Dr. Jolly's research is focused in three main areas:
- Physiological controls of flammability in living plants
- Modeling wildland fire potential and behavior.
- Science delivery of spatial wildland fire potential information.

Dr. Jolly's research interests are diverse but they generally focus in two primary areas: physiological controls of live plant combustion and fire danger assessment research.
Much is know about how fires ignite and spread through dead plant biomass but very little is known about how living plants burn. He is interested in describing the physiological constraints to live fuel flammability and better understanding how we can assess the fire potential in live vegetation. Most of the fires throughout the country happen in mixtures of living and dead plants, so it is important to understand the factors that lead to intense and / or rapidly spreading fires. If one can define the physiological criteria that lead to elevated flammability, one can better plan for and respond to wildland fires. Further, it is important to understand how these characteristics are altered when forests are disturbed by insects such as the Mountain Pine Beetle. This new knowledge is critical to providing managers the information they need to best manage public lands throughout the world.
Second, basic knowledge of the fire potential must be translated into metrics that fire managers can use for fire planning and wildfire response. Therefore his second main research interest revolves around modeling and mapping key factors that drive changes in wildland fire potential across landscapes. He has have developed models and systems that can use weather and fuels data to map changes in fire potential and we have made this information available to local, state and federal fire managers throughout the country through the Wildland Fire Assessment System.
Wildland fires are now more common and they burn more area than any time in the record past. New knowledge and new tools are needed to address these changing conditions. Dr. Jolly's research is at the forefront of science and is advancing our knowledge of the conditions lead to extreme and costly wildfires. His work has the potential to help address a critical knowledge gap that could improve our ability to manage landscapes for resilience.
