Ian Duncan

Ian Duncan is a Professor of Biology at Washington University, affiliated with the Department of Biology. His research focuses on understanding segmental patterning in Drosophila, particularly the developmental mechanisms governing antennal segment identity and body segment differentiation. His work explores the genetic regulation of morphological diversity, with a strong emphasis on the spineless (ss) gene and its role in developmental processes.

Research interests include the molecular basis of antennal specification, the evolution of gene functions across arthropods and vertebrates, and the regulation of patterning within abdominal segments. His lab integrates genetic, molecular, and evolutionary approaches to study developmental pathways such as Hox gene regulation and signaling interactions (e.g., Wingless, Dpp, EGFR).

Recent publications highlight studies on mitochondrial function, metamorphosis control via steroid response genes, and the stochastic expression of spineless in retinal cells. His work bridges basic developmental biology with evolutionary insights, particularly in understanding conserved and divergent genetic mechanisms.

He teaches courses such as Developmental Biology, covering topics like cell signaling in model organisms, vertebrate development, and stem cell biology. His lab is located in McDonnell Hall, and he can be reached via duncan@wustl.edu.
