Our Company

EMTensor is the leader in developing electromagnetic tomography (microwave) imaging devices—the safest and smallest of all tomographic modalities.

EMTensor is owned by its founders and backed by venture capitalists. To date, $20 million of private and public funds have been invested. Governmental agencies from the USA (National Institutes of Health), Switzerland, and Austria have financially supported development of this technology for many years.

EMTensor is based in Vienna, Austria, and Fremont, California, USA. Its growing number of experienced engineers and support staff is currently 15.

Our mission is to bring innovative technologies to practical diagnostics of brain pathology, including strokes and brain injuries, followed by 24/7 monitoring of functional viability of tissue and assessment of treatment efficacy or adverse effects.

Our Goals

To create a unique infrastructure based on compact devices, information-processing systems, and services that will be a breakthrough in brain diagnostics. We are shifting the paradigm from a reactive approach, in which treatment follows a delayed diagnosis, to a proactive and preventive approach, in which early diagnosis leads to early, successful treatment.

Every day, we bring forth innovative ideas to save lives.
EMTensor technology can revolutionize healthcare science.

Our Team

We are a multidisciplinary, international team of leading scientists, engineers, and clinicians specializing in the research and development of modern technologies for fast brain imaging and functional monitoring.

Dr. Stephen Pearce
EMTensor CEO

Stephen has designed and implemented patentable systems, with numerous awarded and pending patents to his name, and has over 20 years working on multi-computing based CT/MRI/3D Ultrasound, global satellite monitoring and ground equipment (especially interference mitigation), SIGINT/EW/COMINT/ELINT mobile (land/sea/air) and country level deployed solutions, RFID and Real Time Location Systems (RTLS) and systems engineering consultancy for novel RF system solutions.

Prior to EMTensor, he held leadership technology and business strategy positions at VT iDirect, Kratos Communications, Zebra Technologies, Harris Corporation, Leonardo DRS, Mercury Systems and Elettronica. Typical compound annual growth rates driven at all employers were sustained for 2-5 years and in excess of 100% in 3 years or less. This was achieved at scales from startup through $150M/yr direct revenue responsibility or $250M/yr indirect.

Stephen holds a PhD in Electromagnetics and RF Systems Design, with a Masters in Electromagnetics Propagation and a B Eng in Electronic and Electrical Engineering, all from the University of Birmingham, UK.
