What I did

• Second-authored DualPI2 for Mahimahi (ACM SIGCOMM CCR), introducing an L4S-capable DualPI2 emulator and a statistically grounded methodology for improving fidelity to kernel-space behavior.
• Quantified Mahimahi DualPI2 fidelity against the Linux kernel implementation using time-series analysis and robust nonparametric tests, identifying statistically significant gaps in packet timing and shaping.
• Engineered a concurrent network experimentation system using Linux namespaces, traffic-control, and virtual-networking primitives, enabling parallel collection with under 5% cross-run variance.
