Lecturer (UBE)

PhD at the University of Burgundy.

Master degree in Neurosciences, cognition and behavior, University of Toulouse.

Justin Flaven-Pouchon was hired this year as an assistant professor (ATER) in the 65th section of the CNU to teach courses in cell biology and genetics. He is a member of the GUSTABRAIN team at the Center for Taste and Food Sciences. His research focuses primarily on the relationships between the brain, organs, and behavior, using animal models, particularly the fruit fly. His work specifically addresses food perception, food learning, memory, and the metabolic consequences of diet. After earning a bachelor’s degree in physiology and neuroscience from Claude-Bernard University Lyon 1, he continued his studies at Paul-Sabatier University Toulouse III, where he earned a master’s degree in neuroscience, behavior, and cognition. His early research focused on aversive memory in honeybees and the development of food aversion in Drosophila.

From 2010 to 2014, he completed a Ph.D. in life sciences focused on the perception of fatty acids in Drosophila as well as the metabolic consequences of a diet enriched with fatty acids. His professional career has taken him to France, Chile, and Germany. In particular, he worked at the Interdisciplinary Center for Neuroscience in Valparaíso, and later at the Institute of Cell Biology at the University of Tübingen.

Since September 2024, he has been actively collaborating with researchers studying Drosophila at the CSGA on various projects related to nutrition, particularly on characterizing post-ingestive aversive memory in Drosophila. “Are they capable of learning to avoid foods that have made them sick, and how does this work?” Curiously, this question has yet to be studied extensively in this model organism, despite its relevance to evolution and its potential applications in agronomy. In addition to his scientific work, Justin Flaven-Pouchon has diverse teaching experience with undergraduate students, graduate students, and high school students. He has also supervised numerous master’s and bachelor’s degree interns.
