Phenomics Workshop

A team of Purdue faculty in plant sciences has developed phenomics workshop to addresses the gap of limited educational opportunities available to professionals and students in the emerging field of crop phenomics.

In March 2017, Purdue hosted a module-based phenomics workshop targeted to crop research professionals and engineers involved in predicting yield and characterizing biotic and abiotic stress, as well as engineers involved in developing and using sensors and sensor platforms for application. This workshop was recorded and now available for purchase online.

Data-driven approach

Crop phenomics merges science and engineering into an intensely data-driven approach in agriculture that is a fast-growing area of resource investment.

Educational Opportunities

Limited educational opportunities exist for professionals and students to learn about phenomic approaches.
