I work on invasive carp population modeling. I am a math modeler interested in developing, applying, analyzing, and evaluating models of biological and ecological systems. I am especially interested in population dynamics, invasive species, and working in close collaboration with biologists and other scientists.

Assessing the suitability of YY males and ZZ females as an invasive species population control method across life histories
Natural resource managers use tools to control invasive species. In theory, stocking YY males or ZZ females would allow managers to skew sex ratios until populations collapse. In combination with other suppression methods, such as removal, this approach could be incorporated into Integrated Pest Management plans. For example, fishery managers have stocked YY males to control isolated non-native brAuthorsRichard A. Erickson, Hannah Mann Thompson, Stacie A. Kageyama, Grace M. Andriacchi, Aaron R. Cupp, Reynaldo Patiño, Jon AmbergMetaIPM: Placing integral projection models into a metapopulation framework
Metapopulation models include spatial population dynamics such as dispersion and migration between subpopulations. Integral projection models (IPMs) can include demographic rates as a function of size. Traditionally, metapopulation models do not included detailed populaiton models such as IPMs. In some situations, both local population dynamics (e.g. size-based survival) and spatial dynamics are iAuthorsRichard A.
