Dissertation
In her dissertation, A History of Erosion in the Anacostia Drainage Basin, Williams sought to explore on the factors that eventually lead to the erosion observed in the Anacostia River. Little had been done in terms of examining the upper and lower regions of the river and the basin sedimentation. The flooding of Bladensburg, Maryland precipitated the erosion, and had caused the necessity for an investigation. She concluded that in addition to natural erosion, human activities including deforestation, agriculture and urbanization accelerated the process.

Williams spent most of her career teaching courses on geology and the social sciences. In addition to teaching and serving as chair of the Geology Department at Miner Teacher's College (1923–1933), she also taught at Howard University during the 1940s. She retired in 1955.
