Michelle Gierach
Michelle Gierach is a NASA Jet Propulsion Laboratory scientist who led development of a self-supervised machine-learning tool that fuses data from five satellite missions/instruments (including PACE and TROPOMI) to detect harmful algal blooms off Florida and California, published in AGU’s Earth and Space Science. The work is a ground-truthable Earth-observation analogue for remote biosignature-detection methodology (src-nasa-orbital-biosignature-algae-ai-2026-05). Co-authors include Kelly Luis (NASA JPL) and Nick LaHaye (Spatial Informatics Group).
