Research Interests

Landscape habitat modeling, habitat fragmentation analysis, wildland reserve design, population viability analysis, and Geographic Information Systems (GIS).

Specific projects include:

(1) Integrating landscape habitat analysis into early biological mitigation planning for California Department of Transportation

(2) Spatially quantifying habitat fragmentation due to roads and associated human impacts using the effective mesh size landscape metric

(3) Development of a geographic algorithm to hierarchically delineate habitat patches based on organism specific thresholds for patch perception (PatchMorph): http://arcscripts.esri.com/details.asp?dbid=14977

(4) A predictive spatial model of yellow-billed cuckoo (Coccyzus americanus occidentalis) occupancy in riparian forest patches along the Sacramento River, California

(5) Using a geographical population simulation model to determine the effect of river flow regulation and bank protection projects on the population viability of bank swallows (Riparia riparia) nesting along the Sacramento River;

(6) Modeling the effects of flow regulation scenarios on river channel migration on the Sacramento River

(7) Using GIS to develop of a wildland reserve network for the Sierra Nevada, Modoc, and Southern Cascade ecoregions in California.

(8) A spatially-explicit statewide risk assessment for maintenance and spread of plague disease (Yersinia pestis) in California;
