Dr Sivakumar’s research interests are in the intersection of health communication and digital media, civic discourse on-line, children’s interpretations of educational media.
Her health communication work revolves around examining how people learn from mediated information especially on topics that have they no prior information or knowledge. Her recent work examines how chronically ill patients evaluate online health websites and how the quality of the information presented in such websites affect patient beliefs about the disease, their compliance intentions, and the trust they have in their doctors. Her work also examines how people make judgments about about the credibility of information they read online and how such judgments can impact their medical decision making. She is especially interested in mapping out how high degree of exposure to online health information affects beliefs about efficacy of alternative medicines.
She is also interested in examining how people who take part in online forums react to cross cutting political information and the effects of exposure to disagreement in terms of civility and politeness. This project involves examining through both content and social network analysis how posters in an online sports forum talk to each other about politics. She is currently working on a project that looks at how comments in the youtube pages can have an impact on affective polarization. She is also involved in another project that examines the themes of the 2016 presidential candidates Instagram posts and the cognitive and affective responses of their audience to these themes.
Dr Sivakumar was also involved in a three part study that examined young children's interpretation of educational media content.
