Research Assistant | VAI Lab

I am now a research assistant at Visual Analytics and Imaging Lab, Stony Brook University under the supervision of Prof. Klaus Mueller. My research interests include medical imaging, machine learning, visualization, big data, robotics, and high-performance computing on GPUs. Currently, I am working on three exciting projects:

  • GPU acceleration of statistical iterative CT reconstruction algorithm.
  • Metal artifact reduction in CT data with known metal components.
  • Communication framework of two 6-axis robot arms synchronized by motion capture system.

As a person I am trying to be humble by accepting my limitations, listening others' words, and rediscovering a sense of wonder.
