Group Leader

Crop Sciences department greenhouses.Laura Christianson, Ph.D., P.E. founded and led the Illinois Drainage Research and Outreach Program (I-DROP lab) at the University of Illinois. She was promoted to Associate Professor with indefinite tenure in August 2022 and resigned from the University of Illinois in December 2022. With a background in agricultural engineering, she formerly worked on the design of woodchip bioreactors for removal of nitrate from point and non-point sources as a research engineer, studied options to improve ditch drainage water quality in the Mid-Atlantic, and has done research on drained dairy pastures as a Fulbright Fellow in New Zealand. She is a licensed professional engineer in the state of Illinois. Dr. Christianson was awarded the American Society of Agronomy’s Environmental Quality section 2018 Inspiring Young Scientist Award and the ASABE’s Larry W. Turner Young Extension Professional Award in 2020.



MW at DS Farm_cover cropMichael Wallace oversees the I-DROP Water Quality Laboratory and assists with in-house lab operations. He joined the lab in March 2020 with more than twenty years of experience in the field of water quality and applied research in Illinois. He also provides critical field support at research sites across the state.


KG at DS Farm_wheatKristin Greer is a Senior Research Specialist with emphasis on agronomy and environmental quality. She joined the I-DROP Lab in April 2020 after having worked in crop production and nutrient management research for almost twenty years. She is a University of Illinois graduate, managing field research experiments and day-to-day soils lab operations in coordination with graduate students and other lab members to ensure project goals are met in an efficient and timely manner. Outside of work, she farms approximately 600 acres of corn and soybeans with her husband. Her primary I-DROP activities involve the Dudley Smith Farm and associated projects.



Postdoctoral Associates

Alves_2021 Farm Progress Show Dr. Luciano Alves has been performing research on water quality in agricultural systems for 10 years with a particular emphasis on modeling and remote sensing technologies for managing and monitoring water and the vadose zone. His current research areas are on the role of vadose zone and water resources at agricultural systems, vulnerability and risk assessments, automation, and environment, focusing on techniques of computation processing and machine learning. He has a passion for teaching, with experience in teaching middle and high school, college-prep, undergraduate, and graduate students. He started with the I-DROP Lab in May 2020.CarolinaDiazGarcia_202105



Dr. Carolina Díaz García joined the I-DROP Lab in April 2021. She is a Civil Engineer, and she did her PhD at Universidad Politécnica de Cartagena in Spain (spring 2021) about denitrifying woodchip bioreactors for treatment of saline agricultural effluents and brine. Dr. Díaz García will be managing and helping to lead the multi-state NRCS Conservation Innovation Grant focused on bioreactors and saturated buffers.
