Like Roger Arliner Young, Williams was mentored by African American biologist Ernest Everett Just. Williams earned her bachelor’s degree in geology from Howard University in Washington, D.C. in Just considered Williams for a position at the University but chose to The sensitivity of such basins to climate change is analyzed using a physically based model of drainage basin evolution.
