Android Connectivity and Standardization Lead, 2022 - present

• Responsible for end-to-end system design and standardization of UWB and Bluetooth features for engineering and product, while advising senior leadership on strategic initiatives

• Lead for architecture, standardization, and protocol implementation of the cross-functional CSA/Aliro physical access control standard, working with the Android Wallet team for credentials/provisioning. Launching in 2025

• Lead architect for UWB ranging, and serving as Google’s primary delegate for standardization at the FiRa Consortium

Android Context / CHRE / CHPP Lead, 2019 - 2021

• Led efforts to enhance the CHRE platform, which runs on a low-power Always-On Coprocessor (AOC) and enables efficient sensing and context-aware applications on Android devices (e.g. Activity Detection, Crash Detection)

• Power lead for CHRE, achieving a 15% power saving by co-optimizing memory and processor speeds to workload

• Lead the design and implementation of the Context Hub Peripheral Protocol (CHPP) from the ground up. CHPP runs on CHRE and its peripherals (e.g. WiFi/BT, modem, GNSS chips), enabling CHRE to scale from same-chip architectures to the broader Android ecosystem, balancing scalability with resource constraints of internal/external stakeholders

• Bluetooth audio lead, pushing the envelope of BT SIG on hosts (iOS, watchOS, etc.) and accessories (AirPods, etc.).

Achieved close-to-lossless audio quality in favorable RF and over 10x reliability in adverse RF conditions while maintaining battery life by designing & delivering cross-functional features such as link-adaptive bitrate and packet types, packet-size-optimized VBR, adaptive ePA TX power, antenna diversity / beamforming algorithms, and cross-layer power optimizations

• OTA airtime, discovery, and audio simulation, measurement, and optimization across BT/BLE/WiFi applications, including A2DP (including low latency / spatial audio), HFP, AirDrop, AirPlay, and AWDL peer-to-peer (~NAN) WiFi, working with Audio, Codec, DSP, SEG (Silicon Eng), RF, Antenna, and Human Factors teams

• Lead for Bluetooth/WiFi demo feasibility and performance validation for new product announcement events

• Designed and delivered custom HW/SW systems and prototypes (e.g. a low-cost RF coexistence testing platform using off the shelf hardware and scripting costing < $2K each vs. $10s of K commercial solutions)

• Developed and evaluated LTE/WLAN/Bluetooth selection, interworking, and co-existence mechanisms for Broadcom LTE R10 solutions (TDD/FDD IDC, in/out-of-band interference/harmonics/IM3; BT-SIG/WCI-2, GPIO interfaces)

• 3GPP LTE and WiFi interworking functional specification, system design, and standards (SA2, CT1), encompassing operator requirements (WLAN interworking, ANDSF, WLAN_NS, Hotspot 2.0, RCS, ProSe, WiFi offloading, VoLTE)

• Led the HW / SW design and implementation of the Rice Orbit Sensor Platform, an open source Bluetooth body area platform (e.g. smartwatch, motion sensing, medical / ECG health monitoring applications). Used by collaborators in academia and industry.

• Utilized statistical learning on contextual information for predicting iPhone app usage / call usage / WiFi connectivity.

• Improved performance and usability of smarphones through sensing, network selection, and predictive energy management.

• Privacy-aware, long-term smartphone usage data collection and analysis, revealing long-term evolution of smartphone adoption / usage, including the impact of socioeconomic status.

System to enable and select between cellular and WiFi networks on Android based on predicted network conditions & device usage
