I've recently begun working as an AI Research Engineer at the Digital Safety Research Institute (DSRI), UL Research Institutes. My primary focus centers on the safety evaluation of cutting-edge AI systems that assist in code generation.

I completed my Ph.D. (with MS) in Computer Science from the University of Houston in May 2023. My research advisor was Dr. Alipour and I was a member of the Software Engineering Research Group (SERG). In my dissertation, I explored methodologies to evaluate and enhance the transparency and safety of source code models. During my postdoc, we examined the impact of malicious attacks on code LLMs and investigated approaches to identify and mitigate vulnerabilities through unlearning.

I obtained my B.Sc. in Computer Science and Engineering (CSE) from Khulna University of Engineering & Technology (KUET) in May 2015. Later, I joined BJIT Group, Bangladesh (Aug 2015 - Jun 2018) as a Software Engineer.
