Microphones are everywhere, and they are growing at a rapid speed. Their presence in every mobile phone, as the core sensor, has already made them ubiquitous. However, their renewed proliferation is not due to this traditional usage, rather because of the recent surge in diverse applications based on acoustic sensing. Prof. Roy's research focuses on developing hardware-software building blocks that enable new capabilities for this emerging future. In this talk, Prof. Roy will sample some of his recent projects. The topics will range from inaudible acoustics for security/privacy applications to on-body acoustic communication and wearable acoustic sensors. He will conclude this talk with a glimpse of his future projects targeting a stronger convergence of sensing, computing, and communications in tomorrow's IoT, cyber-physical systems, and healthcare technologies.
Nirupam Roy is an Assistant Professor in Computer Science at the University of Maryland, College Park (UMD). He received his Ph.D. from the University of Illinois, Urbana-Champaign (UIUC) in 2018. His research interests are in wireless networking, mobile computing, and embedded systems with applications to IoT, cyber-physical systems, and security. Prof. Roy is the recipient of the Valkenburg graduate research award, the Lalit Bahl fellowship, and the outstanding thesis awards from both his Bachelor's and Master's institutes. His recent research on "Making Microphones Hear Inaudible Sounds" received the MobiSys'17 best paper award and was selected for the ACM SIGMOBILE research highlights of the year in 2017. Many of his research projects have been featured in news media such as the MIT Technology Review, The Telegraph, and The Huffington Post.
