Anna Mummert: Research

Research Interests

My current research interests are in the fields of mathematical biology and other applications of dynamical systems.

Epidemiological Modeling

• Modeling a pandemic flu outbreak focusing on determining why 2009 pandemic H1N1 flu has two peaks in the number of infected individuals, while seasonal flu only has one peak, using agent-based modeling. This project is part of the Marshall BioM2 project (NSF - UBM grant).
• Parameter estimation for epidemiological models of influenza. Studying the time-dependent transmission rate in stochastic and deterministic epidemic models. Statistical inference for discrete and continuous Markov chains.

Ecological Modeling

• Modeling the Midwestern United States prairie ecosystem using ordinary differential equations.

Selected Past Projects

• Epidemiology: (1) Modeling the influence of isolation and other mandates on controlling outbreak of infectious diseases, with a focus on optimal control measures. (2) Modeling the influence of media intervention on the severity of disease epidemics. (3) Discretizing the SI (susceptible-infected) epidemic model. (4) Modeling super spreading events of infectious diseases, with a focus on SARS.
• Biological: (1) Modeling reslin in insect joints. This project is part of the Marshall BioM2 project (NSF - UBM grant). (2) Analysis of respiratory rates in freshwater mussels. This project was part of the Marshall BioM2 project (NSF - UBM grant). (3) Modeling antibiotic resistant bacteria in rivers.
• Geometry: (1) Examining projective conics on the sphere.
