PhD candidate in Computer Engineering at Virginia Tech and founder of RGR Innovate LLC. This site highlights research, publications, software projects, and technical writing.
I work on Linux kernel instrumentation, eBPF observability, and Android and IoT security. Advised by Haining Wang and Randy Marchany, with 15+ years of mobile and platform engineering experience.
Computer Security
System and platform security work across Android, Linux, IoT, and defensive instrumentation.
eBPF and Linux Kernel
Kernel tracing, observability, benchmarking, and overhead-aware instrumentation using eBPF.
Embedded and IoT Security
Systems work: measurement and engineering.
Bluetooth Low Energy Security
Systems work: measurement and engineering.
System Performance
Performance analysis, bottleneck discovery, and runtime tuning guided by measurement.
Network Security
Security analysis for networking paths, protocols, and connected devices.
Projects
Active work
ZeroDown
A zero-downtime IoT policy enforcement framework for MCU-class devices with OTA policy updates, runtime toggling, and embedded uBPF execution.
ActiveBlueSentry
An application-layer BLE security framework combining FSM enforcement and runtime eBPF policies for embedded-device threat detection.
ActiveeBPF tracing overhead analysis
