Hi, I am a 3rd year Ph.D. student in Computer Science at the University of California, Riverside (UCR) under the supervision of Prof. Nael Abu-Ghazaleh. My primary research domain is security and privacy of Machine Learning (ML) and Large language model (LLM). My research works involves analyzing the unused parameters within an overparameterized machine learning model.  My goal is to understand how they can be used by the attacker to store hidden information. Moreover, I am also investigating the privacy attack in large language models (i.e., bypassing guardrails to leak sensitive information through LLM output, Memorization of private data in LLM while training). Additionally, I am also actively exploring the security attack of LLM (i.e., prompt injection, backdoor attacks, adversarial attacks in both unimodal and multimodal LLM)


My goal is to build up an impactful research career, where I can preserve the Privacy and Security of users' data to make a meaningful contribution towards society with my experience. My research works require efficient code writing, sometimes need to find the vulnerabilities on an well-established environment,  or sometimes they require me to design the defense of my own well-established attack. I literally love that! Before jumping to implementation, I always prefer to think critically outside of the box, reason logically, learn and compare the pros and cons. I'm a self-motivated and hardworking person.


Previously I served as a faculty member at Department of Computer Science and Engineering (CSE) of Bangladesh University of Business and Technology (BUBT), Dhaka, Bangladesh. Before that, I worked for Linkstaff  Co., Ltd at Tokyo, Japan as a Foreign Software Engineer. I accomplished my B.Sc. in computer science and engineering on April, 2019 from Bangladesh University of Engineering and Technology (BUET).  Prof. Md. Shohrab Hossain was my supervisor for B.Sc. thesis. My undergraduate research work covers  Blockchain and Human Computer Interaction (HCI) with a number of publications.
