Dr David Walker

Lecturer in Computer Science

School of Engineering, Computing and Mathematics (Faculty of Science and Engineering)

I currently undertake the following academic roles within the School:

  • Module lead (COMP3006 and COMP2002).
  • I am the Programme Manager for all of the programmes in the Computing undergraduate suite.
  • I am the Exam Coordinator for Computing modules.
  • I supervise a number of PhD students undertaking research in topics such as evolutionary computation and machine learning.

Qualifications

I received a BSc in Computer Science from the University of Exeter in 2007, and obtained a PhD in Computer Science from Exeter in 2013 for a thesis entitled "Visualisation and Ordering of Many-objective Populations". Between 2013 and 2018 I held postdoctoral research positions at Exeter, working on a range of topics relating to evolutionary computation and machine learning.

Professional membership

I am a member of the IEEE Task Force on Many-objective Optimisation.

I am a Fellow of the Higher Education Academy (FHEA)

Teaching interests

This year (2020/21) I am module leader for:

  • COMP2002 Artificial Intelligence
  • COMP3006 Full-Stack Development
I am supervising a range of final year projects.

Research interests

My research interests lie in the area of evolutionary computation and visualisation. My recent work has included:

  • Visualising sets of solutions to many-objective optimisation problems.
  • Visualising the operation and performance of evolutionary algorithms.
  • Interactive evolutionary computation for real-world engineering problems.
  • Data analysis within hydroinformatics (prediction and visualisation).
