Jeanne Gang, a modern American architect, has been designing fantastic glass skyscrapers. This is really important in my opinion as a lot of modern glass towers look alike and are boring. Jeanne Gang uses the boring facade of a glass tower and turns it into something else.  Most of her tower works are actually still under construction but most should be completed by 2020. Gang also has designed quiet a few school buildings such as the entire campus of the California College of the Arts in San Francisco. Definitely one of the architects to watch over the next few years.
