Post Doctoral Researchers

Dr Guohua Hu is a Post Doctoral Researcher in the group. His PhD thesis was on Printable 2D Material Optoelectronics and Photonics. Guohua made several key achievements in the field of functional printing during his doctoral work. He was the lead inventor of the patent on formulation of 2D material dispersion in non toxic solvents, culminated in the development of a highly conducting graphene ink that could be printed like a “newspaper”. This was highlighted in the University research news.
This also lead to the formation of HNE's first spin-off Inkling Cambridge Limited. One of Guohua's recent works in Nature Communications presented key technological advancements in functional ink formulations with 2d material nanoflakes. This article also received a huge media and industry attention, including from Optics.org, Phys.org, TheEngineer, China Daily.Guohua also has a Bachelors in Engineering degree in Electronic Science and Technology from the University of Electronic Science and Technology of China (2013).
