Frederic Truffer received his electrical engineering degree in 2004 from the University of Applied Sciences, Sion, Switzerland. His diploma work, entitled “line focus Fourier domain optical coherence tomography”, addressed the imaging of a porcine eye in vitro. This work was carried out in the optics group at Tsukuba University, Japan under the supervision of Prof. Yoshiaki Yasuno.

From 2004 to 2007, he worked as a research assistant at the Institut de Recherche en Ophtalmologie, Sion, Switzerland. His work focused on laser Doppler flowmetry/velocimetry devices to measure blood flow in retinal and choroidial tissue in human eyes. He also worked using Blue Field Simulation, did light scattering measurements in tissue/cells and cell culturing.

In 2009 he received his Master in Optical System Technique at the Hochschule Ravensburg-Weingarten, Germany. The Master thesis was supervised by Prof. Steven L. Jacques from the biomedical engineering department at Oregon Health & Science University, USA. During this, he determined optical properties with confocal microscopy in reflectance and transmission mode and was also involved in measurements of blood content and oxygen saturation during esophagus cancer surgeries.

At the end of 2009, Frederic joined the optoelectronics group at HES-SO (University of Applied Sciences Western Switzerland) where he worked on the development of a small, portable bioreactor to measure water quality based on fluorescents and bioluminescents. He developed a compact laser Doppler flowmeter for small animals and was involved in a project with an absolute laser Doppler velocimeter that was combined with a fundus camera. His current work involves the integration of different physical- and biosensors for the Envirobot project (Nano-Tera, Switzerland). In addition to his research activities, Frederic is also responsible for practical courses in physics for bachelor students and supervises semester and bachelor works.
