Megan Stubbs-Richardson, Ph.D.
Primary Investigator
Dr. Megan Stubbs-Richardson is an Assistant Research Professor at the Social Science Research Center (SSRC) of Mississippi State University. She directs the Data Science for Social Sciences Laboratory at the SSRC. She is leading one of the laboratory's missions to create open-source social media-based infrastructure projects to broaden participation in social media research. Megan has been a PI or Co-PI on projects funded by the National Science Foundation (NSF), the National Institute of Justice (NIJ), the Bureau of Justice Assistance (BJA), and the Department of Defense (DoD). She has been conducting social media data analyses at the SSRC since 2012. In her research, she uses digital data to identify crime patterns and trends alongside examining digital data’s role in crime prevention. She serves or has served as PI for the COPE-ID Data Viz projects, which initially provided almost 15 million posts about how people coped during the pandemic on 10 social media platforms. The database is now paired with the data visualization and analytics tool, allowing users to draw down data samples more easily and blend social and computational scientific research methods to examine the data.

Stubbs-Richardson often collaborates with SBE scientists and computer scientists to access and integrate data science and social science methods across large volumes of social media data to examine various social problems. For this initiative, she has provided oversight of the two awards (NSF #2031246 and #2318438) while also leading the development of the user guides for the COPE-ID's database and data visualization tool and associated methods, such as the topic modeling user guides. She is also working toward broadening research participation in social media research by sharing presentations with potential users and then evaluating the effectiveness of the COPE-ID data visualization tool.

Sujan Anreddy, Ph.D.
Co-PI
Dr. Sujan Anreddy joined SSRC in January 2018 as a computer specialist, and after completing his PhD, he was named an assistant research professor. He currently works on the Health Resources and Services Administration (HRSA) funded project, “Child Health and Development Project” where he is designing and managing an integrated database that links educational records from MS Department of Education (MDE) with health records from the Division of Medicaid and the Mississippi State Department of Health. As part of managing this integrated database, he deals with technical issues related to system maintenance and data quality, such as integration, consistency and integrity and provides support to data analysts. Additionally, given his expertise in data visualization, he provides the SSRC with the capacity to develop data dashboards and interactive visualizations. He holds a doctorate in Computer Science from Mississippi State University, specializing in data visualization. His expertise and research interests include applying and evaluating machine learning algorithms and building visual patterns using interactive visualization techniques to help analysts explore, identify, and comprehend big data features at multiple levels. https://orcid.org/0000-0003-3362-1332
https://orcid.org/0000-0003-3362-1332Contribution to Project: Co-PI Dr. Anreddy (Visual Analytics Computer Scientist) has years of experience developing visual analytical products for public health and safety needs. His expertise in visual analytics and prior experience mentoring computer science graduate and undergraduate students working with social media data is informative for the objectives outlined in this infrastructure project.
Terri Hernandez, Ph.D.
Co-PI
Dr. Terri N. Hernandez is an Associate Professor of Public Relations in the Department of Communication at Mississippi State University, where she also serves as the Public Relations Concentration Coordinator. Her research explores the intersections of social and digital media, inter/intragroup relations, and consumer behavior, focusing on organization–public relationships, branding, and strategic communication. She has years of experience working with social media datasets, applying quantitative and qualitative methodologies to explore the data. Further, her scholarship spans both theoretical and applied domains, integrating insights from social science with professional practice, such as user experience design in websites and other digital applications. Her collaborative work with the NSF and MSU’s SSRC has expanded her expertise into large-scale data analytics, machine learning, and interdisciplinary research infrastructure. In particular, her recent NSF-funded projects involve building data repositories and developing methods to analyze social media data, addressing challenges like restricted access to platforms like X (Twitter). By creating accessible research tools, she aims to support scholars in examining critical social phenomena, including misinformation spread and public sentiment during crises. Dr. Hernandez’s work has appeared in leading journals such as the Journal of Consumer Marketing, Social Media and Society, and Computers & Human Behavior. She has co-authored multiple peer-reviewed journal articles and book chapters, and her creative scholarship has earned more than 30 professional awards from PR associations, including SPRF and PRAM. https://orcid.org/0000-0003-1939-7266Contribution to Project: Co-PI Dr. Terri Hernandez’s (Communication & UX Design Social Scientist) expertise also aligns with conducting user experience research where she will lead the user experience studies from the beginning stages of the design to the evaluation phase of the project. Hernandez also has experience developing websites (having also developed the current COPE-ID and DS3 websites referenced earlier).

Contribution to Project: His expertise in working with large volumes of social media data and data science applications will also greatly aid us in developing COPE-ID VAT.
Josh Dowdy, M.S.
Consultant
Contribution to Project: Josh has years of experience analyzing and extracting relevant information from large volumes of textual data composed of a variety of sources and languages. He has created, curated, and maintained pivotal databases and procedures to meet the requirements of a variety of tasks including topic modeling, document clustering, and anomaly detection. His expertise gained from working in an industry where customers rely on the results of an advertised product will be very useful as this project aims to provide knowledge and understanding of the COPE-ID dataset with hopes of being extended to support any dataset of its nature in the future. Josh has created all backend functionality and integrated Elasticsearch which allows a user of the platform to search for a variety of terms, topics, and sources across millions of documents within milliseconds. He has also worked closely with Chris and Jacob to establish a normalized data structure for the documents to ensure quality and accuracy.
