E-mail: Sujan Anreddy
Sujan Anreddy joined SSRC in January 2018 as a computer specialist. After completing his Ph.D., he was named an assistant research professor. He works on products that integrate technology into program evaluation. His work helps tobacco control program grantees manage their activities, which in turn helps evaluators validate the programmatic data for providing short-term, medium, and long-term intervention outcomes.
He holds a doctorate in Computer Science from Mississippi State University, specializing in data visualization. His research agenda focuses on building and evaluating visual analytical tools for public health and safety. Previously, as part of an NSF grant, he worked alongside computer science graduate and undergraduate students in building a comprehensive database to identify misinformation associated with COVID-19 from social media and web-based forums. His research interests include using and evaluating natural language processing techniques for identifying misinformation in social media data. As part of the “Child Health and Development Project” (CHDP), he developed visualization products presenting information on resources available to parents, and health care providers of children ages 0-5 years in Mississippi.

Madeline Burdine joined the SSRC in January 2024 as a research associate. Burdine received her bachelor’s degree in communication from Mississippi State University. She earned a master’s degree in integrated marketing communication (2022) as well as a master’s degree in sociology (2024) from the University of Mississippi. As a graduate student at the University of Mississippi, Burdine put her passion for the social sciences to work in a number of ways. She served for one year as a graduate assistant for the Sarah Isom Center for Women and Gender Studies before being selected to serve as a graduate research assistant on a research project funded by the National Science Foundation (NSF). Over the course of the project, Burdine was part of interviewing over 100 White southerners to explore how they feel about their place within the racial hierarchy today. Burdine’s thesis explored how heterosexuals who are considered supportive of the LGBTQ+ community navigate and maintain relationships with their LGBTQ+ friends and family within the conservative state of Mississippi. Burdine has also conducted interviews for the Queer Mississippi Oral History Project.
As a research associate at the Social Science Research Center, Burdine has worked on projects within the following labs: Mississippi Tobacco Data, the Gender Impacts Lab, and the Evaluation and Research Group. Her diverse skillset allows her work to range from data collection to graphic design expertise in the formulation of reports.
Burdine is currently completing courses toward a Ph.D. in Sociology from Mississippi State University.
