Carl's research interests are in forest & range management in wildfire and prescribed fire settings. His research integrates innovative fuels inventory methods, fire monitoring, fire weather, and technology development and transfer. Current projects include measurement of fuel bed properties beneath close-canopies using laser altimetry, development of cost-effective, low power, ad hoc wireless weather sensor networks with fault tolerance, and exploration of new, real-time fire intelligence gathering/delivery capacity. His technical expertise is concentrated in the geospatial technologies of remote sensing and geographic information systems. Carl remains active in operational fire in an effort to link academic activities and fire management.
