Youhua Ran
2025 WDS Data Stewardship Award Recipient
Youhua Ran is a Geographer specializing in permafrost mapping. He has systematically compiled a global dataset of ground-based permafrost observations through extensive collaboration, and by integrating these data with remote sensing, has developed a new generation of high-quality permafrost maps for the Qinghai–Tibetan Plateau and the Northern Hemisphere. His work provides a critical foundation for understanding permafrost distribution, assessing its changes and impacts, and supporting ecological conservation and cold-region engineering planning. Details of these data products can be found here: more DOI links here and here.
Youhua has also made foundational contributions to the integration and open sharing of geographic science data in China. As the academic secretary-general, he played a key role in organizing and coordinating the data release of the Heihe Watershed Allied Telemetry Experimental Research (HiWATER) project—one of the most comprehensive remote sensing experiments in China over the past decade. He has actively contributed to data quality assurance through methods such as observational data reconstruction, remote sensing product validation, and participation in data review processes. He led the development of the national standard for validating the accuracy of land cover remote sensing products and physical informed machine learning approaches to reconstruct time series of permafrost observational. He also serves as a data reviewer for the National Tibetan Plateau Data Center (TPDC) and the journal Scientific Data.
Micheal Arowolo
2025 WDS Data Stewardship Award 2nd Place
Prof. Micheal Olaolu Arowolo is an Assistant Professor of Health Informatics at Xavier University of Louisiana. He holds a Ph.D. in Computer Science with a focus on health data analytics and has served as a Postdoctoral Researcher at the University of Missouri. His research centers on data-driven approaches to health disparities, artificial intelligence, and data stewardship practices in public health. Prof. Arowolo has contributed significantly to data science education, mentoring, and the ethical management of health data, with multiple peer-reviewed publications and recognitions, including being listed among the world’s top 2% scientists. He remains committed to advancing equity and excellence in health informatics and data stewardship.
Bhaleka Persaud
2025 WDS Data Stewardship Award 3rd Place
Bhaleka Persaud is a Research Data Management Specialist at the University of Waterloo, driving scientific data stewardship for Global Water Futures (GWF) and other research projects in the Water Institute and the Department of Earth and Environmental Sciences. Bhaleka mentors’ researchers at all levels, shapes long-term data strategies, and builds collaborative data communities. She spearheaded the integration of the Water Institute’s researchers data into the Federated Research Data Repository, making it openly accessible to all. As part of the GWF, she also led the development of tools and resources—such as a data management template for water research, which is embedded within the Digital Research Alliance of Canada DMP Assistant—and contributed to training efforts through webinars, workshops, and peer-reviewed publications. These initiatives have strengthened FAIR (Findable, Accessible, Interoperable, Reusable) research data practices across the GWF program and will continue to benefit the scientific community in Canada and beyond.
Prior to her academic career in Canada, Bhaleka served as Chief Hydrometeorological Officer for the Government of Guyana and represented the country as its Permanent Representative to the World Meteorological Organization, supporting both national and global efforts in weather, climate, and water data management. She brings a diverse, interdisciplinary perspective shaped by her Guyanese roots, which continue to inspire her inclusive and collaborative approach to environmental data stewardship. She holds a BSc in Physics from the University of Guyana, MSc in Weather, Climate, & Modelling from the University of Reading and a PhD in Geography from Wilfrid Laurier University.
“The WDS Award introduced me to an enormous community of data scientists and professionals and gave more meaning to FAIR and CARE principles and their downstream value on environmental insights and applications than I’d ever have imagined.” -Robert Redmon, 2013 Award Winner
Previous Winners
Ethan Welty (2020) is a glaciologist specializing in the analysis of glacier time-lapse photographs. He also works as a scientific data and software consultant for organizations such as the Cascadia Field Station of the United States Geological Survey, Catalyst Cooperative, and the World Glacier Monitoring Service (WGMS, WDS Regular Member).
For the WGMS, Ethan spearheaded the effort to assemble, clean, and document version 3 of the global Glacier Thickness Database (GlaThiDa)—a major advance in the compilation of glacier ice thickness observations, which are fundamental to glacier monitoring and research. In the process, he established a continuous development environment for GlaThiDa to automatically record and verify edits and additions to the dataset as it changes over time. The environment is based on open-source metadata formats and software tools, and is described in https://doi.org/10.5194/essd-12-3039-2020.
Libby Liggins (2019) is an Associate Professor at Massey University and a Research Associate of the Auckland Museum Tāmaki Paenga Hira in Aotearoa New Zealand. Dr. Liggins leads the Ira Moana – Genes of the Sea – Project that is delivering a searchable metadatabase for New Zealand’s genetic and genomic data. The metadatabase aims to ensure the stewardship of genetic data resources, creating opportunities for data synthesis, helping manage data reuse, and informing future research directions for New Zealand.
