Dr Mark A Finney is a Senior Scientist and Research Forester. He began his career as a seasonal wildland firefighter with the Bureau of Land Management and worked as an ecologist for Sequoia National Park before joining the U.S. Forest Service at the Missoula Fire Sciences Laboratory. His research has involved fire history and ecology, prescribed burning, modelling of fire growth, landscape fuel treatment design, wildfire risk analysis, and laboratory and field experiments on the physics of wildland fire behaviour. Dr Sara S McAllister is a Research Mechanical Engineer for the U.S. Forest Service at the Missoula Fire Sciences Laboratory. She earned her PhD in Mechanical Engineering from the University of California, Berkeley, where she studied material flammability in spacecraft and co-authored a textbook on combustion fundamentals. Her current research includes understanding the critical conditions for solid fuel ignition, flammability of live forest fuels, ignition due to convective heating, and fuel bed property effects on burning rate. Jason M Forthofer began his career with the U.S. Forest Service as a seasonal firefighter and now works as a Mechanical Engineer at the Missoula Fire Sciences Laboratory. His research includes numerical, field and laboratory studies of heat transfer and fluid flow relating to wildland fires. Results of his work include improvements to fire shelters and safety zone size guidelines and development of fire tornado training material, operational wind models and a fire spread model. Jason is a qualified Division Supervisor for wildland fire suppression in the USA. Dr Torben P Grumstrup is a Research Mechanical Engineer at the U.S. Forest Service, Missoula Fire Sciences Laboratory. His introduction to wildland fire was working as a Forest Service seasonal wildland firefighter on engine, helitack and heli-rappel crews. Torben has diverse engineering experience, ranging from particle accelerator engineering to laser spectroscopy of combustion emissions. His present research concerns laboratory and field experiments on heat transfer and fluid flow in wildland fire.
