We are developing a digital twin model that integrates multiple data sources to enhance public health decision-making in Texas. This tool will be applied to the long-term study of respiratory diseases, sexually transmitted diseases, vector-borne diseases, opioid transmission, and chronic diseases.
We are training neural networks to augment epidemiological models by improving parameter estimation, identifying abnormal trends, and enhancing the models’ data-driven capabilities.
We are conducting infectious disease model simulations using what-if scenarios for COVID-19, Influenza, and RSV at national, state, and city levels to support public health agencies in epidemic preparedness and evaluating the impact of interventions. 
We are employing diverse optimization techniques to address the optimal control problem and reduce overall epidemic costs—encompassing both infection-related and intervention expenses. Our approach integrates rigorous theoretical methodologies with data-driven strategies.

TEPHI is a network of public health professionals and resources that will ensure the state is at the forefront of pandemic readiness and response to keep Texans safe and the economy strong.
The TX-APCD includes medical, pharmacy, and dental claims, as well as eligibility and provider files, collected from private and public payors. It will contain administrative claims information on approximately 60% of all covered Texans, representing nearly 100% of medical claims regulated by the state.
Insight Net is a national network of centers working to improve our collective ability to understand, predict, prepare for, and respond to infectious disease threats through collaboration between analytic experts and public health departments..
The SMH pathogen-specific projections provide real-time modeling evidence aiming to support ongoing public health needs. SMH currently produces projections for COVID-19, seasonal influenza, and Respiratory Syncytial Virus (RSV), each addressing different public health questions and uncertainties.
