L. R. Welp studies how carbon dioxide, water vapor, and other gases move through the atmosphere, soils, and water using chemical 'fingerprints' called stable isotopes. This work spans monitoring atmospheric CO2 seasonal patterns, measuring greenhouse gas emissions from wetlands and agricultural land, and developing instruments and methods to track water and carbon cycling in critical zones (the layer of Earth's surface where rock, soil, water, and life interact). The research combines field measurements, sensor development, and data analysis to better understand climate feedbacks and landscape-scale environmental processes.

Publication output peaked around 2019 and has generally declined since, settling at a lower but steady rate of roughly 3-6 papers per year in recent years.
