I am a Research Assistant Professor at the University of Southern California (USC) and a Research Scientist at the USC Information Sciences Institute (ISI) in the research group led by Emilio Ferrara. My research leverages machine learning, data science, and network science to detect, investigate, and mitigate online harms in socio-technical systems. I study malicious behaviors, misinformation, and manipulation dynamics on social media to design algorithms for their detection and identify actionable insights for their mitigation. My study and interest fall into research areas such as computational social science, AI for social good, and behavioral science
