PhD Biomedical Engineering
MSc Machine Design
Dr Ehrmann is one of the co-founders of nthalmic technologies, a start up company based in Sydney that conducts research and product development in the field of vision correction. As the Director of Technology at nthamic, he is responsible for all technical aspects of R&D, including instrumentation, metrology and implementation of novel optical designs. He also holds a visiting appointment at the University of New South Wales through the School of Optometry and Vision Science. His professional qualifications include a BEng awarded from the Aalen University of Applied Sciences, Germany (1986); an MSc in Machine Design from the Cranfield University, UK (1988) and a PhD in Biomedical Engineering from the University of New South Wales (1997).
He has held engineering R&D positions in the USA, Israel, Germany, Australia and the UK. Prior to joining the University of New South Wales for his Doctoral degree, he worked for several years for the National Physical Measurement Laboratory in Germany. In his most recent position at the Brien Holden Vision Institute, Sydney, Australia, Dr Ehrmann had been responsible for instrument development and metrology for more than 20 years. He has received numerous awards for his innovative ideas, has published over 50 peer-reviewed articles, and holds a number of contact lens and instrumentation related patents. His interests concentrate on developing innovative methods and products for vision correction devices, including contact lenses and spectacles, as well as vision related measurements. Dr Ehrmann regularly presents at international conferences and has been invited to speak on topics of translational research, myopia and optical metrology. Through is extensive network within the ophthalmic industry, he remains committed to commercialise novel vision correction devices for the benefit of those in need.
