No, it is not right. You can use a similar structure, but I would make some changes. Here are a couple of suggestions Having retired from his job my father feels a sense of loss Retirement has given my father a sense of loss" Retiring from his job has created a sense of loss within my father

Your sentence doesn't sound right to my ear for a few reasons, and having done a bit of investigation, I don't believe that having + past participle can ever be a subject. These options would work: "Retirement from his job has given my father a sense of loss." [subject is noun, "retirement"] "Having retired from his job, my father has a sense of loss." [subject is "my father", having retired is a participle verb form in an adverbial] See also: http://www.learnesl.net/past-gerund/ The resources about the use of the past gerund do not show it being used as a subject and I don't think that it would ever make sense to do so.

Yes, it's called a "noun clause". The gerund (having) begins it.
