Matthew Johnston combines sensors, circuits, and systems to develop integrated technology platforms for chemical and biological applications. Before joining Oregon State, he was a graduate student and postdoc at Columbia University in the Bioelectronic Systems Lab. Matt was previously a co-founder of Helixis, a Caltech-based startup company developing low-cost, real-time PCR systems that was acquired by Illumina in 2010. He has since worked with a few other small technology companies on electronic instrumentation for the life sciences. Matt’s current research interests include biosensor and bioelectronic platforms, massively-parallel sensing, and lab-on-chip technologies for medical monitoring and point-of-care diagnostics.
