David Mascareñas has a background in the research and development of novel sensor nodes for monitoring structural health. During his doctoral work, David developed arguably the first application of rotorcraft for the structural-health monitoring/inspection problem. David is currently working on the development of low-power and imager-based distributed-sensor network technologies for monitoring structural health. As part of this work, David has become acutely aware of the security and privacy challenges surrounding use of video in smart cities. He is a strong advocate for smart-city technologies and protocols that respect individual privacy while simultaneously delivering important societal benefits.
