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, with a focus on empirically based modeling of HIV transmission. It is a ‘’hands-on’’ course, using the EpiModel software package in R (

EpiModel 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 several types of epidemic models: deterministic compartmental, stochastic individual-based, and stochastic network models. Resources include simple models that run in a browser window, built-in generic models that provide basic control over population contact patterns, pathogen properties and demographics, and templates for user-programmed modules that allow EpiModel to be extended to the full range of pathogens, hosts, and disease dynamics for advanced research.

This course will touch 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 EpiModel prototype model (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, students are recommended to review the materials on the PREP page. Each day’s materials will be posted on the respective page linked above.

2021 Course Information

The 2021 Network Modeling for Epidemics course will be offered from Monday, August 2 to Friday, August 6

Due to the travel restrictions associated with the COVID-19 global pandemic, we will be offering NME 2021 as a remote-only course through Zoom. The lectures provide an overview of the theory, methods and software instruction – they will be recorded and posted after the session for asynchronous access. If the COVID reopening process allows, we may include optional in-person meetings on the University of Washington campus in Seattle, for those who wish to participate.

Labs provide hands-on practice with the software, and will be organized around specific tasks. Traditionally we have run these as group labs, with 5-10 people per group, loosely organized by domains of research. We will endeavor to replicate this approach using Zoom “breakout rooms”. However, these labs can also be completed individually, and/or asynchronously. The instructions and materials will be placed online for access in both real time and later review and use.

Our course will run in two sessions each day:

Course Syllabus

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.

Day Topics
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

Application Information

  • May 1, 2021: Application deadline.
  • June 1, 2021: Application decisions will be made and announced.
  • July 1, 2021: Registration deadline. Late registration is possible through July 15 with a late fee of $250.
  • A wait list will be established along with rolling admission through June 15, 2021 if space allows.

Course fee is $750. We offer a limited number of fee waivers for pre-doctoral students or for attendees from low income countries. These cover waiver of the registration fee only.

Returning Students

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.
