Welcome to my page! I am a PhD student in the ECSE Department at Rensselaer Polytechnic Institute. I am fortunate to be advised by Tong Zhang. I previously completed a Bachelor of Engineering with Honors in Southern University of Science and Technology, where I conducted research under Quan Chen.

My research focuses on optimizing memory architectures, primarily DRAM and SSDs, to enhance hardware performance and software efficiency. I explore solutions in data processing and AI, aiming to contribute to more efficient and sustainable computing systems.
