Dr. Hongjun Zeng is a leading expert in Optical MEMS, microfluidics, micro and nano fabrication. Dr. Zeng received a PhD degree from Chinese Academy Sciences. He has 15-years of extensive experience in the development of the MEMS/Nano devices and fabrication techniques, including Moving Mask lithography, agile actuators – especially micro-mirrors, micro-screening chips for toxin detection, nanochannels and materials for nanofabrication. Currently, he is in charge of developing novel thin-film diamond products for different industrial applications. Before joining ADT, Dr. Zeng was a research and development engineer at Foxconn and a research scientist at the University of Illinois at Chicago. Dr. Zeng was an inventor and core investigator of several novel microfabrication techniques. He was a co-principal investigator in the Chinese Academy of Sciences Knowledge Innovation Program (KIP), which specifically supports “technologies with strategic significance”. He was a winner of second class Deng Physics Prize in 1996 and the third class Prize of Sichuan Province Science and Technology Improvement in China 2001. He authored/co-authored 6 patents/disclosures and more than 60 publications and presentations. Dr. Zeng was elected as a senior member of IEEE and full member of Sigma Xi in 2006. He is a senior reviewer of many top journals, such as Optics Letters, Optics Express, Nanotechnology, IEEE-PTL, JMEMS, JMM, JVST-B, etc.
