The XIE (X-Scale Irrigation & Earth Observation) Lab at the University of Oklahoma is seeking one PhD student and two postdoctoral researchers to join the newly funded Re-Analysis of Water for Society (RAWS) project. The lab, led by Assistant Professor Yanhua Xie, specializes in geospatial AI, remote sensing, and Earth observation to address challenges in agricultural irrigation, land use mapping, and water resource management. Research in the lab integrates multi-source geospatial data, artificial intelligence, and cloud computing to develop scalable solutions for sustainable food production and drought resilience. The available PhD position focuses on remote sensing of agricultural land and water use, while the two postdoc positions target agricultural irrigation mapping and land use/cover mapping, both leveraging geospatial AI. The lab collaborates with water resource agencies and agricultural stakeholders, providing a dynamic environment for interdisciplinary research in environmental science, geography, and computer science. Applicants for the PhD position should have a strong background in remote sensing, geospatial science, environmental science, geography, or related fields, with experience in geospatial data analysis and AI/ML preferred. Postdoc candidates must hold a PhD in a relevant discipline and demonstrate expertise in geospatial AI, agricultural irrigation mapping, or land use/cover mapping. All candidates should possess strong research skills and a keen interest in the lab's focus areas. Funding is provided through a newly funded project, with standard university support expected for PhD students and postdocs. Specific details on stipend or tuition coverage are not specified. Applications are reviewed on a rolling basis until the positions are filled. To apply, PhD candidates should email a cover letter and CV to Dr. Yanhua Xie ([email protected]) with the subject 'PhD: Ag Land/Water Use'. Postdoc applicants should submit a cover letter, CV, and contact information for three references to the same email with the subject 'Postdoc: Ag Irrigation'.
