Academic Background

I have a Master of Science degree in natural resources at the University of Arizona, where I conducted research that broadly centers on the topics of biogeography, biodiversity, and macroecology, through studies of species diversity patterns, determinants of geographic range boundaries, and species distribution modeling. I am particularly interested in how the geographic distributions of species are influenced by climate and climate change. While some of my work is continental in scale across diverse organisms, a significant component is also targeted at understanding the limits of the distribution of Sonoran desert and Mojave Desert plant species.

As part of my research, I helped support the Botanical Inventory and Ecology Network (BIEN) project (an NCEAS funded working group) through previous roles managing the geographic coordinate validation effort as a Research Intern in Bioinformatics and Geospatial Analysis for an iPlant Seed Project on Botanical Geospatial Diversity Cyberinfrastructure [pdf], and a later role in managing the BIEN species distribution modeling efforts.

NCEAS Working Groups

BIEN Raw Diversity Sample

I worked as part of the Botanical Information and Ecology Network (BIEN), funded by the National Center for Ecological Analysis and Synthesis (NCEAS). The BIEN project aims to combine existing sets of vegetation data for the New World into a database of several million species occurrence records (actually 25+ million and growing). The database forms the largest assembly of data on plant diversity and distribution for both tropical and temperate plant species, and it allows us to address very large-scale questions about how climate and climate change influence species range sizes, abundance and extinction risk.

I also participated in an NCEAS funded project, named Climate and Organisms, that seeks to understand how the environment controls species distributions by assembling a state-of-the-art set of environmental layers that incorporate well-known but rarely used measures having direct links to physiological processes like frost, water stress, growing season, soil properties, drainage properties, etc. The group is assembling these variables into a unified, global, gridded, high resolution GIS data set that will be made available to the public. Finally the group is using this data to explore what factors are actually the most important and most predictive in determining where a species lives and examining questions about the nature of links between the environment and the distribution of organisms.

Research

One of the main goals of my research program is examining how aspects of climate influence the geographic distributions of species across scales, so that we may begin to understand how those distributions may be affected by climate change. With this in mind, I focus on several lines of research that include:

  • Assessing various definitions of a species’ geographic range size: there are several methods used in scientific literature without consensus as to which methods are better than others. How accurate are various computational methods when compared to expert range estimates?
  • Examining the relationship between climate variability and geographic range size. The common perception is that plants with large geographic ranges occupy a broader climatic regime than plants with smaller geographic ranges. Is this true?
  • Testing the climate envelope assumption that the geographic ranges of many species may shift higher in latitude and elevation as a generic response to a warming climate.
  • Investigating whether climate may regulate landscape-level processes, such as maximal woody cover in North American savanna systems.
