Prior to joining Oregon State in 2014, Dr. Johnston was founder of Bialanx, developing a portable platform for label-free sensing applications; this effort was awarded an NSF SBIR grant in 2013 to support biosensor development for radiation biodosimetry. He was previously a graduate student and postdoc with the Bioelectronic Systems Lab at Columbia University, where his research focused on monolithic integration of piezoelectric materials and devices with CMOS integrated circuit substrates. In 2012, Dr. Johnston worked as an associate for a New York City venture capital firm investing in early-stage life sciences companies, with a focus on technology assessment for medical devices.

Dr. Johnston was co-founder and Manager of Research at Helixis, a Caltech-based spinout developing instrumentation for real-time PCR, from 2007 until its acquisition by Illumina in 2010. He is also a co-founder of Chimera Instruments, which designs high-speed electrophysiology amplifiers for biophysics research applicatons. He has previously held positions with with Cavium Networks and the Aerospace Corporation. His current research interests include CMOS-integrated bioelectronic platforms, point-of-care chemical and biological sensors, and low-power distributed sensing applications.
