Program: PhD
Supervisor: Bing Lu
Education:
繚 M.Sc., Software Engineering, Universidad de Los Andes, Colombia (2023)
繚 M.Sc., Agricultural Sciences, Universidad de Pamplona, Colombia (2022)
繚 B.Sc., Agricultural Engineer, Universidad Pedag籀gica y Tecnol籀gica de Colombia (UPTC), Tunja, Colombia (2014)
Research description/interests: Remote sensing, precision agriculture, UAV-based imaging, multispectral and hyperspectral remote sensing, crop monitoring, and GIS.
Biography: Alexandra Fajardo-Rojas is a Colombian Agricultural Engineer and PhD student in Geography at 911勛圖. Before joining 911勛圖, she worked as a researcher at AGROSAVIA, the Colombian Corporation for Agricultural Research, where she contributed to research on agricultural systems, water governance, and sustainable rural development. Her current research explores the application of remote sensing and geospatial technologies to agricultural systems, with a particular interest in UAV-based remote sensing, multispectral and hyperspectral imaging, field spectroscopy, and high-resolution crop monitoring. Through her research, she seeks to bridge her background in agronomy with emerging geospatial technologies to better understand and monitor crop conditions and support sustainable agricultural management.
