**About the Editors**

### **Ana I. de Castro**

Dr. Ana de Castro is a tenured scientist at INIA working in digital agriculture systems and precision agriculture to address aspects of crop protection, e.g., early detection of pests and weeds, monitoring crop variability, and high-throughput crop phenotyping. She has published more than 40 articles in SCI journals (90% Q1). She has participated as PI and research member of 25 national and international research projects and has been invited as Guest Speaker in numerous conferences and workshops. She has a wide network of collaborations both national and international research centers and universities. She is an Editorial Board Member of *Remote Sensing* and leads the Special Issue "UAVs for Vegetation Monitoring". She was associate editor of the *Spanish Journal of Agricultural Research* and guest editor of the *Journal of Chemistry*. She has been awarded the Best Working Weed Science-2013; 2nd Best Oral Communication received in the 9th ECPA; Jose Luis Labrandero-2015; Premio del Articulo Agrario-2017; and Editor's Choice-2018 by *Remote Sensing*.

#### **Yeyin Shi**

Dr. Yeyin Shi is an assistant professor of agricultural information systems in the Department of Biological Systems Engineering at University of Nebraska-Lincoln. The goal of her research program is to develop and apply emerging sensing and information technologies, as well as state-of-the-art data science techniques to generate, gather, analyze, and manage data for actionable decision makings in row crop production and pasture management. The data generated by unmanned aircraft systems (UAS or UAV) are a major source of information in her research. In addition, she and her colleagues also go beyond sensing but incorporating sensing into actuation to use UAS for intelligent aerial applications. Dr. Shi is also passionate about college educations and has been part of the thrust in the development of precision and digital agriculture curriculum.

#### **Joe Maja**

Joe M. Maja is a Research Scientist at the Edisto Research and Education Center and a faculty of the Department of Agricultural Science. He provided the vision and expertise to develop a distinctive program for an Experiment Station called the Sensor and Automation Laboratory. His main research effort has focused on emerging technologies, small-unmanned aircraft systems, and mobile robotics. These collective efforts attempt to merge unmanned systems with other appropriate technologies to benefit a variety of agricultural disciplines. His research efforts have involved collaboration with colleagues within Clemson and externally both national and international universities or research institutes. He was elected as Chair of the Central Savannah Rivers Section of the IEEE organization and continues to be a member of the executive committee of the same organization. He has secured more than USD 2 million in extramural funding and has been active in securing federal and commodities funding.

#### **Jose M. Pe ˜na**

Dr. Jose M Pena is a Scientist at the Institute of Agricultural Sciences of CSIC and co-director of ˜ the tec4AGRO research group. His research focuses on the development and validation of geospatial technologies and digitization tools for precision agriculture and integrated pest management (IPM), with the aim of proposing new strategies to optimize crop protection and production for achieving more sustainable agricultural systems. He has participated in 20 research projects, which have resulted in the publication of about 100 SCI and outreach articles, 10 book chapters, and 120 conference contributions. He is honored to have received several distinctions, such as the Fulbright scholarship and the Pierre C. Robert award from the International Society of Precision Agriculture.
