Gertrud Schüpbach

Trudi Schüpbach (full name Gertrud M. Schüpbach; published name Trudi Schüpbach) is a Swiss-American molecular biologist. She is an Emeritus Professor of Molecular Biology at Princeton University, where her laboratory studies molecular and genetic mechanisms in fruit fly (Drosophila melanogaster) oogenesis.

Research

Prof. Schüpbach's research focuses on signaling pathways that are involved in pattern formation during embryonic development. Using the fruit fly (Drosophila melanogaster) as a model system, she revealed molecular mechanisms underlying the determination of the major axis of the embryo. Performing genetic screens, she identified mutants that result in female sterility of which many affect embryonic body patterning.[1] By that, she contributed to the understanding of maternal factors that are deposited into the forming egg during oogenesis and that are conferred into spatial information within the developing embryo to demarcate distinct functional regions.[2]

Life

Schupbach received her Ph.D. in Biology from the University of Zurich, Switzerland, where she also performed her first postdoctoral work before she continued as a postdoc at Princeton University. In 1990 she was appointed as Associate Professor and promoted to Full Professor in 1994 at Princeton University. Schüpbach is married to Nobel laureate and fellow biologist Eric F. Wieschaus.[3]

Honors

Trivia

Genetic screenings for maternal effect “grandchildless” mutants resulted in the identification of a set of genes that are essential for the patterning of the egg and developing embryo. Many of the affected genes were named by Trudi Schüpbach after royal dynasties that extinguished due to the lack of offspring such as staufen, vasa, valois and tudor.
