CTO & Co-Founder
Jonathan Silva, PhD
Jon created the SentiAR visualization platform and has oversight for the overall technical design and development to meet current and future clinical applications. It was his original work that secured over $500,000 in grants to build the initial prototype on the Microsoft Hololens platform for in-human engineering trials. As an Asst. Professor of Biomedical Engineering at Washington University in St. Louis, his research laboratory specializes in applying computational approaches to address problems in cardiac electrophysiology. Jonathan is part of the Cardiac Bioelectricity and Arrhythmia Center, and his academic preparation includes a BS from Johns Hopkins University, an MS from Case Western Reserve University, and a PhD in Biomedical Engineering, Washington University.
VP of Technology & Co-Founder
Michael Southworth
Michael is responsible for the company’s holographic platform validation, software planning, and team execution. Prior to joining the project, he developed 3D computer vision exploitation of sensor data for use in airborne platforms as an electrophysics scientist at Boeing Research and Technology. From 2007-2015 at the Johns Hopkins University Applied Physics Laboratory (JHUAPL), Michael specialized in the rapid development of embedded systems for direct deployment to the Department of Defense end users, primarily focused on the technical integration of wireless embedded systems with emerging microelectromechanical systems (MEMS) sensor technology, navigation, electro-optical sensor development and 3D sensor exploitation. Michael earned his BS from UC Berkeley and a dual MS from Johns Hopkins University.
VP of Quality & Regulatory Affairs
Alex Schreiner
Alex is responsible for the company’s regulatory, quality system, and project planning activities. Prior to joining SentiAR, he acted in senior leadership and individual contributor positions in start-up and established medical device companies, supporting product development and commercialization of implantable and surgical devices, electronic and software-containing devices, and external accessories for use by patients and physicians. Alex specializes in creative and efficient regulatory and quality system solutions to ensure safe, effective, and compliant products and processes and predictable regulatory body interactions. Alex earned his BS in neuroscience from the University of Minnesota.
Director of R&D
Sharif Razzaque, PhD
Dr. Razzaque is Director of R&D. He has been pursuing useful and effective applications of AR/VR for >25 years, including apps for the tele-collaborative design and operation of satellites for Lockheed Martin and the US Air Force and measuring physiological signals and cybersickness in VR to help understand how they are affected by technical parameters such as latency, avatar design and simulated motion. He spent 15 years bringing medical ultrasound XR technology from initial concept at University of North Carolina to commercialization and daily clinical use in treating liver cancer and uterine fibroids. Dr. Razzaque has worked as a Senior Software Engineer at Microsoft Mixed Reality and Chief Engineer of Interventional Imaging at Medtronic. He is inventor on over 20 patent applications in Medical XR, which have been licensed to Medtronic and Hologic, and primary investigator on $2.5 million in NIH research grants.Dr. Razzaque earned a MS and PhD in Computer Science from University of North Carolina at Chapel Hill, where he invented the XR interaction technique, Redirected Walking, which has been featured in Wired Magazine and is still an active topic of follow-on research 20 years later.
