Romain PERETTI received his PhD in Physics 2008 at university de Lyon (France) awarding his research on rare earth spectroscopy on optical fiber in collaboration with Alcatel and Draka company He, then joined INL CNRS lab where his research interest focused on photonic crystal (PhC) for applications such as single photon sources, lasers and photovoltaic cells. In 2014 he joined the quantum opto-electronics group of Prof. J. Faist at ETHZ in Zuerich (Switzerland). Here he worked on quantum cascade lasers (QCL) and especially demonstrated the first room temperature PhC QCL.

Since 2016 he is leading the bio photonics terahertz activity in the TeraHertz photonics group at IEMN (Lille, France).

He coauthored more than 30 publications in peer review journal, he is recognized reviewer for OSA since 2014 and part of the scientific committee of the photoptics conference.
