we are sentinel occupational safety

We are a passionate team of professionals working to usher in the future of safe and productive work. Born out of America’s Small Business Innovative Research Program and Aptima Ventures, Sentinel Occupational Safety is a leader in the use of industrial IoT for occupational health and safety optimization. Humans have been and always will be more important than hardware. We don’t just believe in this philosophy, we’ve developed an entire system around this premise. Come join us in our quest to personalize safety and provide a safer work environment for all.

Zach Kiehl is the CEO and President of Sentinel Occupational Safety. His passion lies in the use of innovative technology to remedy and optimize human health and safety in all aspects of life. His background in biomedical engineering and past experience developing innovative solutions for the DoD allow him to lead Sentinel’s vision of using technology to provide a safer work environment for all. Prior to his role at Sentinel, Zach was the Human System Performance Capability Lead at Aptima, a role that allowed him to work on some of the most challenging human-centered problems faced by the DoD. Zach holds a an M.S. and B.S. in Biomedical Engineering from Wright State University. He also holds an MBA from Indiana University’s Kelley School of Business. Mr. Kiehl has numerous professional publications and three pending patents in the realm of human health and safety sensing.

Kevin Durkee is the research and development lead for the SafeGuard Monitoring System. With a background in human factors and applied cognitive psychology, he has worked on a variety of innovation projects for more than 15 years focused on developing new tools that make our world a safer and healthier place to work. Kevin’s career has tackled many challenging research problems in aviation, defense, and industrial work environments through the introduction of new emerging technologies and user-centric design. He has served as Principal Investigator on many projects for the U.S. Air Force, U.S. Navy, Defense Logistics Agency, and NASA. Kevin has an M.A. degree in Human Factors and Applied Cognition from George Mason University, and a B.A. degree in Psychology from DePaul University.

Matthew Ewer holds an MS in Computational Mathematics from Stanford’s ICME, and a BS majoring in Computer Science and in Mathematics from Cornell College.  In addition to reading, art, music, foreign languages, and a procession of miscellaneous hobbies, he has been programming for nearly 20 years, and enjoys working on simulators, 3D printing, and (now that he has a salary to support the habit) microcontrollers.

John Feeney is a founder and Principal Engineer at Sentinel Occupational Safety. He brings his diverse educational background and professional experiences to design and develop systems allowing users to work safer and more efficiently.  John’s ease in working with our customers lets Sentinel deliver custom solutions to meet their specific needs. His professional experience covers the complete lifecycle of system develop from inception through maintenance performing in diverse roles such as designer, developer, analyst, QA, on-site support, and as program manager. John attempted a career as a professional student earning undergraduate degrees in computer science, a master’s in software engineering, and doctorate in applied experimental psychology focused on designing systems that are easier to learn and use efficiently.

Noah DePriest is the chief software architect for the SafeGuard Monitoring System. He has a desire to engineer software systems that have a tangible, positive impact on the lives of everyday people. Throughout his 10+ years of professional experience, Noah has led the software design and development of many projects for the DoD. His main area of focus has involved creating software for human-system environments that aim to improve the overall efficiency and safety of those environments. He has also worked closely with scientists to integrate advanced analytics and algorithms into software architectures to provide near real-time assessments. Noah has experience developing back-end systems which utilize cloud-based infrastructure and services, as well as developing front-end user interfaces using web-based technologies. Mr. DePriest received his B.S. in Computer Engineering from Ohio Northern University.
