Welcome

I am currently working as a researcher at the cyber security department of Visa Inc, U.S.A. I am doing research on computer and network security that focuses on Intrusion Detection Systems, Intrusion Prevention Systems, Network Monitoring Systems, and Digital Forensics.

I received my Ph.D. in Computer Science in April 2018 from the University of Alabama at Birmingham (UAB). I was supervised by Dr. Ragib Hasan towards my Ph.D. My doctoral committee members were Dr. Anthony Skjellum, Dr. Alan Sprague, Dr. Purushotham Bangalore, and Dr. Allen Jhonston. During my Ph.D., I engaged myself in diversified areas of computer security. Additionally, I served as a Teaching Assistant and Laboratory Instructor at UAB.

I completed my bachelor degree in Computer Science and Engineering from Bangladesh University of Engineering and Technology (BUET) in October 2009. I was supervised by Dr. Mostafa Akbar during my study at BUET.

Before joining UAB as a Ph.D student in Fall 2014, I had been working in software industry for five years. I served Samsung R&D Institute Bangladesh (SRBD) as a Lead Engineer at the Dept. of Solution Lab for the period June 2010 to August 2014. I developed a secure media (audio, video, and image) sharing framework using Windows Runtime platform while I was working at Samsung.
