Check our first attempt at providing a proof-of-concept carbon “reanalysis” product that harmonizes carbon pools (leaf, wood, soil) and fluxes (GPP, Ra, Rh, NEE) across the CONUS using sequential data assimilation. Click here.
We are looking for motivated students with a strong background in statistics and computer coding to work on interesting data fusion crop modeling projects. Please contact me to learn more about the available positions
Check out this exciting work by Marissa Kivi, which uses Ensemble Kalman Filter to fuse soil moisture measurements into APSIM. Marissa showed constraining upstream estimates of soil moisture in APSIM results in substantially higher model accuracy and lower uncertainty in estimates of nitrate leaching. Click here.
Our latest publication tilted "A comprehensive uncertainty quantification of large-scale process-based crop modeling frameworks" is now formally accpeted and can be viewed Click here.
Congrats to Marissa Kivi for wining the Kraft/Frerichs graduate fellowship award. Well deserved !
A grant proposal led by our group was awarded $200k by CHS foundation to develop a precision agriculture talent pipline. This program aims to ‘even playing field’ for young and brilliant under-represented minorities seeking for an opportunity in precision Agriculture.

The long-term vision for our lab is to synthesize, analyze and create new value from the rich data streams generated by all phases of agricultural production. We will work towards developing novel data-driven approaches at the interface of computer science, statistics and crop science with the goal of improving and protecting our food system. In addition, we are always excited to welcome new graduate and undergraduate students with research interests aligned with the focus of the lab.
In this project, we are leveraging high performance computing to explore the impacts of different managment decisions in cover crop implementation across the state of Illinois.View Project
In this project, we are exploring the impact of RS soil moisture assimilation in APSIM model by expanding site-level soil moisture assimilation to more 20 site x year.View Project
In this project, we are exploring the use of earth observations (LAI and NDVI) for calibrating crop model parameters through different Bayesian optimization schemes (site-level, hierarchical, global).View Project
We are interested in assimilating in-situ soil moisture and soil temperature data obtained from soil sensors into APSIM, a robust process-based crop model, to see if the model is better able to predict soil N and yield at Energy Farm when compared to a model run without data assimilationView Project
In this study we use a multi-model regional crop simulatin platform to study the contribution of different sources of uncertainty in total variance simulated around crop yield and nitrate leaching for corn and soybean.View Project
Digital agriculture is concerned with the use of digital technologies for understanding underlying processes and solving agricultural issues. The ultimate goal of the Digital Agriculture course is to help students develop an understanding around three main components in digital agriculture including:
1) Statistical modeling and machine learning
2) Process-based crop modeling and
3) Remote sensing, where they all revolve around crop physiology and production.
In this course students will start by learning the fundamentals of crop physiology and familiarizing themselves with the current major issues around crop production in large. Then, students will learn about three powerful tools including statistical modeling, process-based modeling and remote sensing to addresses those challenges. This section is restricted to online programs only.
