Hello! I am Ryan Bart, an Assistant Professional Researcher in the Sierra Nevada Research Institute at the University of California, Merced. My research explores the linkages and feedbacks between water, vegetation, and wildfire; with a focus on how these linkages vary with climate change and forest management practices. I was a born and raised in California, and after having lived up and down the state, I currently reside in Merced with my wife, Ana, and our two boys.


I am a developer for RHESSys, a process-based ecohydrologic model designed to simulate water, vegetation, nutrient, and fire processes. I also design and create tools to make modeling with RHESSys more user friendly, including the R package RHESSysIOinR.

If you are interested in learning more about how to use RHESSys, I am writing a book about how to install, setup, and run simulations using the model:

I also organize a RHESSys Conference which will be held this year on 1-2 May 2024:

Looking for someone to help integrate RHESSys into your own project? Please feel free to contact me. I am always open to new collaborative research opportunities.
