Data Scientist

Most recently, I completed my internship with Climate Corporation, where I was responsible for

statistical and spatial data analysis, model building, and validation. Before this, I had a role

where I was responsible for data analysis and report writing of on-farm soybean trials across SD

(Combine Yield Monitor data). I developed yield map and treatment effect overlaying LiDAR

and SSURGO Soil data (using R, QGIS, ArcMap and Surfer). I have worked with R

programming extensively, in addition to various other technologies, adapting quickly.

Research Assistant

Statistical Analysis and report writing of wheat quality data: wheat samples collected

from growers across the state of South Dakota during 2006 to 2010 were analyzed for

protein, dough quality along with wheat type, cultivar and cultural practices.

Assisted on several cover crop experiments to establish experiment, collect in season

samples and harvesting.

Graduate Research Assistant

Nitrogen and water rate study on winter wheat yield and quality:

Used N, N15, C and C13 (Mass spectrometer), ammonia, nitrate (segmented flow auto

analyzer) of soil and plant for nitrogen and water stress effect quantification.

Crop reflectance data (MSR Crop Scan unit), biomass, and grain yield were used for

model building.

Brabender Farinograph data were used for dough quality test.
