Williams entered Rice University in 1966 and started out as an English major but during her junior year, she took a
political sociology course with
Chandler Davidson and she wrote a 50-page research paper on civil rights and the voting act in the context of East Texas politics. Impressed with her work, Davidson encouraged her to undertake graduate training, which she pursued at the
University of Chicago, where she won a highly-acclaimed Woodrow Wilson fellowship and earned a master's degree in 1973 and a doctorate in 1977, both in political science. While her time at Rice University was very fruitful, there were moments when she faced adversity and racism. Williams told
Sallyport (Rice University’s Magazine predecessor) in a 1988 interview, “It was the loneliest I had been in my entire life”. She also stated how she often had to explain to her white friends why she hated them having a
Confederate flag hanging in their living room. Williams joined the faculty at Howard University in 1977 and taught courses in political science. In the course of her career as a research scholar, professor, mentor and activist, Williams worked with many different academic institutions, including the Joint Center for Political Studies, Harvard's Kennedy School of Government, and the Institute for Policy Research and Education through the
Congressional Black Caucus Foundation. She started in 1991 as associate professor of government of politics at the University of Maryland, and in 2004 she became a full professor. ==Contributions to political science==
