Delft, The Netherlands

I am a Ph.D. researcher in Electrical Engineering at Delft University of Technology, advised by Dr. Geethu Joseph. My research focuses on autonomous perception and occupancy grid mapping for autonomous vehicles, with emphasis on sensor fusion (radar-LiDAR) and sparse Bayesian learning.

Previously, I completed my M.Sc. in Electrical Engineering at Delft University of Technology, where I researched distributed Gaussian process learning for multi-agent systems under the supervision of Dr. Raj Thilak Rajan. I also hold a B.Eng. in Information Engineering from Xi’an Jiaotong University.

My research interests include: convex/non-convex optimization, distributed signal processing, multi-agent systems, and deep learning applications to autonomous systems. I am proficient in Python, C/C++, MATLAB, and have experience with FPGA and Linux environments.
