what is this movie?

Inthe last five years there is a movie . The main characters is a superhero/comic book character , some kind of doctor or professor . She wears a sort of steampunk outift with brown leather pants. I think shes a british actress. I think the title is something like Dr or Professor and the something or others.Long wacky title. She befriends a teenage girl and they have an adventure hunting monsters or soemething.
