Network Modeling for Epidemics (NME) is a 5-day short course at the University of Washington that provides an introduction to stochastic network models for infectious disease transmission dynamics. It is a ‘’hands-on’’ course, using the EpiModel software package in R.
EpiModel software provides a unified framework for statistically based modeling of dynamic networks from empirical data, and simulation of epidemic dynamics on these networks. It has a flexible open-source platform for learning and building these models. While the software specializes in stochastic network modeling of epidemic dynamics, it also provides tools for deterministic compartmental (DCM) and stochastic individual- (or “agent-”) based models (ICM).
EpiModel resources include:
Simple models that run in a browser window (via
RShiny), with an interactive GUI and downloadable graphical
outputs. These tools reduce the barriers to learning the basic concepts
of epidemic modeling in each of the three frameworks (DCMs, ICMs and
network models), and are perfect for teaching in code-free environments
and real-time demonstrations.
Built-in generic models that provide basic control over population contact patterns, pathogen properties and demographics through standard coding scripts. These tools are designed to help users get started with EpiModel coding principles and run basic models.
Templates for user-programmed modules that allow EpiModel to be extended to the full range of pathogens, hosts, and disease dynamics needed for advanced research. These tools are designed to support research scientists and professional modelers.
The NME course provides an introduction to all of these resources. It touches on the deterministic and individual-based models, but its primary focus is on the theory, methods and application of network models. The course uses a mix of lectures, tutorials, and labs with students working in small groups. On the final day, students work to develop an advanced EpiModel prototype (either individually or in groups based on shared research interests), with input from the instructors. Students are required to bring their own laptop computer to the course.
Prior to the course, we recommend students review the materials on the PREP page. Each day’s materials will be posted on the respective page linked above.
If you would like to get started with EpiModel now, course materials
from 2021 are online for self-learning. An overview of the course can be
found below, and the course materials for each day are available online

Additional helpful materials may be found at the EpiModel website.

Lectures provide an overview of the theory, methods and software instruction – they are recorded and posted after the session for asynchronous access.
Labs provide hands-on practice with the software, and will be organized around specific tasks. Traditionally we run these as small breakout group labs, loosely organized by domains of research. The instructions and materials are placed online for access in both real time and later review and use.
The instructions and materials are placed online for access in both real time and later review and use.
Our course will run in two sessions each day:
The course uses mornings for lectures, and afternoons for labs with students working in small groups. On the final day, students have the option of developing an EpiModel prototype for their own research projects, with input from the instructors, which includes the EpiModel software developers.
|1||Introduction to epidemic modeling; Stochastic models for epidemics; Classical descriptive network analysis|
|2||Cross-sectional statistical network analysis (ERGMs); Dynamic statistical network analysis (STERGMs)|
|3||Simple epidemic models on networks; Epidemics in fixed populations with network dynamics independent of disease state|
|4||General epidemic models on networks; Epidemics in open populations, with interactions between networks, demographics and infection|
|5||Extending EpiModel for original research projects; Individual consultations on participant projects|
We encourage previous attendees with active modeling projects to apply to return for a refresher course. The EpiModel package has been significantly enhanced over the last few years. Returning students with active projects will have the opportunity to work with course instructors to address key challenges in the design of their network model code.
