"There is no one who goes out of his house to seek knowledge, but the angels lower their wings in approval of his action."

- The Prophet ﷺ

Welcome to My Webpage!

I'm a PhD student in the College of Information Sciences and Technology (IST) at Pennsylvania State University, currently working in the Penn State Cyber Security Lab under Professor Peng Liu, Raymond G. Tronzo, M.D., Professor of Cybersecurity. Before this, I obtained my bachelor's degree from the Department of Computer Science and Engineering (CSE) at Bangladesh University of Engineering and Technology (BUET) in 2023. After graduation, I served as a full-time Lecturer at United International University (UIU), Bangladesh.

Research Interest:

My research focuses on "AI-Driven Security for Intelligent Systems", securing critical cyber-physical infrastructure, software generation, and networked IoT environments with an emphasis on detecting, reasoning about, and mitigating malicious behavior in complex systems.

Cyber-Physical System Security --- Developed methods to distinguish faults and cyberattacks in DER systems using taint-styled dependency graphs with node pruning and pattern matching. Currently exploring the potential integration of LLMs to enhance Bayesian Network (BN)-based reasoning, improve scalability, and automate knowledge extraction.
LLM for Code --- Investigating vulnerabilities in the LLM code generation process and their potential for producing or developing malicious software, with a focus on detection and mitigation strategies.
IoT Network Security --- Explored security and privacy in Industrial and Smart Home IoT networks, including detecting smart home device activities from encrypted traffic, analyzing ML-based NIDSs on ambiguous IoT traffic, and uncovering false-positive rate manipulation attacks in industrial IoT systems.

Personal Interests

Outside of research, I enjoy playing Chess and am currently in the learning phase, exploring strategies and improving my game.

I also play Cricket and have previously competed as a top-order batsman in school and collegiate tournaments.
