There is a substantial body of knowledge about the theoretical capabilities of quantum algorithms, given ideal quantum computers, but this is quite far removed from what is needed to run on real quantum computers being built today. Collaborating with computational scientists to understand what their applications do is a key aspect of the project. This includes teams of academics and postdocs who are working on applications to fluid simulations (from weather forecasting to fusion) and materials simulations, and across the whole spectrum of scientific and engineering computing in the UK through the CCP-QC https://ccp-qc.ac.uk/ (Collaborative Computational Projects) network. You will be able to test your ideas on real quantum computers, and there is plenty of scope for choosing which aspects of the research you are most interested in.
