Eric Logean received his diploma in Electrical Engineering from the Technical Institute of Sion, Switzerland, in 1993 (HES-SO). From 1995 to 2004, he was an engineer with the Optics and Biophysics Laboratory at the Institute of Research in Ophthalmology in Sion, Switzerland, developing laser Doppler instruments for retinal blood flow measurements. In 1997, he was visiting the Applied Optics Group at the University of Tsukuba, Japan, where he designed and fabricated synthetic holograms. In 2004, he became a graduate research assistant with the Applied Optics Group at the National University of Ireland in Galway from where he received his PhD degree in Physics in 2009 for his work on retinal imaging using adaptive optics. Since then, he is a scientist at the Ecole Polytechnique Fédérale de Lausanne working in micro-optics design.
