Welcome to the IDEAS laboratory

The IDEAS lab (Intelligent Dependability Engineering for Adaptive Software laboratory) consists of a group of computer scientists based in Birmingham, UK. The group's main research topic has been on the intersection between Artificial (Computational) Intelligence (e.g., Natural Computation and Machine Learning) and Software Engineering, particularly related to fields such as Self-Adaptive Systems, Search-Based Software Engineering, Data-Driven Software Engineering and Intelligent Performance Engineering.

The group is currently recruiting highly-motivated and excellent Ph.D. students to work in one (or more) of the research fields above. Funding opportunities are available; please get in touch if you are interested. More details can be found at here.
