I will give a brief summary of the most important dynamical processes
occuring in star clusters, as well as the reasons why we think we
should be looking for intermediate-mass black holes in them. I will
review relevant observational and theoretical results for this field
and I will present details about recent studies for omega Centauri and
M54. I will also discuss new results on photometric diagnostics for
the presence of IMBHs in globular clusters.
