If these words (found here) are to be believed, then the IMDB link is correct:
- "Alison Bingeman later went on, under various names (including Alison Beynan and Alison Lea Bingeman) to write some highly respected episodes for USA television dramas including Relic Hunter, CSI:Miami and Whistler."
This information matches the info on IMDB, although it might have been, in all likelihood, taken from IMDB in the first place. She doesn't have a Wikipedia page, though The Celestial Toymaker does ad lists her as the writer.
