Nina Kraus
University of Vienna

I am a researcher in evolutionary developmental biology working at the intersection of developmental biology, comparative physiology, and philosophy of biology. My research focuses on how environmental conditions regulate developmental processes and shape evolutionary trajectories, with a particular emphasis on the vertebrate heart.

During my PhD, I became increasingly interested in approaches to development that move beyond gene-centered explanations. This led me to develop a theoretical framework in which organism–environment interactions are understood as constitutive components of developmental mechanisms rather than external influences. Drawing on comparative studies across vertebrates, I investigate how physiological factors such as oxygen availability and metabolic transitions influence cardiomyocyte behavior and cardiac morphogenesis.

My work is informed by ecological developmental biology and recent philosophical analyses of mechanisms and evolvability. I am particularly interested in how both locally and organismally constructed environments such as those arising in reproduction function as regulatory systems during development.
