Post Query for Tags

I would like to query posts that are in a category and tagged with a two specific tags. I’ve searched codex and the forums for this, and I’m having trouble finding information on it.

I’m currently using:

<?php $my_query = new WP_Query('category_name=Education&orderby=title&order=asc&showposts=100');

…to query posts in the Education category.

Is there a way to do a query for posts in a category and tagged with several tags?

Any help is greatly appreciated, thanks!
