When Wang was in his third year at Stanford, this professor unexpectedly left for MIT, leaving Wang to find a new advisor. This led to difficulties with his research on the use of semiconductors to study nanoscale device structures, and he now estimates that he'll need at least three more years to complete his PhD.
不料第三年指導教授竟跳槽至東岸的麻省理工學院，他只好另尋指導教授，以致「用半導體製程研究微小機械結構」的研究出現了銜接不下去的瓶頸，估計至少還要 3 年才能拿到學位。
