I am an Assistant Professor of Computer Science in the Department of Mathematics, Computer and Information Science at the State University of New York at Old Westbury. I earned my PhD from the Department of Computer Science at Stony Brook University. Before moving to the United States for higher studies, I studied Computer Science and Engineering at Bangladesh University of Engineering and Technology (BUET).
During my PhD, I was involved in several projects funded by National Science Foundation (NSF), Defense Advanced Research Projects Agency (DARPA), and R&D grant from Northrop Grumman to develop Anomaly Mining algorithms and apply them to solve real-world problems. Recently, we have been awarded an NSF: Computer and Information Science and Engineering - Minority Serving Institution (CISE-MSI) grant (Co-PI) to increase the research capacity at SUNY OW by creating the infrastructure for big data research, incorporating course embedded undergraduate research experience, and training undergraduate students in big data research through seminars, workshops, and summer bridge programs. Moreover, I am working on several projects on misinformation, stigma, and hate speech detection from social media platforms in collaboration with the Third Space research group of the University of Toronto.
I worked as a Research Intern in the Information Security team at IBM Thomas J. Watson Research Center in Summer 2015. After I defended my PhD, I worked as a Research Assistant Professor (non-tenure track) in the Department of Computer Science at Stony Brook University (SBU) for two semesters (Fall 2017 – Spring 2018).
