Overfitting with Miguel Mahecha | High-Dimensional Earth Observation Data for Biosphere Shifts

In this session of Overfitting with, we host Miguel Mahecha, Professor of Environmental Data Science and Remote Sensing at Leipzig University, for an in-depth conversation covering his scientific research and academic trajectory. The presentation explores the power of high-dimensional Earth observation data, introducing the Earth System Data Cube, interactive visualization tools like LexCube, and AI-driven workflows combining drone imagery and satellite data to monitor forest mortality and track the shifting global "Green Wave," followed by a personal discussion on his Colombian-German heritage, his transition from geoecology to machine learning, the lessons learned from nonlinear dimensionality reduction, and his approach to building interdisciplinary research teams, fostering student collaboration, and cultivating resilience in science. 00:00 - Introduction & Welcome 01:52 - Talk: High-Dimensional Earth Observation & Biosphere Dynamics 04:06 - Scaling Local Sensor Observations to Global Carbon Fluxes 08:14 - The Earth System Data Cube Concept & LexCube Visualization 13:40 - Deep Learning on Spatio-Temporal Cubes & Modeling Challenges 26:03 - Drone Imagery, Forest Mortality, & The DeadTrees Platform 35:40 - The Green Wave: Tracking Global Vegetation Center of Mass 38:17 - Technical Q&A Session 47:28 - Career Journey: Geoecology, Colombian Roots, & Nonlinear Dimensionality Reduction 58:36 - Interdisciplinary Research & Data-Driven Human Development Indices 1:01:40 - Career Q&A: Academic Resilience, Team Mentorship, & Scientific Visualization 1:19:44 - Closing Remarks
