David M. R. Hyman
My work focuses on mathematical applications in volcanology and hazards studies.
My main expertise includes the analysis and numerical solution of dynamical systems (especially nonlinear PDEs) as well as probability theory. I have applied these techniques to models of geophysical flows (e.g., lava and debris flows, dome degassing), developing probabilistic volcanic cloud detection and characterization methods, and analysis of probabilistic hazards maps.

Pulsing in the Ahu‘ailaʻau pond-spillway system during the 2018 Kilauea Eruption: A dynamical systems perspective
During the 2018 Kīīlauea lower East Rift Zone eruption, lava from 24 fissures inundated more than 8000 acres of land, destroying more than 700 structures over three months. Eruptive activity eventually focused at a single vent characterized by a continuously fed lava pond that was drained by a narrow spillway into a much wider, slower channelized flow. The spillway exhibited intervals of ‘pulsing’

Toward next-generation lava flow forecasting: Development of a fast, physics-based lava propagation model
During effusive volcanic crises, the eruption and propagation of lava flows pose a significant hazard to nearby populations, homes, and infrastructure. Consequently, timely lava flow forecasts are a critical need for volcano observatory and emergency management operations. Previous lava flow modeling tools are typically either too slow to produce timely forecasts, or are fast, but lack critical as
