It depends on what type (and also whether you distinguish computational biology from bioinformatics). The people who create new algorithms for sequence assembly, protein folding, etc. tend to be computer scientists who got into biology. On the other hand, the people who analyze biological data computationally tend to be biologists who got into computing.

They are arguably computer scientists who do “bioinformatics” by building tools. Different skill set. Also not a large number of them.

Most bioinformatics jobs need domain specific bio knowledge.

Things will change even more as DNNs take over.
