About

Who they are

Dr. Kellogg’s struggle with a mystery illness led him to pioneer technology for measuring thousands of molecules in self-collected blood microsamples. This allows for a better understanding of health fluctuations and the impacts of health interventions in detail. When combined with wearable sensors and symptom tracking, this technology allows for real-time health monitoring and pattern discovery with unprecedented resolution. PhD in Microfluidics and Systems Biology from ETH Zurich.
