Welcome To the Lab!

Our lab is working to develop the next generation of high-performance computational tools that can allow for realistic simulation of plant systems in order to better understand how plant structure and function impacts biophysical processes across scale. We combine novel experimental and modeling approaches to conduct basic and applied research in plant productivity and water-use efficiency.

Our research is centered around the Helios 3D simulation software, which is developed and maintained by the lab. Helios is a C++ API that manages 3D model geometry and associated data, and has numerous model plug-ins, e.g., radiation, transpiration, growth, LiDAR, and others. Learn more here.
