  • Hello everyone,  I have recently started my PhD in Epidemiology and have been interested in complex systems dynamics for a while. My background is in public health and biostatistics. I took an introductory summer course three years ago in complex systems. However, I was wondering if anyone has a recommendation in what courses should I take to embed myself in the field. I have experience in R programming and other statistical softwares, so I do not know if I should start first by getting acquaintance with the programming part or it, or if I should take a course that focuses more in the theoretical aspects of complex systems first.    Thanks and best,    César
  • I received a question recently from someone asking for advice on how to properly scope out a systems project. Here are some personal thoughts on things that are useful to consider. When starting out on a systems project, one of the most important things to consider is project scoping. Many projects have had to overcome "scope creep", the tendency to build a model that includes everything. The problem with this type of model is that, because the model itself is so complex, it makes it much harder to understand why certain behaviors are arising, and therefore, if the behavior of your model is accurate or due to errors in the model,the data, or your assumptions. The difficulty with proper scoping of a systems model is that the systems being studied are often poorly understood due to their complexity. We often don't know all the feedbacks, non-linear relationships, tipping points, or other such features before starting, or how to quantify them - it's the purpose of modeling to learn...
  • Welcome to healthmodeling.org! The primary goals of this site are​ to: facilitate the education of new researchers; ​ connect domain and modeling experts; and ​encourage collaboration and partnerships among modelers and substantive experts. To accomplish these goals, this site has a number of features. Some of the central ones are: The Models tab allows you to share simulation models. This can be done to demonstrate key types of health behavior, to explore model design techniques, to teach elements of system science, or for any other purpose. The Lectures tab allows you to share lectures you have made, or lectures you have found online. Partnerships and Funding Announcements are meant to help find collaborators, student modelers, or modeling employment opportunities. Communities is a place to find other people and material around a specific sub-topic of health modeling. The Forum is a place for discussion of a number of topics, getting insight from...
