Olivier Belli, MSc, D.Ing., is a PhD student in Prof Randall Platt’s group at ETH Zurich. He graduated with a master’s degree in high-throughput approaches for biology and an engineering degree in biotechnology from the University of Strasbourg, France, in 2017. Before joining ETH Zurich, he worked for companies developing cutting-edge technologies based on the CRISPR/Cas9 system such Caribou Biosciences (Berkeley, USA) and Horizon Discovery (Vienna, Austria). These previous professional experiences have allowed him to develop strong expertise in mammalian cell culture, recombinant virus production, molecular cloning, next generation sequencing, flow cytometry and gene editing. At the Laboratory for Biological Engineering at ETH Zurich, he develops in vitro methods for high-throughput screening of genetic mutations in human cells.
