In 2008, Marshall became an assistant professor of computer and information technology in data management at Purdue University's College of Technology.[7] She joined the faculty at Spelman College in 2014 as an associate professor of Computer Science in the Division of Natural Sciences and Mathematics and became Chair of the Computer and Information Sciences department in 2016.[6] At Spelman, she is the Director of the Data Analytics and Exploration (da+e) Laboratory, which centers on more effectively characterizing complex networks of data to generate useful knowledge.[6] Her research focuses on business intelligence and data analytics, social media, and cybersecurity.[6]
#BlackTwitter Project
One of Marshall's research projects centers on the use of social media, and Twitter in particular, for advancing social movements across the black community through the use of the hashtag #BlackTwitter.[8] Her team works with Twitter's application programming interface (API) to gather, analyze, and visualize trends in Twitter data to answer questions like who makes up Black Twitter, who are the influencers within the community, and what issues and topics are they responding to as a community. The project also took the form of a course for Spelman College's Interdisciplinary Big Questions Colloquia, exposing students to principles of data science through by collecting, storing, and analyzing social media data related to the #BlackGirlMagic hashtag.[9] Analysis of the efficacy of the course itself was presented at the Institute of Electrical and Electronics Engineers' Frontiers in Education Conference as a way to teach data science concepts in a culturally relevant framework, since the course also wove in themes of black girlhood alongside computational approaches to data analysis.[10]
Business Intelligence
Marshall has also contributed research to business intelligence, working to organize, integrate, represent, and analyze a diverse array of data to enable businesses to glean more knowledge and keep pace with the increasing rate of data generation. She has worked on a broad range of problems—from recommending more refined algorithms for music recommendations to designing cost-effective cybersecurity security measures to harnessing the power of eye tracking to better design products for consumers.[11][12][13]
Broadening participation in data science
In addition to her research interests, Marshall is involved in a number of efforts to increase representation of underrepresented groups in data science and increase data readiness across the workforce.[14] She is the Principal Investigator (PI) of the Data Science eXtension (DSX) program, which is funded by a National Science Foundation grant.[15][16] The program is an effort to train faculty at Spelman College and Morehouse College—both historically black colleges and universities (HBCUs) in Atlanta—on how they can infuse data science and analytics into their curricula. DSX seeks to highlight how data science connects to multiple disciplines, while increasing awareness of opportunities in data science to a student body that is currently underrepresented in the field.[9][17] The project was informed by a 2016 NSF-funded workshop on "Planning a Dual Institution Research Center in Socially Relevant Computing."[18]
Marshall has also lent her expertise to furthering data science training at the undergraduate level, serving on the National Academy of Sciences' 2018 Roundtable on Data Science Postsecondary Education.[21]
