I'm a crop physiologist studying cereal crops. My current interests are crop physiology in fields (i.e. source-sink dynamics, nitrogen use efficiency, farming systems, etc.) using various statistical/data tools. Phenotypic plasticity and plant adaptation against environmental changes are also my interests. I’m always interested in programming (i.e. R, Python) for data science, and advanced SQL for big data analysis.

Easily draw light spectrum curves. I'll share a simple R code to create light spectrum curves.

Data normalization improves scale uniformity and enhances visualization interpretability. I introduce several methods for data normalization.

#Agrivoltaic conference in June 2024. In shaded environments, various studies on crop physiology are available without the need for additional shading installations. Agrivoltaics also makes it an energy-efficient approach in crop science. I love this concept. pic.twitter.com/OiDtyKUxAC

Solar Farm 2.0 #SCAPES Crops Research @ University of Illinois at Urbana-Champaign.
Last season, I altered the sources-sink strength of sorghum and soybean and collected valuable data. This upcoming season, I will analyze the genotypic variance of soybeans in response to shading. pic.twitter.com/76EqBF8kuB

Solar Farm 2.0 Crops Research at UIUC. This is one of my researches I've been involved, and my main interest lies in understanding how shading affects the main yield components and determining the best strategy for managing crop growth under solar panels (https://t.co/ztp25lHCky)

Source-sink manipulation was performed on sorghum by removing alternate leaves throughout the entire canopy and half of the head 10 days after flowering, as referenced in Gambín and Borrás (2007). How does sorghum grain weight respond to the change in assimilates? pic.twitter.com/omR7oDQTO8
