First-author paper on adaptive batching of IoT workloads at the edge, trading latency against throughput and resource cost.

Evaluation of CareDEX, an NSF-funded data exchange that lets senior-care facilities share critical resident information with first responders, in a live disaster drill.

Technical report on the privacy-cognizant IoT environment built for the DARPA Brandeis program.

Turns an organization's existing Wi-Fi infrastructure into a source of occupancy and exposure insight during a pandemic, with privacy protections that prevent revealing any individual's movements.

Experience report on moving the DARPA-funded TIPPERS privacy-preserving IoT platform from a university testbed to testing in the U.S. Navy's Trident Warrior exercises.

Uses Intel SGX to process spatial time-series data securely while hiding access volumes and enabling verification of results.

Journal version of IoT Notary: tamper-evident, cryptographically verifiable records of what a smart environment's sensors captured and under which policy, so compliance can be checked independently after the fact.

Sole-author overview of my doctoral research on privacy-preserving data collection and sharing in smart spaces.

Prevents eavesdroppers from inferring residents' activities from the timing and volume of smart-home traffic, with verifiable guarantees that devices follow the protocol.

A privacy-enabled sensing platform supporting COVID-19 applications such as occupancy monitoring and exposure awareness.

Design of middleware that enforces privacy policies when IoT sensor data is shared with applications.

Preprint describing oblivious, privacy-preserving COVID-19 mitigation strategies built on organizational Wi-Fi data.

Best Paper Award. Introduces sensor data attestation for smart spaces: users and auditors can verify that data was captured according to declared policies.

Demonstration of a system that maps high-level application requests onto heterogeneous sensors in smart buildings.

A verifiable communication scheme that hides smart-home device activity from network observers; the conference precursor to Canopy.

Middleware that keeps IoT data flowing during network failures by combining software-defined networking with edge cloud resources.

A multi-network architecture for community-scale IoT safety and alerting that stays available when individual networks fail.

Low-cost IoT sensing and alerting for community safety, originating from the SmartAmerica Challenge.

Patent on a side-channel (differential power analysis) technique for extracting cryptographic keys.
