Jan G. Korvink holds a Chair for Microsystems Engineering at the University of Freiburg, Germany, where he also directs the Freiburg Institute for Advanced Studies - FRIAS. He has co-authored more than 160 papers in scientific journals, as well as numerous conference papers, book chapters and a book on semiconductors for engineers. His research interests cover the modeling, simulation and low cost fabrication of MEMS/NEMS, and applications in magnetic resonance. In 2011 he received a European Research Council (ERC) Advanced Grant, the Red Dot Design Concept Award and the University of Freiburg Teaching Award.

Patrick J. Smith is a Lecturer in Manufacturing Technology for the University of Sheffield, UK. He has published over 40 journal and conference papers, and has 3 patents. His main research interests are concerned with reactive inkjet printing, controlled crystallisation using inkjet and additive manufacture.

Dong-Youn Shin is Assistant Professor at the Pukyong National University in Busan, South Korea. Before his appointment, he was research engineer at LG Chem Research Park and then senior research scientist in the division of nanomechanical systems at the Korean Institute of Machinery and Materials in South Korea. He holds 38 patents and over 70 conference and journal papers. His research interests lie in maskless lithography and fine pattern generation for displays and electronics with the piezo inkjet printing technology.
