Ryan Weaver

Ryan Weaver is an Assistant Professor in the Department of Ecology and Evolutionary Biology at Iowa State University, leading the Evolutionary Bioenergetics Lab. His research investigates how organisms meet bioenergetic demands under environmental and physiological stressors, focusing on mitochondrial physiology, mitonuclear coevolution, and carotenoid metabolism. Study systems include fungal pathogens, copepods, snails, and bumblebees.

Education includes a B.S. in Environmental Studies from Virginia Commonwealth University (2013) and a Ph.D. in Biology from Auburn University (2018). His work integrates experimental and bioinformatic methods to explore evolutionary dynamics of energy production systems and signal honesty in animal coloration.

Research themes emphasize mitochondrial alternative oxidase evolution, genomic signatures of mitonuclear interactions, and the role of carotenoids in honest signaling. His 2023 publications highlight critiques of condition-dependent trait theories and methodological approaches in ecological data analysis. Notable work includes studies on hybrid dysfunction in carotenoid production and lifespan predictions from early-life reproductive events.

Grants include a 2019 NSF Postdoctoral Fellowship investigating mitochondrial respiratory chain roles in sexual reproduction. The lab’s interdisciplinary focus bridges evolutionary physiology, genetics, and ecology, with implications for understanding organismal adaptation to challenging environments.
