Philip Higuera is a professor of fire ecology in the Department of Ecosystem and Conservation Sciences at the University of Montana. He directs the PaleoEcology and Fire Ecology Lab, funded largely from the National Science Foundation and Joint Fire Science Program, and he teaches undergraduate and graduate courses in fire and disturbance ecology. Research in his lab spans western North America and broadly addresses interactions among climate, wildfire, ecosystems, and people, across timescales of years to millennia. This work has revealed how fire activity varies with climate change in recent decades and the distant past, and how forest ecosystems respond to past and ongoing changes. Since 2016, collaborative efforts have increasingly focused on understanding wildfire as an integrated social-ecological phenomenon, helping address current societal challenges centered around living with wildfire.
