Nicholas Landry
I’m an Assistant Professor of Biology at the University of Virginia (as well as a courtesy faculty member in the School of Data Science) and I lead an interdisciplinary lab studying how networks and groups (higher-order interactions) affect the spread of diseases, information, and opinions. I use tools from network science, mathematical modeling, Bayesian inference, and open-source software.
My portfolio is a collection of some projects that I’ve worked on personally, professionally, and academically. For more about me, see my bio, CV, or list of publications. You can also take a look at my blog.
Research Interests
- The structure and dynamics of complex systems (particularly those involving higher-order interactions)
- Contagion spread (disease, opinions, etc.)
- Inference of network structure
- Open software
