Timothy (Tim) P. Marshall is a renowned meteorologist, engineer, and veteran storm chaser whose field research has shaped modern understanding of tornado behavior and structural damage. With decades of on-the-ground experience documenting severe storms, Marshall has contributed significantly to improving post-disaster assessments, engineering standards, and public safety guidance. His work bridges meteorology and structural engineering to identify how buildings fail and how they can be strengthened, making him a leading voice in tornado resilience and severe weather risk reduction.
