Gabriel Penedo

Environmental Computing · Machine Learning · Geospatial Systems

I am an environmental computing researcher with training in quantitative economics. My work examines how machine learning, geospatial systems, remote sensing, and field-generated data can be used to understand environmental systems and support real-world decision-making.

My current research focuses on the reliability of environmental AI, particularly how sensing conditions, preprocessing decisions, human data collection, and implementation choices influence what computational systems ultimately observe and report.

Current Research

I am currently working with Dr. Kala Fleming and Dr. Elizabeth Ondula on three interrelated projects spanning environmental computer vision, field-grounded AI, and geospatial decision systems.

Sliding-Window Instability in Environmental Object Detection

Studying how the origin of a sliding-window inference grid affects individual tree-crown detections while tile size, overlap, and model configuration remain fixed. The work examines reproducibility and implementation sensitivity in environmental object detection.

Field-Grounded Environmental AI

Investigating how field observations, structured annotations, drone imagery, and physical interventions can reduce ambiguity in environmental computer-vision workflows and produce more reliable inputs for machine-learning systems.

Geospatial Decision Systems for Green Infrastructure

Developing spatial data systems that integrate environmental, infrastructure, and community datasets to support green stormwater infrastructure analysis and real-world decision-making.

These projects are ongoing.
