operational deployments

Operational infectious disease forecasting and scenario modeling deployed through ACCIDDA's computational infrastructure.

Scenario Modeling Hubs

Multi-model scenario projections produced by the Scenario Modeling Hubs are used by the CDC Center for Forecasting and Outbreak Analytics (CFA) and the Advisory Committee on Immunization Practices (ACIP) to inform vaccine policy and pandemic preparedness decisions.

I develop and maintain ACCIDDA’s operational models for the Flu and COVID-19 Scenario Modeling Hubs and contribute to the computational infrastructure that supports multi-round scenario projections.

Flu Scenario Modeling Hub

Lead model developer for ACCIDDA’s influenza scenario projections.

  • 2026/27 operational round — supervising an undergraduate student in a scientific overhaul of the ACCIDDA flu model
  • 2025/26 operational round — leading scientific overhaul of the ACCIDDA flu model
  • 2024/25 operational round — initial model development and pipeline integration

COVID-19 Scenario Modeling Hub

Data assimilation and modeling support for ACCIDDA’s COVID-19 projections.

  • 2025 health heterogeneities round — data cleaning, assimilation, and scenario analysis

Other Operational Work

Hib Vaccination Modeling (Navajo Nation)

Technical supervisor for an age- and immune-status-structured Haemophilus influenzae type b (Hib) model evaluating the impact of long-running vaccination programs in the Navajo Nation. Managing PhD students through model implementation, calibration, and policy analysis.

Infrastructure

This operational work directly informs the development of FlepiMoP2, OP Engine, and OP System, which compose into a declarative modeling stack: researchers specify models via OP System’s specification language, the compiler produces validated model objects consumed by OP Engine’s operator-partitioned solver, and FlepiMoP2 orchestrates batch scenario campaigns. This stack will serve as the modeling infrastructure for the 2026/27 flu round, the COVID-19 round, and the RSV round.
