There are sometimes people names in taxonomy, like Myotis keenii was names after Mr. Keen who contributed to discover the species. So, if you discover a species and someone else is constructing the scientific name and names you, it's clear. But when you discover a species and you publish it in a paper, can you propose a scientific name that contains your name? Has it ever happened, or is it considered an unhealthy practice?
The answer is that in general, self-naming is severely frowned upon in the scientific community, but the act itself is not disallowed.
There have been at least two instances of self-naming recorded in literature, as stated in John Wright's book The Naming of the Shrew, page 34, where Jules Bourguignat named a species of snail after himself as Ferussacia bourguignatiana. The naming was apparently very poorly received (being referred to as taxonomic onanism), although I was unable to confirm this by locating the original citation.
