This study evaluated multispectral and hyperspectral vegetation indices to estimate wildfire severity in the 2022 Sierra de la Culebra fire. Field Composite Burn Index data were correlated with satellite-derived indices. Results showed hyperspectral imagery provided more accurate severity estimates, particularly using Cellulose Absorption Index and Red Edge indices.

This study explored whether satellite remote sensing can estimate black truffle mycelium biomass. Optical vegetation indices showed limited results, while Sentinel-1 radar backscatter had significant correlations, especially in spring. Findings suggest radar data capture soil moisture dynamics linked to fungal activity, offering a promising tool for sustainable truffle orchard management.

This study developed a real-time IoT-based system to optimize fishway performance in fragmented rivers. Using sensors, PIT-tag tracking, and machine-learning models, it links climate triggers with hydraulic controls. Adaptive sluice-gate regulation improved fish passage efficiency by 166% without reducing hydropower output, offering scalable, sustainable river management.

The speaker explains how hyperspectral satellites can detect invisible methane emissions, a major driver of climate change. Their research integrates data from multiple satellites to create a continuous global monitoring system capable of identifying leaks in real time, enabling rapid mitigation and transforming satellite technology into a tool for planetary sustainability.

Bur Oak Blight threatens Iowa’s most iconic tree. Current detection is slow and often too late. This research uses leaf-level reflectance and satellite imagery to identify early, invisible signs of infection across millions of trees. The approach enables rapid mapping of blight severity and helps protect Iowa’s ecological and cultural heritage.

Sunny-day flooding is becoming common in coastal North Carolina. Sensors revealed 65 flood days per year, and water-quality tests showed fecal contamination up to 100× above closure standards. A new computer model tracks how contaminated floodwaters move, helping identify hotspots and supporting safer water-quality advisories and flood-defense planning.

This research develops stable-isotope tools to measure how microbes—the Earth’s “lungs”—breathe CO₂ in and out. Microbes are massively abundant and shape global climate. Findings show deep subsurface environments slowly emit CO₂, a process that may influence future climate dynamics as human-driven environmental changes accelerate.

My research uses artificial intelligence to detect water pollution by analysing DNA traces left by aquatic species. Instead of relying on visual signs or costly expert identification, supervised machine learning reads species patterns to determine water quality. The method is faster, cheaper, and more accurate than traditional analysis.
