Fanny<\/strong> earned her Ph.D. in Neurosciences in 2013 at the University of Lille, France, where she investigated the role of tanycytes in the regulation of energy balance. Following her Ph.D., she conducted postdoctoral research at Columbia University, USA, in the Naomi Berrie Diabetes Center under the supervision of Domenico Accili (2014\u20132017), studying the molecular mechanisms governing transcriptional and post-transcriptional control of hepatic gene expression to maintain glucose homeostasis. In 2017, Dr. Langlet was awarded an SNSF Ambizione fellowship at the Center for Integrative Genomics (Thorens Laboratory, University of Lausanne), where she established her research team and focused on the gene expression profiles underlying tanycyte glucose sensing. In 2020, she received an SNSF Eccellenza fellowship and an ERC Starting Grant to investigate the molecular mechanisms of tanycyte\u2013neuron communication. Since June 2024, she has been an Assistant Professor with tenure track in the Department of Biomedical Sciences at the University of Lausanne.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Irina Kolotueva, Ph.D.<\/strong><\/h3>\n\n\n\n

Irina received her Ph.D. in Evolutionary Developmental Biology in 2006 from the Technion, Israel, under Prof. Podbilevicz, where she studied developmental processes using fluorescent microscopy in various nematode species. She then conducted postdoctoral research at the IGBMC in Strasbourg, France, with Prof. Labouesse (2007\u20132011), focusing on the organogenesis of the C. elegans<\/em> excretory system using molecular biology, genetic manipulation, and advanced microscopy techniques.<\/p>\n\n\n\n

In 2007, Irina became Head of the Electron Microscopy Center at the University of Rennes, France, where she focused on implementing and refining electron microscopy techniques for diverse basic and applied biomedical studies. She enhanced existing volume EM methods and developed new approaches to improve the efficiency of EM analysis. In 2011, she joined UNIL\u2019s EM facility as a senior researcher, contributing to national and international collaborations and advancing correlative light and electron microscopy techniques, with a particular focus on array tomography.<\/p>\n<\/div>\n<\/div>\n\n\n\n

In 2024, Dr. Kolotuev joined Prof. Langlet\u2019s laboratory to investigate hypothalamic ultrastructure in rodent models, applying volume electron microscopy to study the mechanisms of tanycyte communication and their role in regulating energy balance.<\/p>\n\n\n\n

Judith Estrada Meza, PhD<\/strong><\/h2>\n\n\n\n

Judith<\/strong> obtained a master\u2019s degree in Clinical Nutrition from the University of Granada and a master\u2019s degree in Biosciences from the \u00c9cole Normale Sup\u00e9rieure de Lyon, France. From 2017 to 2020, she pursued her Ph.D. in Neuroscience in the laboratory of Dr. Gilles Mithieux in Lyon, under the supervision of Dr. Amandine Gautier-Stein, investigating the role of intestinal gluconeogenesis in the postnatal development of hypothalamic feeding circuits. In 2021, she joined Dr. Fanny Langlet\u2019s laboratory in Lausanne to study the role of tanycytes in the postnatal development of hypothalamic feeding circuits, as well as the cellular mechanisms underlying tanycyte\u2013neuron communication for the regulation of energy balance, with a particular focus on local translation within tanycytes.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Rafik Dali<\/strong><\/h2>\n\n\n\n

Rafik<\/strong> obtained his Bachelor’s degree in Biology from Sorbonne-Universit\u00e9 and his Master’s degree in Neurosciences from Universit\u00e9 Paris-Saclay. During his pre-master\u2019s thesis, he investigated the role of astroglial connexins in synaptic plasticity at the Coll\u00e8ge de France, Paris. For his Master\u2019s project, he joined the team of Professors Lubetzki and Stankoff to study oligodendroglial factors regulating synapse formation. In 2021, Rafik joined Professor Fanny Langlet\u2019s laboratory as a Ph.D. student and is currently investigating the signals involved in tanycyte\u2013neuron communication for the regulation of energy balance.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Hannah<\/strong> obtained her bachelor\u2019s degree in Biology from the University of Neuch\u00e2tel and her master\u2019s degree in Biomedical Sciences, specializing in Metabolism and Human Health, from the University of Lausanne. During her first master\u2019s project, she investigated the role of lactate in regulating the microglial mitochondrial network. She then joined Prof. Langlet\u2019s team for her master\u2019s thesis, studying the impact of tanycyte-derived signals on the development of hypothalamic neurons regulating food intake in mice. In 2025, Hannah joined Prof. Langlet\u2019s laboratory as a Ph.D. student and is currently investigating how tanycytes orchestrate lipid homeostasis within the hypothalamic cellular network.<\/p>\n<\/div>\n<\/div>\n\n\n\n
