Brief Biosketch

Prior to joining Poly U ISE, Dr. Wen was an Assistant Professor in the Department of Mechanical Engineering at City University of Hong Kong and a postdoctoral fellow at the Argonne National Laboratory in the United States. Dr. Wen was born and raised in Canton and received his bachelor's and master's degrees in physics (optics) from Sun Yat-Sen University before moving to the United States to earn his Ph.D. in Materials Science from Rice University, a top-20 institution in the United States.

We design and make one-of-a-kind equipment and materials to create useful manufacturing technologies with ultimate intelligence and precision for applications in optics, electronics, and biomedicine, etc.

In addition to publishing prestigious journals, we also pursue industrial success.

We are actively seeking highly-motivated Ph.D. candidates and Postdocs, particularly in the fields of physics, optics, optical engineering, 3D printing, mechanical engineering, robotics and controls, polymer, and ceramics.

Research Interests

• Intelligent Additive Manufacturing
• Nanomanufacturing
• Ultrafast laser manufacturing
• Advanced optical metrology, imaging, and spectroscopy
• Equipment and materials for semiconductor processes
