Research Interests

My lab is engaged in conservation ecology, the use of ecological principles to answer questions related to basic ecological theory, while also informing conservation practices and management of threatened or endangered species.

We are particularly interested in utilizing the most up-to-date mathematical models and statistical methods to inform our conservation ecology work. The tools we most commonly employ include ecological niche modeling (e.g., Maxent), demographic modeling (e.g., integral projection models), and multivariate community statistics. Applying these models and analyses to conservation allows us to make quantitative predictions concerning the set conditions in which endangered populations can persist and the shifts in community structure imposed by different anthropogenic stressors.

We also feel strongly about the importance of parameterizing our models with accurate field data. We are thus engaged in collecting field data on biodiversity, demography, and dispersal from numerous human-impacted ecosystems. These range from the diverse community of non-native reptiles and amphibians in urban Miami to unique South Florida ecosystems (Everglades, Florida scrub, tropical hardwood hammocks) to fragmenting ecosystems in California, Costa Rica, and Sri Lanka.

We primarily study reptiles and amphibians. However, we are also engaged in research on the demography of endangered plants, dispersal of pond invertebrates, and impacts of linear infrastructure development on bird communities.

Teaching Interests

My goal as an instructor is to provide students with toolkits that will enable them to operate as independent researchers. In the Fall, I teach Advanced Biostatistics, which is essential for students to design and analyze their own studies. I cover a wide range of statistical analyses from descriptive statistics through ordination, as well as elements of experimental design to minimize bias and error. In the Spring, I teach Conservation Biology to expose students to the major threats to biodiversity as well as the methods we have developed to combat them. This is accomplished through the lens of case studies drawn from around the world. Both courses are cross-listed for both upper-level undergraduates and graduate students.
