If it will be any use to you, the standard advice I give is something like this (I adapt as necessary--use anything of it you care to)
First, give the basic information--the source should be the CV-- birthplace and date, degrees, previous positions. If there are published books, list them in formal bibliographic style. In a field dependent on journal articles, list the 3 or 4 most influential articles, getting citation figures from Scopus or Web of Science or Google Scholar, or some other appropriate source.. Do not include conference presentations, book chapters, and other minor published work. Such a list needs to be frequently updated, and belongs in the CV, not an encyclopedia.
Include major national level offices and awards, but not minor ones. Be sure to list editorships (but not mere editorial board membership) --we consider it very important, and you should add it to the articles for the relevant journals also, with a link to the bio. If the person has any notable students who would qualify for Wikipedia bios, include them. Their PhD & postdoctoral advisors probably also qualify for bios here; add them and link them, even if they do not yet have articles.
It is not necessary to cite the basic information in detail to other than the official CV. However, give any actual references providing substantial coverage from 3rd party independent published reliable sources, print or online, but not blogs or press releases, or material derived from press releases. For any part you quote directly from a published bio, include quotation marks and a reference.
Pay particular attention to the way we make links to other Wikipedia articles. Avoid WP:Peacock terms: do not use words of praise, or state that the person is important: the contents of the article will show it. Include only material that would be of interest to a general reader coming across the mention of the subject and wanting the sort of information that would be found in an encyclopedia. Do not include material that would be of interest only to those associated with the subject, or to prospective students--that sort of content is considered promotional. Keep in mind that the goal of an encyclopedia is to say things in a concise manner, which is not the style of press releases or web sites, or CVs, which are usually more expansive.
And be certain never to use material copied from other sources unless it is in the public domain, or released to us under a free license Even when it might be possible to get permission, there is generally no point in doing so--a person's web site or CV is usually unsuitable for WP, because it is usually written to some degree as a press release, praising rather than describing the subject and containing material we would not include, such as a full list of every minor publication. It is therefore always better and much easier to rewrite. In doing this, remember to also avoid Close paraphrase. Rewrite from scratch, changing not just the words, but the arrangement into sentences and the sequence of ideas.
