Speaking on her announcement, Charlotte said, "I am especially excited to be involved in such a pioneering franchise for women's para-sport at the University of East London.
"The Phoenix has enabled me to continue my journey with UEL and seize a unique opportunity alongside a group of talented and inspiring women."
The East London Phoenix will make up one of four teams in the inaugural Women's Premier League.
Based at the University of East London's Docklands campus, the Phoenix slots into the High Performance ethos of the University and it is hoped that a mix of players and elite facilities will help improve the standard of the game in East London.
Director of Sport James Kilden said, "We will have a range of players, from the top GB Pathway athletes that are looking to play internationally, to those developing and looking to kick on in the sport."
UEL currently host a range of athletes on the High Performance programme and the addition of the Phoenix will help increase the number of wheelchair basketball athletes making use of perks such as specialist strength and conditioning sessions.
High Performance manager Will Ashby added, "We're hoping that the Phoenix will allow young athletes to take advantage of high level sporting guidance and give them a chance to play alongside experienced players in the world's first ever professional league."
