I am pursuing a Ph.D. in Computer Science at Iowa State University, with an anticipated completion date of December 2025 or May 2026. This program builds upon my concurrent pursuit of Master’s degrees in Computer Science and Entrepreneurship, which I expect to complete this Fall 2024. I completed my M.Eng. in Information and Communication Engineering in 2020 from Nanjing University of Posts and Telecommunications, China, where I was fortunate to work with Dr. Xu Minghai. 2017, I received my B.S. in Electrical and Electronic Engineering at the Atish Dipankar University of Science and Technology, Bangladesh.

I am currently conducting Ph.D. research under Dr. Cai, focusing on Conducting an ongoing research project on enhancing privacy-preserving data sharing and analytics on cloud servers in alignment with OSTP's (The Office of Science and Technology Policy Advance Privacy-Preserving Data Sharing Initiative). I have completed my Master’s thesis with Dr. Zhang Wensheng, focusing on Oblivious RAM construction for securing data access patterns in cloud storage systems.
