A serial entrepreneur, Dr. Hymel founded the predecessor (Biodyne, Inc.) to Signal Advance, Inc. in 1992 and has served as a Director and its President and Treasurer since its inception. He previously founded a computer systems/network consulting and technology development firm, and later, a medical-legal animation firm which developed over 60 animations used in litigation. He has served on the board of directors of a non-profit corporation, Educational Enrichment Center through 2009. 

His professional experience includes research engineering at the University of Texas, Neurophysiology Research Center where he developed proprietary neurostimulation, signal generation and data acquisition systems,  and control systems engineering for Shell Oil & Development Companies and Johnson Controls, Inc. Dr. Hymel holds a doctorate in biomedical sciences from the University of Texas Health Science Center, Houston, Graduate School of Biomedical Sciences as well as Bachelor’s and Master’s degrees in electrical engineering from Texas A&M University. 

Dr. Hymel has been granted multiple patents, nationally and internationally, and authored a number of scientific/technical publications. Dr. Hymel developed the proprietary Signal Advance technology and successfully demonstrated temporally-advanced detection of a range of analog (including bioelectric) signals in his doctorate research studies. Under his leadership, Signal Advance, Inc. was awarded first place in the 2011 Goradia Innovation Prize competition. Dr. Hymel was recognized as the 2012 Innovator of the Year by the Intellectual Property Section of the Oklahoma Bar Association and named the 2015 Inventor of the Year by the State Bar of Texas Intellectual Property Section.

He has also worked in the areas of product design and manufacturing engineering, quality, regulatory and technical support for startup companies. Mr. Stubbers has managed corporate ISO/EN/QSR quality management systems requirements and compliance and European CE and FDA 510K Class II as well as other regulatory approvals for world-wide medical device distribution.

Mr. Stubbers received his bachelor’s degree in electrical engineering from the University of Idaho in 1985, completed graduate coursework at the University of Texas, Graduate School of Biomedical Sciences and at Rice University, and completed his MBA at the University of Houston (2013).

Naser Otman, BS/MS (Elec Engineering), PhD (Elec Engineering)

HDr. Otman has experience in electrical and optical communications system design, simulation and implementation, and electromagnetic wave interactions with matter. He is highly skilled in analog and digital electronic circuit design, and programming of embedded systems.

Dr. Otman has experience in Laser electronics and optoelectronic circuits design, such as optical transceivers, semiconductor laser diodes driving circuits, and switching circuits of solid-state lasers. He designed and implemented digital wireless optical communications systems with specific optical channel codes using programmable embedded systems.

His professional experience includes research and university instructor. He has worked in developing digital signal processing algorithms for digital image segmentation, enhancement and recognition. He has wide experience in computer simulation for electronic circuits, electronic communication systems, and optical nanostructures. He is skilled in MATLAB programming, RSoft and Optiwave for optical nanostructure design, and PSpice for electronic circuits simulations.

He holds a doctorate in electrical engineering from Dalhousie university in Canada, a Master’s degree in electrical engineering from University of Belgrade in Serbia, and bachelor’s degree from University of Tripoli in Libya. He authored and published a number of scientific papers in peer reviewed journals. Recently conducted research on optical semiconductor nanostructure design and simulation for nonlinear optics application, especially in nonlinear optical frequency conversion and parametric optical amplification.

Michael Watson, Engineering Technologist

Mr. Watson founded Rapid Technologies Intl (RTI) which has been in operation for over 15 years. Based out of Houston, Texas, Mr. Watson and RTI have been providing industrial and commercial entities with solutions both domestically and internationally and has worked in 39 countries, handling projects up to 27M USD. He has 30+ years of experience in providing field services to industry. 

He is a specialist in measurement and control techniques with 20 years of experience in the oil and gas sector. He has also provided services and solutions for municipal entities as well as the private sector with years of experience in “field hardening” of electronics and systems. Mr. Watson has been involved in multiple OEM relationships to develop application specific equipment and/or integrated solutions, has taught safety and industrial training courses in multiple countries and in multiple languages. 

His primary focus has been in the Energy market and his experience includes working with small to large clients/entities to provide multiple solutions for measurement and communications systems, various networked systems including networked radio and hybrid communication systems, industrial and commercial computer networks and IoT systems, as well as encrypted systems for governmental entities. His expertise includes both hardware and software systems for monitoring, alarms, controlled access, etc., as well as SCADA, DCS, and PLC systems. His “real world” hands-on experience makes him a valuable member of this organization in particular with regard to field hardening devices and system.

Danny Lee, BS (Comp Science & Mathematics)

Mr. Lee has 30+ years’ experience in software development for industry including many data protocols for communications equipment utilized throughout multiple industrial systems. He architected initial development and managed development/sales of the popular PGAS system used by many large gas pipelines from 1990 to the early 2000s. He founded a company in 2003 which provided specialized natural gas storage systems software solutions for over a decade before transitioning into technical consulting and real estate investing.

He has worked extensively with Microsoft SQL Server and related development languages to build large terabyte+ database solutions.

Mr. Lee received a dual bachelor’s degree in Computer Science and Mathematics from the University of Texas at Tyler in 1983.
