Professor Daniel Hewak

Prof Daniel W Hewak, FInstP, is Professor of Optoelectronics at the University of Southampton, specialising in the production and application of chalcogenides. He has worked with novel materials since 1982 and is recognized internationally as a leader in the production and use of chalcogenides and a pioneer in their fabrication and application.

His research has led to IR fibres for sensing, medical and aerospace, fibre amplifiers for telecom, the first chalcogenide-glass lasers and also solar-cell, thermoelectric and memory devices. This diversity is a testament to the truly advanced functionality of chalcogenides.

Dan is invited to speak at several major international conferences each year, most recently at SPIE Security & Defence Conference (Dresden, Sept 2013), Photonics Global Conference (Singapore 2012), International Symposium on Non-Oxide and New Optical Glasses (St Malo, France 2012). Over the past five years, Dan has contributed to the management of several large projects, notably the EPSRC Centre for Innovative Manufacturing in Photonics (CIMP), which provides strong background for this current proposal.

His research is well funded by industry, including Merck, Pirelli and DSTL and currently via Samsung’s Global Research Outreach Program, and he works closely with Ilika Technologies Ltd on material development and characterization.

He has authored over 270 papers and conference publications (h-index 34), holds 9 patents, with 3 licensed to industry. As Co-I and PI, he has received research funds totalling £11.8M since 2008.
