How freshwater life adapts to a warming, shifting world
The Calloway Lab for Aquatic Evolutionary Ecology studies the evolutionary ecology of stream fishes and amphibians across the rivers of Central Texas, at the intersection of genomics, physiology, and conservation.

All research areasThermal Adaptation
We measure how heat tolerance in stream fishes shifts across generations, linking whole-organism physiology to underlying genetic variation.
Population Genomics
Using low-coverage whole-genome sequencing, we track allele frequency change in wild populations exposed to drought and flow alteration.
Hydrological Disturbance
Central Texas rivers swing between flash flood and drought. We study how these pulses reshape population structure and gene flow.
Applied Conservation Genetics
We partner with state and regional agencies to translate genomic data into management plans for species of conservation concern.
Now recruiting
- ◆One funded Ph.D. position for Fall 2027, focused on landscape genomics of Central Texas stream fishes.
- ◆Undergraduate research assistants for the 2026–27 academic year (paid and course-credit positions available).
