Luz Irina A. Calderón Villalobos

studied Microbiology at the University of Los Andes in Bogotá, Colombia, followed by research stays at the International Center for Medical Research and Training (CIDEIM) in Cali, Colombia and Boehringer Ingelheim, Germany, and Vienna, Austria. In the early 2000s, she shifted to plant research to the Center for Plant Molecular Biology (ZMBP), and in 2006 obtained a PhD in Developmental Genetics at the University of Tübingen, Germany. Her research as a postdoctoral fellow at Indiana University, Bloomington, and the University of California (UCSD), San Diego, USA involved the structural and biochemical elucidation of the receptor of the plant hormone auxin. Since 2011, she is head of the research group „Signal Integration“ at the Leibniz Institute of Plant Biochemistry (IPB) in Halle (Saale). Her research program seeks to understand how flexible conformations in intrinsically disordered proteins in plants influence protein stability and thereby cellular signaling.
