Dr. Herzog is a Wildlife Biologist at the Dixon Field Station.  His expertise and interests are in quantitative analysis of ecological data with specific emphasis in avian systems and the estimation of demographic parameters. Dr. Herzog also develops statistical tools and programs used in the analysis of demography and life history.

Before joining USGS, Mark was the co-Director of the Informatics Division at PRBO Conservation Science, where he lead the development of quantiative techniques for the analysis of avian data, and helped create the highly successful California Avian Data Center. 

Within his current position, at USGS, Mark leads the quanitiative analysis of avian ecology research being performed throughout the western United States by USGS Dixon Field Station staff.  He has developed a number of technical statistical programs (primarily in the R programming language) that can be used to estimate demographic and population parameters such as survival, nest survival, nest success, and densities of avian populations.  He is also leading efforts to examine the climatic impacts on avian demographic paramaters in order to better understand and predict future changes that will occur to avian populations due to ongoing climate change.
