A portrait of Joe Heanue, a smiling man with glasses against a gray background.

Joe Heanue, PhD

President and CEO

Dr. Joe Heanue has significant leadership experience in device and instrumentation research & development within interdisciplinary environments. He previously served as Vice President of Engineering at NexRay and at Signature Bioscience. At NexRay, Joe led the development of a low-dose x-ray imaging system for interventional cardiology. At Signature, he headed a group that delivered prototype RF and microwave spectroscopy instruments to a major instrument partner; the first of these instruments was launched in 2005 by MDS Sciex.

Joe’s extensive research and development experience includes the analysis and design of complex systems, x-ray and gamma-ray detector development, low-noise analog electronics, data-acquisition systems, signal and image processing, high-speed data-processing architectures, and thin-films failure analysis.

Joe holds patents for detector and image processing, spectroscopy, and a patent for medical system imaging architecture that is licensed to a major medical equipment manufacturer. He received a BS in Physics from the Massachusetts Institute of Technology and earned his Ph.D. in Electrical Engineering and Computer Science from the University of California at Berkeley. Joe was a postdoctoral researcher at Xerox PARC, and he has completed the Stanford University Executive Program for Growing Companies.
