Usually, finding research opportunities can be a simple process. First, identify what your area of interest is. After that, I recommend reading a few papers and narrowing what specific aspect of that interest catches your attention the most. You can find professors at schools that align with your specialty of choice. By sending a few brief emails asking questions about authors' research, you can follow up with a request to have deeper involvement with what they do.
University of London has some fantastic opportunities for undergraduate and graduate level research.
