Professional Experience

2010 – present: Senior Research Engineer

Seagate Technology, Media Research & Development, Fremont CA

• Developed computational software to investigate magnetism at nano-scale and carry out large

scale numerical simulation.

• Built a model to predict the complex-alloy properties based on historical data, using machine

learning algorithm. The model is widely used across Seagate.

• Collaborated intensely with engineers from different divisions in a cross-functional setting, by

providing statistical data analysis, modeling support and experiment guidance.

2006 – 2010: Graduate Research Assistant

University of Minnesota, Physics Department, Minneapolis, MN

• Pioneered in applying quantum transport theory and non-equilibrium Green's function (NEGF)

formalism in the field of spin-based electronics.

• Discovered spin-wave induced oscillatory coupling between spin-torque-oscillators from

numerical simulation and explained the results with an analytical theory.

• Came up with and implemented a fast recursive algorithm to evaluate quantum transport

coefficient, making quantum mechanical simulation of long nanowires possible.

• Invented the concept of exchange-assisted switching in magnetic random access memory and

pushed the technology towards commercialization.

2004 – 2005: Undergraduate Researcher

University of Science and Technology of China, Hefei, China

• Applied quantum mechanics to classical game theory, in particular with incomplete

information.
