I am a Research Scientist in the Ainsworth Lab at the University of Illinois, working within the RIPE project at the Institute for Genomic Biology. My research program integrates genetics, remote sensing, and computational biology to improve soybean canopy architecture for greater photosynthetic efficiency and yield.
I developed over 200 backcross lines and CRISPR-edited soybean targeting the narrow leaf (ln) locus to optimize leaf area index. I combine UAV and satellite imagery with machine learning to predict plant traits at scale, and use these predicted phenotypes for QTL mapping and phenomic selection. My earlier work characterized transcriptomic responses to flooding and drought stress in soybean, and transpiration dynamics in cereal crops.
Understanding and improving crop productivity through physiological and molecular approaches.
Developed 200+ BC3 near-isogenic soybean lines and CRISPR-edited GmJAG1 knockouts to dissect how narrow leaf shape reduces leaf area index and improves light distribution through the canopy. Two U.S. provisional patents filed.
Using multispectral UAV and satellite (Sentinel-2, Planet) imagery with XGBoost, random forest, and SVM models to predict peak LAI and yield across multi-environment soybean trials with hundreds of genotypes.
Applying mixed-model GWAS to ML-predicted BLUPs from remote sensing data to identify genetic loci for canopy traits. Identified 70 significant SNPs (29 independent signals after LD pruning) replicated across field locations.
Integrating spectral reflectance data into genomic prediction frameworks. Satellite-derived phenomic selection achieves prediction accuracies comparable to UAV platforms, enabling scalable breeding applications.
RNA-seq and single-cell transcriptomic analysis of GmJAG1, the narrow leaf gene. JAG1 acts as a transcriptional repressor of cell cycle regulators including D-type cyclins and histone deacetylases in leaf primordia.
Characterized overlapping and distinct transcriptomic and hormonal responses to flooding and drought in soybean. Earlier work on nocturnal transpiration dynamics and circadian control of water use in cereal crops.
