I am a 3rd year PhD student from Taiwan, working at the Laboratory of Turbomachinery and Components in Engineering Mechanics at Virginia Tech.  My research interest is Fluid Dynamics,  Applied Mathematics and Lubrication Theory. My career goal is to become a professor in the university. In my spare time, I like doing crossfit training, crocheting and baking.
