Areas of expertise
Aquatic ecology, wetland science, apple snails, invertebrate biology

I am an aquatic ecologist interested in how ecological life histories influence behavior, diversity and distribution of freshwater invertebrates. My research at Southwestern focuses on a group of large freshwater snails - commonly called apple snails because they can reach the size of an apple. Receiving my Ph.D. in the lab of noted exotic species authority Dr. David Lodge at the University of Notre Dame facilitated my early (and continued) interest on questions associated with invasion biology. In Texas, one species, Pomacea maculata (formerly P. insularum), occurs as a non-native, invasive species that my lab has been studying for about 10 years now. In particular, I collaborate with student researchers to investigate multiple aspects of basic life history of this successful invader. Although we have a good sense of its reproductive capabilities, distributions continue to change and there is still a lot to learn. Advances in the field have been happening faster than we can investigate. In addition, we compare and contrast the ecology and diversity of apple snails in non-native habitats with those populations found in the native range of South America. Much of this work has pushed my lab and students into the field of molecular ecology.  Furthermore, the work has expanded to include an international collaboration in Uruguay where native apple snails occur and a partnership with Dr. Kenneth Hayes at Howard University to study patterns of diversity and distribution.

In addition to lab alumni and current students, collaborators on apple snail research include Mariana Meerhoff (email) and colleagues in Uruguay, Mark Kramer (email) at Armand Bayou Nature Center and Dr. Kenneth Hayes (email) and colleagues.

Our current research efforts focus on:

  1. Examining the genetic diversity found in native and non-native populations of apple snails
  2. Investigating whether hybridization occurs among Pomacea spp.
  3. Examining the influence of environmental factors on sensory abilities
  4. Uncovering patterns of cryptic diversity among apple snails in Uruguay
  5. Looking for morphological patterns to tell apart species
