This article is a collaboration with John Peach, from Wild Peaches . John Peach is an applied mathematician who held a research position at MIT Lincoln Laboratory until retirement in 2020. As lead investigator of a team of physicists and mathematicians at MIT, he spearheaded development of an atmospheric lidar propagation model accounting for scattering, refraction, and object response. This technology enabled 3D mapping of Puerto Rico after Hurricane Maria to locate and assess damage, expediting recovery efforts. As part of the disaster relief program, he made three trips to assist FEMA on-site with model implementation, and co-authored the paper “To Expedite Roadway Identification and Damage Assessment in LiDAR 3D Imagery for Disaster Relief Public Assistance.”
