Olek Osikowicz

Computer Science PhD Student

Hi, I am a 3rd year PhD student at the University of Sheffield, supervised by Dr Donghwan Shin and Prof Phil McMinn.

Since September 2023, I have been a member of the AI x Software Engineering and Testing (ASET) group, where I do my research on reliable and efficient testing for Autonomous Driving Systems (ADS). My work explores:

Applying Multi-Fidelity Bayesian Optimization (MFBO) for test scenario generation
Using latent-space representations to accelerate critical scenario discovery
Flakiness in simulation-based ADS testing

Ultimately, my goal is to make ADS testing more robust, scalable, and trustworthy.

Alongside my research, I work as a Graduate Teaching Assistant for the COM3523 Software Re-engineering module, supporting both undergraduate and postgraduate students.

For more details, you can find my full CV here.
