Bruce Maggs
Duke University and Emerald Innovations, USA
Health Monitoring with Wireless Sensors and Machine Learning
Abstract: This talk introduces the Emerald health monitoring system, a new technology that automates health monitoring through innovations in wireless sensing and machine learning. An Emerald device in the home transmits low-power radio signals and records their reflections. The recorded data is then passed to the cloud for processing using neural network algorithms. The monitoring system can infer the movements, breathing, heart rate, falls, sleep apnea, and sleep stages of people in their homes — all without requiring them to wear any sensors. By monitoring physiological signals continuously, the system can automatically detect deterioration in health conditions, enabling early intervention and care. The talk will describe the underlying technology and present results demonstrating its promise in monitoring geriatric populations.

Invited Speakers

Manabu Tsukada
University of Tokyo, Japan
Cooperative Automated Driving Using Vehicle-to-Everything (V2X)
Abstract: Autonomous automatic driving is essentially a replacement for humans. It has the same limitations as human drivers because it uses onboard sensors and computers to drive based on localized information. Cooperative automatic driving is expected to achieve a level of safety and efficiency that has not been possible with human driving imitation by accurately perceiving a wide range of physical space through V2X communication. This talk will introduce the prospects of cooperative automated driving and the attempts of cooperative perception and cooperative planning implemented using Autoware, an automated driving software.

Towards Performant Networking from Low-Earth Orbit
Abstract: Upstart space companies are building massive constellations of low-flying satellites to provide Internet service. These developments comprise “one giant leap” in Internet infrastructure, promising global coverage and lower latency. However, fully exploiting the potential of such satellite constellations requires tackling their inherent challenges: thousands of low-Earth orbit (LEO) satellites travel at high velocities relative to each other, and relative to terrestrial ground stations.
The resulting highly dynamic connectivity is at odds with the Internet’s design, which assumes a largely static core infrastructure. Virtually every aspect of Internet design — physical interconnection, routing, congestion control, and application behavior — will need substantial rethinking to integrate this new building block.

In this talk, I will focus on topology design, while also briefly touching upon the other open networking challenges in this context. Coming to topology design, we posit that the high density of these new constellations and the high-velocity nature of such systems render traditional approaches for network design ineffective, motivating new methods specialized for this problem setting. We propose one such method, explicitly aimed at tackling the high temporal dynamism inherent to low-Earth orbit satellites. ploit repetitive patterns in the network topology to avoid expensive link changes over time, while still providing near-minimal latencies at nearly 2× the throughput of standard past methods.

I will also present Hypatia, a framework for simulating and visualizing LEO networks, that we built to enable broader research in this area. Using publicly available design details for the upcoming networks to drive our framework, we characterize the expected behavior of these networks, including latency and link utilization fluctuations over time, and the implications of these variations for congestion control and routing.

Speaker's Bio:
Debopam recently defended his PhD in computer networks at ETH Zurich (Network Design lab, Systems group), Switzerland. His research is focused on “new space” satellite networks, low latency terrestrial networks, and Internet architecture. His recent work on simulating and analyzing satellite networks won the Best Paper Award at ACM IMC 2020. He also received IRTF’s Applied Networking Research Prize 2020 ( for his work on satellite network topology design. Debopam worked as a research fellow at Max Planck Institute for Informatics (Germany) during summer 2019. Debopam earned his dual master’s degree in security and mobile computing from KTH Royal Institute of Technology (Sweden) and Aalto University (Finland). He earned his bachelor’s degree in computer science from Jadavpur University (India). For further details, please refer to his Web page:

Large-scale Automatic Depression Screening Using Smartphone Data
Abstract: Depression is a serious mental health problem that impacts the overall health of an individual, and incurs higher medical costs and mortality. Current depression screening relies on either physician administered or patient self-administered surveys. Such methods are burdensome, suffer from recall bias, and not suitable for continuous monitoring. The ubiquitous adoption of smartphones around the world creates new opportunities in automatic and pervasive screening of depression over large populations. In this talk, we will present our recent work and findings in this area, along with challenges and future directions.

Speaker's Bio:
Bing Wang is a Professor with the Computer Science & Engineering Department, University of Connecticut. She received a Ph.D. degree in Computer Science from the University of Massachusetts, Amherst in 2005. Her research interests are computer networking and distributed systems.
