering Athena SWAN SAT (2017-2018), member of the School/Campus/Faculty Executive Group (1997-2018).  I serve as member of assessment boards and validation panels both externally and internally within the University of Westminster and I have acted as PhD external and internal examiner.  I am a reviewer for EU projects and Advanced HE panel member for Athena SWAN applications.

Teaching

Undergraduate and postgraduate teaching 

Over the last 25 years I have designed and taught modules that varied from introductory programming for level 4 and postgraduate students with no computer science background to subject specialist modules in computer vision, image processing, neural networks and deep learning.

Currently I am involved in the following modules:

5COSC003W Software Development Group Project (module leader)

This module features state-of-the-art methods in software engineering practices from a managerial, technical, and process perspective. Students gain their experience of model- based software development through the software cycle. They participate in a team work based on an incremental and iterative software development methodology, gain practical experience of various professional issues such as project documentation, professional Code of Conduct, or Professional ethics.

6CCGD002W Advanced Maths and Games AI (deliver 3 lectures)

The main focus of the module is to learn how to create an automatic random game world with metrics to generate human like intelligent behaviours primarily in non-player characters (NPCs). I cover lectures on reinforcement learning and deep reinforcement learning.

4COSC001W Programming Principles I (tutorials)

An introduction to computer programming in a high-level programming language. The module concentrates on teaching the fundamentals of programming and algorithm design. I deliver tutorials in Python.

My current research interest ficus on the the development and evaluation of explainable deep learning models for image system performance and the metrification of image quality for automotive applications.

My main areas of interest are:

  • Deep learning methods for Image Quality Performance
  • Explainable learning models 
  • Reinforcement learning  
  • Hyperspectral analysis and modelling of inks and paintings for cultural heritage
