His PhD research was funded by a NASA Earth and Space Science 2010 Fellowship (NNX10AN72H) for his proposal titled "Fire Type Classification in the Brazilian Legal Amazon" and previously was funded by a NASA biodiversity grant (PI Prof. Mark Cochrane). His research responded to the NASA Carbon Cycle and Ecosystems science focus area by developing methods to classify MODIS active fire detections as deforestation fires, forest fires, disturbed forest fires, or maintenance fires. The spatio-temporal distribution of fire types over a eight year period (2003-2010) was documented and hypotheses concerning the impact of drought and disturbed forest on annual fire type proportions across the Brazilian Legal Amazon addressed.
