Rafael Gómez-Sjöberg obtained a Ph.D. in electrical and computer engineering at Purdue University, where he developed a microfabricated sensor of bacterial metabolism for rapid detection of bacterial contamination in liquid samples. After carrying out postdoctoral work at Caltech and Stanford, where he worked on automating cell culture experiments with microfluidics, he led a microfluidics-focused lab at Lawrence Berkeley National Laboratory. From there he moved to Quanticel Pharmaceuticals (a startup later acquired by Celgene Corp.), where he designed and built instruments for isolating single cells from very small cell samples and managed a single-cell analysis and sequencing platform. At CZ Biohub SF, Gómez-Sjöberg leads the Bioengineering platform; he and his team are developing novel scientific instrumentation to support the work of Biohub research groups and research projects. A key goal is to proceed swiftly from concept or prototype to robust instruments that span a wide range of complexity, from low cost devices that simplify manual lab work, and portable instruments for low-resource settings, to robotic systems that enable high-throughput experimentation.
