Dr Wen-Kai Hsiao

Research Associate

Inkjet Research

 

Research interest

  • The impact, coalescing, and mixing of inkjet deposited drops on surfaces
  • Integration of product innovation and manufacturing process development

Background

Kai Hsiao studied Mechanical Engineering with a B.S. from University of California, Santa Barbara and both M.S. and Ph.D. from Massachusetts Institute of Technology. After obtaining his doctoral degree in 2004, he worked briefly in MIT Media Lab developing an interactive digital media table (TView) before joining Alvatec, a start-up company in Austria specialising in processing alkali metal alloys for vacuum vapour source and insulation getter applications. He joined Inkjet Research Centre in April 2007 to study the dynamic deposition behaviour of picoliter sized ink drops on surfaces, with aim to help developing a new generation of inkjet-based digital manufacturing processes.

 

Kai has been appointed as Associate Lecturer in Engineering in Newnham College since September 2010.
