Research Interests:

• 4D treatment planning in IMPT
• Robust optimization in IMPT
• Computational physics
• High-performance computing

My primary research interests are in the development and implementation of high-performance computing (such as memory-distributed parallel computing using MPI and/or OpenMP and memory-shared parallel computing using GPU) and its application in treatment planning for radiation therapy, especially in IMPT. The major goal of my research is to investigate issues related to and develop an effective and efficient treatment planning scheme for radiation therapy. The potential applications include robust optimization in IMPT to take into account setup, range, uncertainties and regular/irregular organ motion, improvement of the accuracy and efficiency of the current treatment planning software and dose calculation engines in protons etc.

A tutorial in my group would provide experience in robust optimization in IMPT, 4D treatment planning, and applications of high-performance computing in radiation therapy.
