Dr David Walker

Biography

Role

I currently undertake the following academic roles within the School:

Module lead (ISAD260 and SOFT352).
I am one of two Admissions Tutors for Computing programmes.
I am the Exam Coordinator for Computing modules.

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

Teaching interests

This year (2018/19) I am module leader for:

ISAD260 User-Centred Interface Design
SOFT352 Client-Side Web Scripting

I am also contributing to:

AINT252 Computation Theory and Artificial Intelligence
AINT514 Computer Science Workshop
SOFT549 HCI, Web and Mobile Development

I am supervising a range of final year projects.

Research

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).
