Welcome to the Lab!

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

Open Positions

We will be recruiting students to start summer-fall of 2026. See the Join Us page for more information.

Software

Helios

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, photosynthesis, LiDAR, and others. Learn more here.

PyHelios

Harness the power of Helios in Python! Learn more here.

PhoTorch

PhoTorch is Python-based software for robust fitting of photosynthesis and stomatal conductance models based on leaf-level gas exchange data.

PhoTorch is open source software that can be downloaded at www.github.com/GEMINI-Breeding/photorch.
