After completing her doctorate, Cotwright-Williams worked as a tenure-track faculty member in mathematics at
Wake Forest University,
Hampton University, and
Norfolk State University. While working there, in an effort to shift her career to a government track, she began studying
public policy and working on collaborative research on
Bayesian network based drone control systems with
NASA, and on a
US Navy project involving
measurement uncertainty. In 2010, she completed a Graduate Certificate in Public Policy Analysis at
Old Dominion University. She applied for an
American Mathematical Society Congressional Fellowship, and was turned down on her first application but succeeded in her second, in 2012. Cotwright-Williams also became a 2012–2013 Legislative Branch Fellow, under the
American Association for the Advancement of Science Science and Technology Policy Fellowship program. She also worked as a science and technology Fellow for both the Senate and the House of Representatives. While a Congressional Fellow she worked as a staffer on the majority staff of the
U.S. Senate Homeland Security and Governmental Affairs Committee and her responsibilities included responding to the
Boston Marathon bombing in 2013. In 2014 she worked on
data quality for
United States Citizenship and Immigration Services, and in 2015 she became Hardy-Apfel IT Fellow at the
Social Security Administration. Her work at the Social Security Administration has included
business analytics to prevent fraud and support
data warehousing. In 2018, with the fellowship expiring, she moved again to the
United States Department of Defense as a data scientist. Cotwright-Williams continues to hold an adjunct professorial lecturer position in mathematics and statistics at
American University. She serves as an at-large member of the executive committee of the
Association for Women in Mathematics (AWM). Her career advice includes the following quote: "Get out and talk to people and learn new things!" == Awards and honors ==
