About Me

I am a PhD Candidate in Computer Science at the School of Informatics, Computing, and Engineering Indiana University Bloomington, working as a research assistant in Privacy Lab under supervision of Dr. Apu Kapadia. Before starting my Ph.D., I completed my undergraduate in Computer Science and Engineering in 2012 from Bangladesh University of Engineering and Technology (BUET).


During my graduate study, I did internship at Magic Leap as a privacy engineering intern, a research internship at Microsoft Research India where I explored the privacy issues of sighted bystanders regarding their information sharing preferences with assistive technology, and a research intership at International Computer Science Institute (UC Berkeley affiliated research institute). I also worked as a visiting researcher in the CyLab at Carnegie Mellon University.

Research Interest

My research interests span various topics in usable security and privacy including accessible privacy and security,security and privacy of wearable devices, and social media privacy. As a researcher, I prefer to make impactful contributions to the real world through my research. I want to address various security and privacy issues using Machine Learning, Data Mining, and Computer Vision. My research investigates the ways to improve the privacy and security issues of people with visual impairments using wearable cameras.
