About
My research examines the structure, behavior, and language of coordinated actors in online environments. I study how state-sponsored and other malicious campaigns disseminate misleading or harmful content, how duplicate narratives spread at scale, and how computational methods can help identify such behavior.
In addition to research, I have experience teaching and mentoring students in computer science. Prior to joining FIU, I served as a Lecturer in Computer Science at Stamford University Bangladesh, where I taught courses including machine learning, artificial intelligence, operating systems, software engineering, and computer networks.
This website provides an overview of my publications, ongoing research, academic background, and selected projects.

Short Bio
Ph.D. Candidate at FIU with research spanning cybersecurity, social computing, and machine learning, with publications in venues including WWW, USENIX Security, ACM Hypertext, ASONAM, PETRA, and USEC.
Selected Publications
A curated list of selected publications. This section can later be expanded into full conference, journal, workshop, and preprint categories.
Research
Influence Operations and Duplicate Content
I investigate how coordinated actors use repeated or near-duplicate content to amplify narratives and manipulate attention across social media platforms. This line of work includes campaign discovery, account attribution, and large-scale behavioral analysis.
Harmful Language in Information Operations
My research studies toxic language, hate speech, sentiment, and emotion in influence operations, with emphasis on how malicious actors frame messages to attract engagement, intensify polarization, or target specific groups.
Platform Safety and Abuse Defenses
I also contribute to work on abuse investigations and practical defenses for online platforms, particularly approaches that center the experiences and needs of users affected by harmful online behavior.
Methods
- Natural language processing
- Machine learning
- Large-scale social media analysis
- Computational social science
- Reproducible data pipelines
Ongoing Direction
My current work seeks to better understand coordinated influence behavior through textual duplication, narrative spread, and harmful content analysis, while developing more robust and scalable detection methods.
