Executive team - Signal Advance, Inc.
Chris Hymel, Ph.D., Engineer/Scientist, Director/CEO/CFO
Dr. Hymel is the founder, President, and Principal Investigator of Signal Advance, Inc., and a nationally recognized innovator in analog signal processing and neuro-engineering. He holds B.S. and M.E. degrees in Electrical Engineering from Texas A&M University and a Ph.D. in Biomedical Sciences from the University of Texas Health Science Center, where his doctoral research first demonstrated real-time, temporally advanced detection of bioelectric signals, the theoretical foundation later published in IEEE Circuits and Systems Magazine. He is the sole inventor of U.S. Patent No. 8,452,544 and co-inventor of U.S. Patent No. 12,126,720, which underpins the Analog Guard® encryption platform, and holds additional patents covering analog signal transformation, secure signal processing, and analog-digital synchronization. His innovation has earned the Goradia Innovation Prize, Texas Inventor of the Year, and Oklahoma Innovator of the Year.
Dr. Hymel took Signal Advance from startup to public listing (OTC: SIGL) and leads the company’s technical direction, patent strategy, and commercial vision, guiding Analog Guard toward FIPS, ITAR, and DoDIN-certifiable, AI- and quantum-resilient cybersecurity for fintech, defense, and critical infrastructure.
