Grace graduated from the Johns Hopkins University with a Master’s degree in Material Science and Engineering in 2014. In her graduate study, she developed a low-voltage organic phototransistor with an organic small molecule. After her graduation she moved from the east coast to west coast because she loves the all year long sunshine in South California.

She spent 3 years in a start-up company as Device Scientist doing single walled carbon nanotube separation and making thin film transistor with them. Most of her experience with Flash system are gained from there. In 2017, she joined Phenomenex as a Technical Specialist supporting globally, especially the Asia-Pacific area. Bilingual in Chinese and English makes it easy for her to communicate with customers in both US and China.

At Phenomenex she has more opportunity to have hands-on experience in HPLC, GC and SPE. Discussing the crazy troubleshooting cases with other technical members improves her chromatographic skills every day!
