Our Research


The Biodiversity Discovery stream aims to increase our understanding of biodiversity and its evolutionary history. We ask questions about the ecology, evolution, behavior, and natural history of organisms (mostly amphibians and reptiles) using a variety of field and lab-based approaches. Our work relies heavily on preserved specimens from natural history collections at UT and from museums around the world that we borrow to discover and describe new species.

Our Strategy


Biodiversity Discovery stream students are engaged in both the process and analysis toward our research goals.  Researchers are trained to 'think like a scientist' by developing and using critical thinking skills to create new knowledge through research.

 

Biodiversity Discovery researchers will focus on how to:

  • use a variety of approaches and methods, including DNA sequencing, phylogenetic analysis, computed tomography (CT) scanning, and bioacoustics analysis
  • apply best practices for data science using the R statistical software environment for analysis and visualization
  • search for, interpret, and synthesize published primary scientific literature related to the field and evaluate it through critique
  • make arguments from evidence and work together with peers to find solutions
  • apply research skills to collect data, and use those data to formulate and test hypotheses and create new scientific knowledge
  • scientific communication
Impact

Our Impact


Despite centuries of exploration and discovery, most biodiversity remains unknown to science. Documenting earth’s species and inferring evolutionary history is of paramount importance because species underpin the structure and functioning of the ecosystems upon which humanity depends. However, the number of un-described species relative to the human resources available to discover, describe, and classify them is a major challenge. Addressing this challenge requires integrative, organismal research that utilizes innovative biodiversity informatic tools to accelerate taxonomic syntheses, while simultaneously providing broad training to the next generation of organismal biologists.
