Jason Forthofer is a Mechanical Engineer at the Missoula Fire Sciences Laboratory. Jason’s research involves numerical, field and laboratory studies of heat transfer and fluid flow relating to wildland fires. He is the technical developer of WindWizard and technical developer/ programmer of WindNinja. Other past work includes safety zone size guidelines, development of fire whirl training material, fire shelter design (while at the Missoula Technology and Development Center), and development and deployment of fire behavior field measuring devices. He is currently working to develop a new fire spread model. His fire qualifications include Division Supervisor and Fire Behavior Analyst trainee.
