This project will transform OpenML, a platform for sharing and creating datasets and AI models transparently and collaboratively, into a next-generation open science infrastructure.

To answer questions that look beyond individual entities, network science studies the interactions taking place in complex systems. These complex systems can often have temporal information on when an interaction occurs.

This thesis was embedded in the APELAFICO project and focussed on investigating effects of sound from North Sea offshore wind farms on pelagic fish and harbour porpoise.

PhD candidates carry out a programme of independent research and additional limited) course work, culminating in production of a PhD thesis in typically 4 years.
