Meet the team!

Fanny Langlet, PhD

Fanny Langlet earned her Ph.D. in Neurosciences in 2013 at the University of Lille, France, where she investigated the role of tanycytes in the control of energy balance. After completing her Ph.D., Dr. Langlet worked as a postdoc at Columbia University, USA, in the Naomi Berrie Diabetes Center under the supervision of Domenico Accili (2014-2017). During this time, she studied the molecular mechanisms underlying the transcriptional and posttranscriptional control of hepatic gene expression to maintain glucose homeostasis. In 2017, Dr. Langlet got an SFNS Ambizione fellowship at the Center of Integrative genomics (Thorens Laboratory, University of Lausanne). She developed her team, focusing on the gene expression profile for tanycyte glucose sensing. In 2020, she obtained an SFNS Eccellenza fellowship and an ERC starting grant to investigate the molecular mechanisms underlying tanycyte/neuron communication.

Judith Estrada Meza, PhD

Judith obtained a master’s degree in Clinical Nutrition at the University of Granada and a master’s degree in Biosciences at the Ecole Normale Supérieure de Lyon, France. From 2017 to 2020, she joined Dr. Gilles Mithieux’s laboratory in Lyon to pursue her Ph.D. in Neuroscience under the supervision of Dr. Amandine Gautier-Stein. During this time, she studied the role of intestinal gluconeogenesis on the postnatal development of hypothalamic feeding circuits.  In 2021, she joined the laboratory of Dr. Fanny Langlet in Lausanne to investigate the role of tanycytes on the postnatal development of hypothalamic feeding circuits; and the cellular mechanisms underlying tanycyte-neuron communication for the regulation of energy balance, with an emphasis on tanycyte local translation.

David Lopez Rodriguez, PhD

Originally from the Canary Islands (Spain), David obtained a bachelor’s degree in psychology at the University of La Laguna. Following his passion for the field of neuroendocrinology and environmental science, he carried out a master’s degree in neuroscience at the University of Liege (Belgium). During his Ph.D. at Prof. Anne-Simone Parent team (ULiege) and his collaborator Alejandro Lomniczi (OHSU, Portland, USA), he deciphered the cellular and molecular consequences of endocrine disruptors on the female reproductive system across generations. After his Ph.D., he joined the Horizon 2020 FREIA project to decipher biomarkers of environmental exposures. Currently, David is a postdoctoral fellow at Dr. Fanny Langlet’s team where he aims to decipher the biomolecular features of tanycyte-neuron communication in the context of the regulation of energy balance.

Rafik Dali

Rafik obtained his Bachelor in Biology at Sorbonne-Université and his Master in Neurosciences at Université Paris-Saclay. During his pre-master thesis, he worked on the role of astroglial connexins in synaptic plasticity at Collège de France, Paris. During his master, he joined Prof. Lubetzki and Stankoff’s team to work on oligodendroglial factors regulating synapse formation. Rafik joined Prof. Fanny Langlet’s team in 2021 as a Ph.D. student and is currently working on signals involved in tanycyte-neuron communication for the regulation of energy balance.

Antoine has been a laboratory technician in the Langlet group since 2019. He obtained a CFC degree in biology technician from the University of Geneva.

Antoine is responsible for preparing ordering lists and purchasing lab supplies. He works on various techniques with all the lab members.

Tamara Deglise, Lab technician

Tamara did her formation in an Angiologie laboratory at the Centre Hospitalier Universitaire Vaudois (CHUV) from 2018 to 2020. She then stayed for two years in the same lab as a laboratory technician.

In 2022, she joined Prof Fanny Langlet’s lab at the department of Biomedical Sciences at the University of Lausanne as a lab technician.
