Tobias Funk, PhD
Senior Director, X-Ray & Imaging

Dr. Tobias Funk has years of experience in the development of instrumentation for science and medicine. Prior to joining Triple Ring, he worked as a researcher at Lawrence Berkeley National Laboratory and in the Department of Radiology at the University of California, San Francisco. Tobias is an experimental solid state physicist by training and has focused on utilization of ionizing radiation throughout his career. He developed synchrotron instrumentation for spectroscopy on proteins and ultra-low temperature equipment for nuclear solid state physics. More recently, he worked on SPECT imaging and developed a dedicated cardiac SPECT system that was successfully brought to market. At Triple Ring, Tobias focuses on developing products around the use of ionizing radiation. One example is a simulation package for explosive detection with X-rays for the Department of Homeland Security.

Tobias received his MS and Ph.D. from Freie Universitat Berlin, Germany. He has authored over 20 peer-reviewed publications and has over 10 granted and pending patents. He is a reviewer, an associate editor, and a member of the editorial board for various peer-reviewed journals.
